Impacts of ethnoveterinary medicine integrated with livestock farm technologies on the performance and antimicrobial resistance of indigenous goats in South Africa –A review
93-103Views:42Ethnoveterinary medicine and livestock farm technologies represent a junction of innovation and tradition with the aim to accomplish livestock systems that are resilient, productive, and sustainable to meet 21st century challenges, especially the antimicrobial resistance issue. This article aims to emphasise the impacts of integrating ethnoveterinary medicine with livestock farm technologies on the performance of indigenous goats in South Africa. With the growing concern over antimicrobial resistance in livestock, there is a pressing need for complementary approaches to the health of animals and their productivity. In this review, the aim evaluated whether an integrative approach could offer a sustainable alternative that benefits animal health and productivity while addressing the concerns of antimicrobial resistance. Comparative study designs across multiple indigenous goat farms were used to integrate specific medicinal plants in ethnoveterinary medicine with present-day livestock technologies that are used to monitor the effects on livestock performance indicators and antimicrobial resistance patterns. In the treated populations, the outcomes were indicative of substantial improvements in reproduction and growth rates, and alongside, there has been a notable decrease in the markers of antimicrobial resistance. Therefore, it is proposed that through these discoveries, the integration of these traditional and modern approaches not only improve the performance of indigenous goats but also contribute immensely to the mitigation of risks associated with antimicrobial resistance.

Effects of bioactive plant extracts on immune-related gene expression of common carp (Cyprinus carpio)
49-56Views:271In recent years, intensive fish farming has led to an outbreak of several diseases, and the health status of fish can affect the economy of aquaculture. Since fish health and intestinal health are in correlation, it may also have an impact on immunity. Accordingly, many natural feed additives are being used to improve immune functions. In our study, carotenoids, oligosaccharides, and anthocyanins were applied at 1 m/m% in feed to investigate their effects on cytokines, such as interleukin-1β (IL-1β), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), and interferon regulatory factor-1 (IRF-1) in spleen and mid-intestine of 6 months old carp. Gene expression analysis was carried out to examine IL-1β, IL-8, TNF-α, and IRF-1 mRNA levels in fish spleen and mid-intestine. The gene expression level of pro-inflammatory IL-1β decreased in the mid-intestine of carotenoid-fed carp compared to anthocyanin supplemented group, but the effects of the bioactive plant extracts were not observed on the examined cytokines compared to control fish.

Effect of genotype on the hematological parameter of TETRA-SL and Hungarian Partridge coloured chickens at young age
99-104Views:205Indigenous chickens are well known for their dual-purpose function and palatable meat. However, the information on their hematology parameters is lacking and hence hampering the poultry industry production of local breeds. The main objective of this study was to examine the hematological parameters of Hungarian Partridge Coloured hen (HPC) and TETRA-SL (TSL) genotype and determine the hematological reference interval values. This trial was part of the larger experiment where a total of 200 chicks (HPC + TSL) were reared. For this trial the blood samples were obtained from brachial wing veins of 8 chicks of each genotype for blood hematological analysis. The results indicated that some of the hematological parameters such as red blood cells-RBC, white blood cells-WBC, hemoglobin-Hb, hematocrit-Ht, platelets-Plt, lymphocytes-LYM, and granulocytes-GRAN were significantly affected by the genotypes (p < 0.05). The genotype did not affect the mean corpuscular volume-MCV, mean corpuscular hemoglobin-MCH, mean corpuscular hemoglobin concentration-MCHC, and GRAN (p > 0.05). The hematological reference interval values were slightly higher in the TSL genotype compared to HPC chicks. It is concluded that genotype has a significant effect on the hematological parameters. The results from this trial will be help and design the baseline reference values for the HPC genotype which will be useful in assessing the health status of these indigenous chickens.

Strategic Steps in the Sheep and Goat Branches
61-68Views:130The balance of the sheep and goat branches can be summarised as follows:
If the increase in stock size, specific yields, genetic improvement and modernisation are not realised, several thousand shepherds will lose their jobs and possibilities to work, and their families will lose their only source of livelihood.
Several hundred hectares of grassland will become weedy and the costs of crop protection will increase in these regions. Pollen pollution, the number of allergic ailments and medical costs will increase, mentioning only the main disadvantages. Its financial requirement is nearly equal to the one required for development without any essential compensation or production.
In order to develop a competitive branch, a subsidisation of 10-20 billion HUF is needed until the accession of Hungary to the EU, depending on the scale and progressivity of development. The subsidisation and realisation of the strategic steps would result in:
– the establishment of a registered livestock with 1.5 million ewes, which would ensure better market position for the branch in the EU (5%),
– the establishment of a competitive and marketable branch with a production value of 15-25 billion HUF, calculated using the present price level (after accession, the branch would be self-operating and profitable, with the 6-8 billion HUF/year normative subsidisation by the EU),
– the establishment of a genetic potential which would ensure our participation in profitable international breeding animal market, which provides extra profit,
– the establishment of a sheep husbandry with better genetic potential and phenotypic performance, producing a quality of international level,
– the maintenance of the workplace of more than 10.000 people (saving 3-5 billion HUF/year of the budget),
– the maintenance of the condition of growing areas of grasslands with their advantages (crop protection and public health) whose financial effect is considerable. -
Study of animal welfare status and heat stress measures applied in dairy cow herds in Hungary
79-82Views:102The following material focuses on dairy production and climate related issues in Hungary. All the data was gathered during PhD
project: Study of animal welfare status in dairy cow herds in Hungary. Relations between animal welfare and climate changes expressed by
increase in temperature are described. Extremely hot weather creates hard conditions for milking cows when animal welfare is highly
compromised. From the preliminary results obtained one might formulate hypothesis that there are still areas on the farms where immediate
actions should be taken to give a relief to cows in hot seasons. There was found significant number of farms with too many animals per one
water trough, dirty water troughs, limited access to water troughs and hazardous surface for cows in critical places where many animals are
gathered. Calves with not sufficient amount of water in hot days and other parts of the year were reported. Silage exposure to the sun and
mouldy food in a silage clump was also found to be an important factor in monitoring impact of warm weather. Half of the farms letting
animals to spend time on the pasture or paddock did not provide shade for animals. Low conception rate of first insemination was predicted
to be influenced by heat stress, what is proved by lack of heat decreasing measures taken on the farms. -
Effects of diets with different fibre content on the performance of rabbit does and on parasitological infection
41-44Views:91The effect of two diets with different fibre contents was examined on rabbit does’ performance and parasitological infection. Diet P2 had 1% higher crude fibre, ADF and starch contents than that of diet P1. The performance of 12–12 does and litters per group were examined during two consecutive inseminations. In both dietary groups, according to a 49-day reproduction rhythm, the does were artificially inseminated 18 days after kindling. Most production traits were not affected by the diets (kindling rate, weight of does and their kits, feed intake, mortality; P>0.05). Significant differences were only found in litter sizes as the number of kits was lower in P1 diet fed group at all examined days of lactation. The significant “Diet x Reproduction cycle” interaction showed that the litter sizes of dietary groups did not differ at the first examined insemination, however at the subsequent reproduction cycle 6–8% lower litter sizes were counted in P1 fed does compared to group P2 (litter size at 4 day: 9.00 vs 9.58–9.92, P = 0.004; litter size at 11 day: 8.83 vs 9.58–9.92, P = 0.037 for diet P1 at the 2nd reproductive cycle compared to all the other cases, respectively). The two diets with different compositions did not affect most of the production results of the rabbit does and their kits, but the lower litter size of does consuming P1 diet at the second examined lactation suggests the adverse effect of P1 diet’s long-term use. From the collected manure samples not any parasites were detected which presents a very favourable picture of farm from the point of view of hygiene and animal health.

Differences in content of beet root and beet root juice, and it’s suitable to develop functional foods from animal sources
53-57Views:288In Western medicine is beginning to increasingly focus on the key role of healthy nutrition and lifestyle in preventing certain diseases. Therefore, it is important to emphasize the importance of primary prevention in our country, and to promote it; not only the health care team work, but broaden the recommended foods, which have benefit for human health as well.
Polyphenols are antioxidants, which are easily consumable with diet, however, food processing can influence the level of them.
In our study, nutritional assessment was made of raw beet root and a juice, made from this beet root. We investigated in which special diet referenced to eat this foods and whether this is suitable to develop functional foods from animal sources as a row material.

Sow removal patterns in commercial breed-wean herds of Midwest, USA
9-14Views:348An observational retrospective study was done to provide up-to-date information on recent sow removal patterns from 9 breed-wean herds of Midwest USA. The study comprised of sow’s removal reasons and removal types of F1 Landrace x Yorkshire gilts entered in the herds between 1st Jan 2014 and 31st July 2016. Data was extracted from existing database on Dec 2018 and 15% of the sows were still active in the herds hence not included in the study. Descriptive statistics showed that out of the 20,009 removed sows, planned removals comprised of farrowing productivity (FP) 3,523 (17.6%) and old age (OA) 1,785 (8.9%) while unplanned removals consisted of reproductive failure (RF) 7,786 (38.9%), health problems (HP) 2,629 (13.1%), locomotion problems (LP) 1,473 (7.4%) and conformation issues (CI) 1,350 (6.8%).‘Did not conceive’ and “No heat” were observed as the main contributing factors accounting for 37.6% and 32.9% respectively for gilts & sows removed by RF.13.5% of the gilts (Parity 0) were removed from the herds before attaining their first litter of which 64.1% of their removals was due to RF. Removal type consisted of slaughter (S) 85.0%, found dead on the farm (DoF) 10.8% and euthanized (E) 4.2%. The research findings depict an upward trend of sow RF removals in the US swine herds posing a serious concern for US swine producers. Characterization and quantification of sow removals gives a revelation on the deeper intrigues about the vulnerability of the various parity in respect to common causes of RF. This helps swine producers to decisively improve on gilt replacement selection, reproductive efficiency, health and nutrition management all aimed at increasing overall swine productivity and efficiency in management. Swine farmers in the US can now focus their efforts towards curbing unnecessary RF removal within parity specifics.

Effect of feeding linseed on the fatty acid composition of milk
45-50Views:234In the last decades many researches were made to change the animal product food’s composition. The production of better fat-compound milk and dairy products became a goal in the name of health conscious nutrition. These researches were motivated by the non adequate milk fat’s fatty acid composition. There have been made researches in order to modify the milk’s fatty acids’ composition to reach the expectations of functional foods. With the optimal supplement of the feed can be increased the proportion of the polyunsaturated fatty acids and can decreased the saturated fatty acids. Row fat content of milk was not decreasing in the course of examination neither of the cold extruded linseed nor the whole linseed supplement as opposed to observations experienced by other authors. In case of monounsaturated and polyunsaturated fatty acids when supplementing with cold extruded linseed the most significant change was observable in the concentration of the elaidic acid, oleic acid, linoleic acid, alfa-linolenic acid, conjugated linoleic acid. In case of saturated fatty acids the quantity of palmitic acid and myristic acid lowered considerably. When observating the feeding with whole linseed the concentration of many fatty acids from the milkfat of saturated fatty acids lowered (caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid). The quantity of some unsaturated fatty acids was showing a distinct rise after feeding with linseed, this way the oleic acid, alfa-linolenic acid, conjugated linoleic acid, eicosadienoic acid. The aim of the study was to produce food which meets the changed demands of customers as well. The producing of milk with favourable fatty acid content from human health point of view can give scope propagate the products of animal origin. -
Consumption tendencies of foods of animal origin in Hungary
7-17Views:129One of the most important indices of the population's food consumption are the quantities of the consumed foods expressed in a natural measure. In the course of my examination from the 1980 years I examined how our dietary habits changed. I was able to demonstrate it by the time series examination well, in which years and in a what kind of measure these consumer changes occurred. The trend analysis was in it onto my help, that let me be allowed to depict his beat as the changes of the food consumption visual.
In his totality the Hungarian population nutritional and from his consumer customs we may relate that the present nourishment increases it unambiguous the diet pendant the risk of illnesses, furthers their development, aggravates their effect, and contributes to the population's adverse health conditions powerful.
It was over in some years, in a decade on a unfortunate manner, we lost the natural instinct of the selection of the food in a considerable part. Our diet fundamental the narrower and the customs of wider environment, his rules, the social values, beliefs define it. Because of this to feed it is necessary to study it.
The changed and the health-conscious nourishment would be important for him herding back into a upturned dietary habit correct bed with a wide circle recognizing him with the population, his role could be big for the healthy, or functional foods. The nourishment gives his pleasure likewise while we take over healthy foods.
The recognition of the changes of the demand and accompanying him with attention could be the domestic food producers' fundamental interests. The consumer types and the market segments should be mapped, that they suitable marketing a strategy can be aimed at it, and into the direction of the healthy nutrition to push away, and would be need onto an efficient informative campaign, onto an advertisement message formulated well, onto the making aware of this, that let the advertisement supply an educational function in one. -
Presence, feeding and health status of collared doves (Streptopelia decaocto Friv. 1838) on animal breeding farms
49-54Views:119In the course of our examinations we were determining the gender of collared doves (Streptopelia decaocto) feeding at animal breeding farms by biometric data. We were estimated their nourishment and necropsies were carried out.
We compared the results of the nutrition analysis with similar data of collard doves feeding at agricultural areas.
We analyzed the crop and gizzard content and recorded the body proportions of collard doves that were captured between December of 2004 and August 2005. In the course of the necropsy examinations we did parasitological, bacteriological examinations as well as examinations for the detection of Newcastle disease. In the course of the gender analysis of the collard doves that were collected at animal breeding farms, both the wing length and the length of the third quill-feather has shown a significantly greater value in the case of males (p>0.05).
From the orts found in the crop and gizzard it has been stated that the feed consumed the most was corn (80.77% m%). The collared doves consumed much less other cereal seeds (wheat 0.82%, barley 1.26%).
In the course of the necropsy examinations done in the Veterinary Institute of Debrecen, the birds proved to be free of parasites, and the results of the Salmonella and Newcastle disease analysis were negative as well. E. coli bacteria had been detected in the liver of not more than three birds. -
Mycotoxin contamination in maize triggered by arthropod pests and the related protection possibilities
59-64Views:143Mycotoxin contamination in harvested maize has increased in the last decades, which can be unequivocally back to the plant health troubles caused by global warming. The increasing of wounds in maize crops was occurred by climate change both on direct (hailstorm) and indirect
(newly appeared pests) ways. In additional, the settling phytopathogenic microfungi on these plant wounds inflict serious human and animal health problems.
The changing of Hungarian arthropod pests assemblages stand in the background of this dangerous nuisance complex. The spreading of European corn borer (Ostrinia nubilalis Hbn.) bivoltine ecotype as well as the newly appeared adventive species [cotton bollworm Helicoverpa armigera Hbn.), western corn rootworm (Diabrotica v. virgifera LeConte), fourspotted-sapbeetle (Glischrochilus quadrisignatus Say)] in Hungary can be responsible for this situation. In total, all technological elements, which obstruct the damage of these chewing mouthparts pests, as well as moderate the mechanical damage of maize, can be contribute to the reduction of both these phytopathogens injuries and mycotoxin contaminations. -
Optimal age of breeding gilts and its impact on lifetime performance
15-20Views:511Age at first breeding and lifetime reproductive performance was analyzed on 17,558 F1 Landrace x Yorkshire gilts from 9 piglet producing herds of Midwest, United States entered in herds between 1st Jan 2014 and 31st July 2016. At the time of data collection Dec 2018, 15% of the sows were still active in the herds hence excluded from the analysis. Individual gilt data included date of birth, age in days at first mating, piglet total born by parity, lifetime piglet total born and reason for culling. Quality data checks were done before analysis to eliminate all outlier values together with sows that had no entry information for any listed category. The total database of the sows was classified into 6 classes according to age at the first mating in days 170-190(n=754), 191-211(n=4683), 212-232(n=7123), 233-253(n=3385), 254-274(n=1002) and 275-369 (n=611). Piglet total born obtained from each sow during the lifetime production was significantly (P < 0.05) greater for gilts bred between 233-253 days of age at first mating. Gilts that were bred at <233 days appeared to have a higher risk of removal by farrowing productivity as compared to the other groups. However, the results show that the risk of being culled due to health problems and conformation issues increases as the age at first mating is delayed. Overall reproductive failure appears to be the most economical culling reason across all age groups. There is a need to evaluate the best management decisions for gilt initiation in a herd to maximize her lifetime performance. The results indicate that gilts mated for the first time at the right age, 233–253 days, are more productive, both in lifetime total born and have a minimal risk of culling due to farrowing productivity.

Current Conditions and Opportunities of Biofarming in Hungary
150-156Views:88The aim of organic farming is not to maximize income, but to achieve optimal product quality. It is completed by the tightest possible material, and energy flow within the farm. Organic agriculture significantly reduces external inputs by avoiding the use of chemo-synthetic fertilizers, pesticides and pharmaceuticals. Instead it works with nature to increase both agricultural yields and disease resistance. Total independence of external resources can not be achieved in Hungary due to the small-scale of organic animal husbandry. Some materials in limited quantities can be purchased from external resources, though the group of these materials is strictly regulated. Organic farming harmonizes with the concept of European multifunctional agriculture, because besides farming, it includes social considerations, as it helps to maintain natural resources and the relationship between people and their environment, and provides a living for those living in the region.
As regards organic farming the fertility of the soil and the health of vegetation can be influenced in various ways. Farmers have to be highly skilled and able to manage a farm with great expertise. Generally it can be stated that as the use of non-organically produced products is limited, the opportunities to correct failures made by the farmer are minimal, contrary to conventional farming. Farmers must be intent on developing the tightest material- and energy flow. This means that organic farms ideally have both animal husbandry and crop production. This energy and skill demanding system of farming is compensated by state subsidies, growing market share and relatively high prices for organic products. -
Coagulase-negative staphylococci in ewe udder surface and raw milk samples
221-225Views:157Coagulase-negative staphylococci (CNS) are among the major causes of subclinical mastitis in dairy ewe flocks. This has a financially significant impact on the ewe dairy sector and consumer health. The determination of the bacterial count, particularly CNS, is critical in terms of the quantity and quality of ovine milk. Thus, the purpose of this study was to quantify the CNS count in the udder surface and raw milk samples of the ewe, in addition to identifying CNS strains (n=8) collected from udder surface and individual raw milk samples by 16S rRNA gene sequencing. A total of 164 samples of udder surface and raw milk originated from four sheep farms were tested. The obtained values were compared between the different farms. Furthermore, values during 2018 and 2019 in the case of Farm I were compared. Significantly higher (p<0.05) average count was observed in udder surface samples taken from Farm I (2.8±1.0 lg CFU/cm2) than that of Farm III samples (2.3±0.6 lg CFU/cm2). In the case of individual raw milk, the higher value was observed in samples derived from Farm III (3.5±0.9 lg CFU/mL), while the obtained value was significantly lower (p<0.05) in samples originated from Farm IV (1.8±0.4 lg CFU/mL). In the bulk tank milk samples, the highest mean value was 5.3±0.4 CFU/mL, and there was no significant (p>0.05) variation between farms. Coagulase-negative staphylococci counts were decreased to a certain extent in both sample types tested during 2019 except for individual raw milk derived from the Tsigai breed. The correlation between the mean CNS counts of udder surface and individual raw milk was very weak (r=0.048). Staphylococcus simulans, Staphylococcus auricularis, and Staphylococcus equorum were identified by molecular sequencing and Staphylococcus simulans were the most frequently identified CNS species. A higher CNS count of bulk tank milk than individual raw milk indicates possible contamination during milking and storage. Therefore, further studies are required to investigate the other sources of bulk tank milk contamination to improve the hygienic quality of milk.

Application of yeasts fortified with microelements – Review
101-106Views:131Microelements are increasingly becoming into the focus of interest from both a point of view of nutrition science and feeding. An always growing care must be paid to the microelements coverage both in human and animal organisms because of incorrect alimentation habits and
unsatisfactory feedstuff nutrition value. For the increased supply of the micro-nutrients, enrichment or fortification with microelements can not only be realized with traditional foodstuffs and forage but there are already alternative ways such as single-cell proteins from yeasts directly enriched or fortified with microelements for the purpose.
We would like to draw the attention that the production of these items is more favourable in comparison with traditional foodstuffs or forage since yeasts are capable to multiply microelement levels compared to their original state, and establish organic bonds with them.
For this purpose, we explored and analysed the scientific literature, studies and research results on this subject, that is why we stressed the significance of yeasts, the features and health effects of certain microelements, as well as the possibilities for use of yeasts enriched with micro-nutrients. -
Coherence and connection between the good pond culture practice and the environment conscious management
60-73Views:76According to the data indicating the decline and restructuring during the past decade, as well as the trend in the European Union member states, it can be expected that the role of traditional agriculture and fish production in direct rural employment decrease further. This also values those strategic directions for restructuring that will lead fishculture from quantity driven to quality production along with sustainable development (i.e. environmental conscious production) and multifunctional farming. This way the economic and social tensions caused by the concentration of the production and labour output can be mitigated.
It is laid in the 1257/1999 Act on rural Development that farmers that enrol the agri-environmental scheme should follow the “Good Agricultural Practice” on the whole managed area. In case of agri-environmental schemes this is a precondition for which no grants are given.
The adaptation of “Good Agricultural Practice” in fishproduction,where it is called: “Good Pond Culture Practice” is considered important on the basis of the above mentioned. This programme is undertaken in co-operation with the Research Institute for Aquaculture, Fisheries and Irrigation, University of Debrecen, Faculty of Agricultural Economics and Rural Development and the Association of Hungarian Fish Farmers and Product Council.
The European Commission proposed the formulation of the European Fisheries and Aquaculture Fund (EFAF) for the period 2007-20013, which will replace the Financial Instruments for Fisheries Guidance (FIFG), but it also consists of several new elements and will be working differently, too. According to the proposal the budget for the Fund will be nearly 5 billion EUR (4963 million EUR). The development level of aquaculture and fisheries and the social and economic significance in the given member state will be considered when distributing the Fund between the Member States.
According to the plan the Fund is organised along five priority axes, of which the most important for the Hungarian fisheries sector is No. II: Aquaculture and the processing and marketing of aquaculture and fisheries products. The main measure areas are the followings:
1. investment support for aquaculture;
2. support for aquatic-environmental schemes;
3. environmental- and animal health issues;
4. investments in processing and marketing
In case of accessing support under measure area No. 2 farms are obliged to meet the requirements of the scheme beyond the “good management practice” for 5 years, which is to be supervised by the approved body of the Member State. For this reason our work is considered to be substantial.
Approval of the application of “Good Pond Culture Practice” is based on two elements: first the prevailing environmental and nature conservation regulations, as well as the list of controllable conditions in the new agri-environmental agreements are to be met. “Good Pond Culture Practice” are to be conducted on the whole farm area. Its main elements are:
- nutrition management,
- feeding,
- pond maintenance,
- stocking,
- harvesting,
- animal welfare (storage and over-wintering). -
Effect of using antioxidants as feed additives in the diet of dairy cows on the vitamin E and lycopene content of milk
69-72Views:115In 2007, the aim of an Ányos Jedlik program and call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants – in this case: vitamin E and lycopene – used as feed-additives can increase the antioxidant content of milk. The milk with an
increased level of vitamin E and lycopene content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E as feed-additive can significantly increase the amount of vitamin E in the milk. The use of lycopene as feedadditive also gave good results. At the beginning of the experiment, the lycopene content of the milk was below the detection limit, while in the post-feeding milk samples the lycopene became detectable. Based on our results, we are of the opinion that further experiments and analyses are needed regarding the quality of food of animal origin and animal health. -
Study of animal welfare status in dairy cow herds in Hungary – looking for causes of lameness
47-50Views:175In the last 20–30 years lameness in cattle was found to be third the most influential disease next to mastitis and reproduction disorders. Studies have been established to explore reasons for lameness and prevention. The problem with more robust prevention plans is that knowledge and research evidence is not strong enough to run an effective prevention plan. The aim of the research is to look for reasons of lameness by observing number of cows on 6 farms during 2 lactations. Performance data will be put together to body condition score (BCS) and lameness scores. Other examination is focused on monitoring of 40 farms. This part of the project is more related to extension, collecting and sharing solutions for decreasing lameness. Producers are advised what kind of measures are possible to reduce occurrence of lameness. Effectiveness of those actions will be measured at the end of the study. The first preliminary results show lack in almost all preventive measures needed to be taken in minimising lameness. Those areas are related to poor facilities, lack of straw, problems with labour and basic management.

Some aspects of food safety from animal origin
153-155Views:118The relationship between the civilisation illnesses and incorrect nutrition can be considered as demonstrated. The functional foods having one or several nutritional- biological advantage can contribute to the healthy nutrition and to improving the quality of life. Beside the healthy nutrition it is an another important requirement that the food does not contain pathogens or substances of chemical and biological origin namely it has to be safe.
In this publication the foods of animal origin were investigated in the point of view of public health hazards arising during their production and processing.
The contamination and infection of food raw materials, the consequence of chemical substances getting in or developing it the food, the judgement of food deviring from genetically modified or cloned animals are discussed. -
Effect of allithiamine on the level of hyperglycaemia-induced advanced glycation end products
41-44Views:256Diabetes mellitus is a rapidly growing public health burden in both developed and developing countries. Diabetes mellitus is accompanied by hyperglycaemia, which can cause tissue injury by several mechanisms. One of these is the formation of advanced glycation end-products (AGEs). In this study, the effect of allithaimine, a fat-soluble thiamine derivative, was investigated on hyperglycaemia-induced AGEs levels using human umbilical cord vein endothelial cells (HUVECs) as a hyperglycaemic model. HUVECs were isolated by enzymatic digestion, characterized by flow cytometer and treated 30 mM glucose plus allithaimine or thiamine or cell maintenance medium as control. Allithiamine was synthesized and purified. The structure of the synthesized and isolated compound was verified by reverse phase HPLC and MALDI-TOF. AGEs were evaluated by ELISA. Collectively, our results indicate that allithiamine can reduce level of the hyperglycaemia-induced AGEs similar to thiamine.

The strengthen of the second pillar in the European Union and Hungary
88-94Views:84The Common Agriculture Policy (CAP) took shape in the early 1960s. At that time the first action was to stop food shortages. Among the objectives of the Treaties of Rome appeared the subvention of rural development had not yet.
Rural development appeared, in 1992, in connection with accompanying measures, and by end of decade, the European Agricultural Model had taken shape. Agenda 2000 pointed out the direction of rural development and introduced the first and second pillars in the CAP. The regulations of rural development were simplified by 1257/1999/EC, which stressed the importance of rural development to and it has to continue the principle of subsidiarity and has to be decentralized.
The last enlargement raised new problems, the mid-term review of Agenda 2000 occurred and resulted in a new CAP-reform in 2003. The 1783/2003/EC rural development regulation modified the previous regulation. According to the new regulation it is necessary to strengthen the new rural development policy, enlarge the circles of accompanying measures, place greater emphasis on requirements of environment, human resource, animal welfare and plant health. Digression and modulation take part in the new CAP-reform in order to increase the role of rural development in the common budget.
In the next budget from 2007-2013, the European Union wants to create a single rural development fund and simplify programming, financing, monitoring. The EU wants to enlarge the instruments of rural development with a four axis model. -
Microbiological status of bulk tank milk and different flavored gomolya cheeses produced by a milk producing and processing plant
73-78Views:246The microbiological quality of milk is important not only for food safety, but it can also influence the quality of dairy products. In this study, our aim was to assess the microbiological status of the bulk milk of a milk-producing farm, and some natural and flavored (garlic, dill, onion) gomolya cheeses made from pasteurized milk produced by their own processing plant. We determined the number of coliform bacteria, Escherichia coli, Staphylococcus aureus, and molds of three milk and eight cheese samples. The tests were conducted between July and September, 2017.
In bulk milk, the mean coliform count was 3.83±0.17 log10 CFU/ml; the mean E. coli count was 1.38±0.14 log10 CFU/ml; the mean mold count was 3.74±1.30 log10 CFU/ml; and the S. aureus count was <1.00 log10 CFU/ml, respectively. The mean coliform count in gomolya cheeses was 3.69±1.00 log10 CFU/g; the mean E. coli count was 2.63±0.58 log10 CFU/g; the mean S. aureus count was 3.69±1.35 log10 CFU/g and the mean mold count was 1.74±0.37 log10 CFU/g. The amount of coliforms detected in different flavored gomolya cheeses were significantly different (P<0.05). More than 10 CFU/g of E. coli was found only in the dill flavored cheeses, and S. aureus was found only in dill (3.66±1.86 log10 CFU/g) and onion (3.71±0.52 log10 CFU/g) flavored gomolya cheeses. Based on the obtained results, it was found that the amount of coliform bacteria and E. coli in bulk milk exceeded the limit set in regulation of the Hungarian Ministry of Health (MoH) 4/1998 (XI. 11.) and the amount of S. aureus was below the limit. For gomolya cheeses, the S. aureus count exceeded the limit. The amount of coliform bacteria remained above the limit in cheeses, except for the garlic flavored gomolya cheese. In cheeses, a larger E. coli count was detected than in the bulk milk, but there is no specific limit for cheeses in the regulation. The mold count exceeded the limit specified in the regulation in cheeses, but a lower value was detected relative to milk.
The results show that, in the case of bulk milk and gomolya cheeses, certain detected quantities exceeded the limit values set forth in regulation of MoH 4/1998 (XI. 11.). The results indicate an inadequate microbiological state of the raw material and the finished products. The reasons for these are due to reduced technological hygiene or the inappropriate handling of raw material and finished products. In this study, we have summarized the results of our preliminary studies, which can provide a basis for further hygiene studies.

Element content analyses in the Institute for Food Sciences, Quality Assurance and Microbiology
203-207Views:122The role of chemical elements to ensure and promote our health is undisputed. Some of them are essential for plants, animals and human, others can cause diseases. The major source of mineral constituents is food, drinking water has a minor contribution to it, so the knowledge of elemental intake through food is crucial and needs continuous monitoring and by this way it promotes the food quality assurance and dietetics.
With the evolution of spectroscopic methods increasingly lower concentrations could be determined, so the elemental composition of a sample could be more precisely and fully described. Due to the results the gathered knowledge up to the present is supported and new observations can be done helping us to understand such complex systems as biological organisms are.
The quality of a food is determined by the full process of its production, consequently it starts with agricultural production so elemental-analysis usually cover the whole soil – plant – (animal) – food chain, by this way the „Fork-to-Farm” precept is true in elemental analysis field also.
The history of elemental analysis in the University of Debrecen, Centre for Agricultural and Applied Economic Sciences, Faculty of Agricultural and Food Sciences and Environmental Management, Institute of Food Processing, Quality Assurance and Microbiology goes back to 1980s when the so called Regional Measurement Central gave the background for research. The continuous deployment resulted in an obtain of an inductively coupled plasma atomic emission spectrometer (ICP-AES) in 1988, which extended the scope of examinations due to its excellent performance characteristics
compared to flame atom absorption (FAAS) and flame emission spectrometers (FES). The instrumental park retain up to date correlate to the developing analytical techniques due to acquiring a newer ICPAES in 1998 and an inductively coupled plasma mass spectrometer in 2004 – which sensitivity is three order of magnitude better compared to ICP-AES. The Institute supports the work with its own ICP-AES and ICP-MS since 2011.
