Effect of bacteria containing bio-fertilizer on Cd-tolerance of corn and sunflower seedlings in nutrient solution
15-21Views:205Bio-fertilizers promote the nutrition uptake, firstly enhance the baring and mobility of nutrients, on the other hand biofertilizers elevate nutrient uptake in direct way. Although there are a lot of questions about their application in polluted soils. The cadmium ion is easily collectable and also transportable inside plants. Thus the Cd can get into the food-chain causing public health problems. The cadmium treatment decreases the dry matter accumulation, and the intensity of photosynthesis at the experimental plants, while the treatments with bio-fertilizer increased these parameters. The cadmium accumulated in the roots, the transport to the shoots was low. We came to the conclusion, that –because of the different nutrient-uptake systemthe sunflower took up more cadmium. Using bacterium containing bio-fertilizer the toxic effect of cadmium was moderated. By our experimental results the use of Phylazonit is offered under contaminated conditions.

Comparison of Integrated and Conventional Production of Young Nonbearing Apple Orchards
3-5Views:191The large number of pesticide applications in apple orchards creates serious problems with pesticide residues and their side effects on beneficial organisms, the environment and human health. This is the reason behind the search for new systems for apple protection.
The investigations were made in apple orchards of the Institute of Agriculture at Kyustendil, during the period from 1997-1999. Three scab resistant cultivars grafted on rootstocks MM106 were planted in 1996. The orchard was divided into four plots. Two plots were treated as „conventionally” and the other two were treated as „integrated” according to the general principles, rules and standards of integrated apple production.
The key disease during the experimental period was powdery mildew, which can be controlled only with pruning of infected clusters and shoots during the first three years after planting. The key pests in the orchard during the nonbearing period were the green apple aphid and San Jose scale. In the integrated plant protection system, it is possible to reduce the number of insecticide treatments depending on the density of the main pests. -
Comparison of macroelement and microelement contents of conventionally and organically grown crops
87-92Views:549Nowedays one of the most important issues to discuss is the healthy nutrition: feeding our bodies with high quality nutrients, which is free of chemical residues. The demand for healthy and nutritious food is increasing worldwide, that results in the growing popularity of consumption of organic food. Several studies dealing with the nutrient content of traditional and organic food have been published lately, since it became clear that eating food contaminated with chemical residues damage to health, food and the environment. Therefore it would be desirable to find out if organic food is really superior to conventional one. In our study we analyzed the dry matter, ash, macroelement and trace element content of organically and conventionally grown crops (carrot root, potato tuber and parsnip). Our results provide further information to consumers about the nutritional value of organic and conventional crops.

Comparison of major population parameters of Brown hare (Lepus europaeus, Pallas 1758) in two hunting fields of the Great Hungarian Plain
69-74Views:407Hungarian stock of game is not only part of our national treasure but also one of our domestic products and economic income. Not indifferent therefore the number and the state of health of our wildlife. Population decline of the Brown hare (Lepus europaeus, Pallas 1758) (one of our most important small game in Hungary) takes a long time. Demographic parameters of Brown hare was examined, particularly the factors affecting the decline of the species in Hungary. We took samples from typical habitats where the Brown hare could be found in relatively high density in our country. The article reports data of reproductive characteristics, diseases, parasites of Brown hare and other factors such as climatic and anthropogenic which could influence of the population dynamics. We mention sample collection and processing methods eg: population size estimates, examination of reproductive organs, the sex ratio and the age structure as well as the individual condition based on data of domestic and foreign authors and our partial results.

Condensed tannin content and antioxidant activity of Hungarian sorghum varieties grown at Research Institute in Karcag
155-160Views:712Cereal-based products are one of our main energy sources, and are consumed on a daily basis. One of the weaknesses of wheat based products is their low antioxidant content. Sorghum is a minor cereal, mostly consumed in Africa and Asia. Amongst other phenolic components it contains tannins, which are potent antioxidants and have other positive effect on human health, for example anti-tumor, anti-inflammatory and anti-viral/bacterial effect. We evaluated the tannin content (vanillin-HCL) and antioxidant capacity (DPPH) of sorghum varieties (Alföldi1, Zádor, Foehn, Albita, Albanus) grown in Hungary, with two type of agronomy technology.. Red varieties especially Alföldi1 and Zádor had higher tannin contents than white varieties. The highest condensed tannin content was 1470±73 mg 100g-1 (Control, Alföldi1), 1810±154 mg 100g-1 (Fertilized, Alföldi1), and the highest total antioxidant capacity was 2099±19 mg 100g-1 (Control, Alföldi1) and 2117±26 mg 100g-1 (Fertilized, Alföldi) We found that sorghum type, variety and color influence their tannin and antioxidant contents in general.

Describing Fusarium diseases on maize in 2013 using data from several production sites
60-64Views:473As in other parts of the world, the frequency of weather extremes has increased greatly in Hungary in recent years. This means that maize production is faced with greater risks from all aspects: nutrient replacement, irrigation, plant protection. This is especially true of fusarium diseases. In a continental climate, the pathogens causing the most serious problems are species belonging to the Fusarium genus. They infect the ears, which – besides reducing the yield – poses considerable risk to both human and animal health due to the mycotoxins produced by them. Depending on which Fusarium species are dominant at a given location, changes can be expected in the level of infection and in the quality deterioration caused by the mycotoxins they produce. Fusarium spp. not only damages the maize ears but when pathogen attacks the stalk, the plant dies earlier, reducing grain filling and resulting in small, light ears. In addition, the stalks break or lodge, resulting in further yield losses from ears that cannot be harvested. The degree of infection is fundamentally determined by the resistance traits of the maize hybrids, but also a great role in that region Fusarium species composition as well.

Assessing animal species at risk for SARS-CoV-2 transmission: Bioinformatic analysis based on Angiotensin-Converting-Enzyme (ACE2) homology in edible and other animals
127-137Views:515A novel coronavirus called SARS-CoV-2 was detected in December 2019, leading to the COVID-19 pandemic that began in Wuhan, China. This virus is classified as severe acute respiratory syndrome SARS-CoV-2 due to its significant similarities with the SARS-CoV virus. Initially, bats were recognized as the primary animal hosts, but later research indicated that other animals could also serve as reservoirs, posing health risks, particularly for those species consumed by humans. SARS-CoV-2 binds to the angiotensin-converting enzyme 2 (ACE2) as its cellular receptor, utilizing the receptor-binding domain (RBD) of its spike protein, much like SARS-CoV does.
The study aimed to identify animals, particularly edible animals, that may be susceptible to infection by SARS-CoV-2. This was achieved through bioinformatics techniques, including alignment analysis of genomic sequences from selected animals, identity percentages comparison, and phylogenetic analysis based on the interaction between ACE2 and the receptor-binding domain (RBD) of SARS-CoV-2. This analysis identified rabbits, donkeys, alpacas, horses, wild boars, field rats, and monkeys as potentially susceptible edible animals. Additionally, primates were highlighted due to their close genetic resemblance to humans. Overall, 22 animals worldwide were identified as susceptible, marking them as possible reservoirs and hosts for the virus, emphasizing the need for vigilance around animals that humans may contact or consume.

Búzaminták fungicid szermaradvány ellenőrzése és gombafertőzöttségének kimutatása
45-51Views:169To protect crops with chemicals against different microorganisms are very important because residues of toxins could pollute infected grains. This could have the meaning of serious danger to the human and animal health. Similarly important is knowledge of details about presence or absence of any practically applied protective compounds. Experimental studies were performed on fungicide treated cereals of the Cereal Research Non-Profit Company, Szeged. Chromatographic methods were used (GC and some GC-MS) to find low level fungicide residues, microwave-assisted isolation of ergosterol was followed by HPLC to detect possible fungal infections and a more detailed microbiological analysis completed the work. Concerning the dry year 2000, no fungicides were found in the samples (by November), the ergosterol level was found to be less than 8 ppm, meaning good quality, coupled with an extremely low level of fungal infections. This was confirmed by direct microbiological testing. In comparison with the microbiological results from 1999, a negative difference can be recognized, most probably due to the rainy weather throughout the year.

Arrival of invasive pests in our direct environment and control opportunities
23-26Views:343The author refers about the nowadays applied practical plant protection activities against pests occuring on trees, shrubs and turfs of public domains. It is overviewed those insects, diseases and weeds which cause damages and touched also upon disturbing the local residents only and tasks to the plant protection engineer expert to manage them. Among the special features of public domains should be mentioned that the rules are difficult to harmonize according to the legal, public health, and horticulture requirements at the same time. The anti-pesticide attitude of EU and the modest range of pesticides which are applicable on public domains make difficulties in optimal management work. The author draws up proposals how to manage the complex plant protection on public domains.

The importance of selenium in the living world and in the scientific research
278-286Views:727Presently, selenium (Se) is one of the most investigated microelements. It has an important proven role in many vital processes. Directly or indirectly, selenium deficiency can play a role in the development of many diseases. On the other hand, the concentration range in which selenium is essential is narrow; there is a narrow gap between necessary and toxic content in dietary intake. In this context, selenium contamination poses a further health risk for people if they live near the industrial areas and mining activity.
In this paper, we comprehensively introduce the very important trace element selenium. We studied the base parameters, deposit, analytic and deficiencies, problem of contamination and also the solution of contamination problems of selenium. -

Application of yeasts fortified with microelements – Review
101-106Views:260Microelements 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. -
Dieback of apricot plantations caused by 'Ca. Phytoplasma prunorum' in Borsod-Abaúj-Zemplén county (Northern-Hungary)
34-41Views:323Plant diseases caused by phytoplasmas have increasing importance in all over the world for fruit growers. Lately, phytoplasma diseases occur on many fruit varieties and responsible for serious losses both in quality and quantity of fruit production. In the long-run these diseases cause destruction of fruit trees. The apricot phytoplasma disease (Ca. Phytoplasma prunorum) was first reported in Europe in 1924 from France. In 1992 the disease has also been identified in Hungary. On the base of growers' signals serious damages of "Candidatus Phytoplasma prunorum" Seemüller and Schneider, 2004 (formerly: European stone fruit yellows phytoplasma) could be observed in different stone fruit plantations in the famous apricot-growing area nearby Gönc town, Northern-Hungary. Field examinations have been begun in 2009 in several stone fruit plantations in Borsod-Abaúj-Zemplén County mainly in Gönc region which is one of the most important apricot growing regions in Hungary, named “Gönc Apricot Growing Area”. Our goals were to diagnose the occurrence of Ca. Phytoplasma prunorum on stone fruits (especially on apricot) in the North-Hungarian growing areas by visual diagnostics and confirm data by laboratory PCR-based examinations. All the 28 collected samples were tested in laboratory trials and at 13 samples from apricot, peach, sour cherry and wild plum were confirmed the presence of phytoplasma (ESFY). On the base of observations it seems evident that the notable losses caused by "Ca. Phytoplasma prunorum" is a new plant health problem to manage for fruit growers, especially apricot producers in Hungary.

The effects of education, culture, research and development in Hajdú-Bihar county
87-90Views:583The most important instrument of social advancement and economic development is the education system. The educational qualification of the population of Hajdú-Bihar county is continuously improving, however the census data of the year 2001 show that the educational qualification of the population of the county did not reach the national average. The educational qualification of the county’s population is higher at the county seat and in other cities and lower in small municipalities. The county’s ratio is strongly influenced by the data of the county seat Debrecen and that of Hajdúszoboszló sub region.
The unfavorable educational level of the region is related to the migration tendencies and the brain-draining trends of the past decades, as a consequence of which the population of the less developed eastern regions has moved either to the capital, or to the county seats, or larger cities of the region. The young are increasingly affected by the process.
The number of kindergartens in the county corresponds to the national average, therefore taking into consideration the regional demographic characteristics the aim should be the equalization of regional disproportions. The number of students per 1000 resident within the Northern Great Plain Region and in the county significantly exceeds the national average. The secondary school network of the county consists of 38 secondary grammar- and 51 secondary vocational schools.
The secondary schools of Debrecen have considerable impact on the county’s secondary education. The vocational training network of Hajdú-Bihar county is a large, in its conditions highly differentiated institutional network in which all types of secondary vocational institutions are present with secondary technical-, vocational-, accredited higher vocational-, specialized or preparatory vocational-, and special skill enhancement programmes. The majority of the secondary institutions have regional, rarely national enrollment.
Students who have the intention to continue their studies in higher education within the county can study in Debrecen or Hajdúböszörmény.
The integrated University of Debrecen has the highest student number within the country and it offers the widest range of academic programmes in Hungarian higher education. The University of Debrecen with the wide range of graduate and postgraduate educational programmes, unified academic qualification system, English language programmes is a European standard scientific centre of the Trans-Tisza Region. The county’s higher education takes exceeding share beyond its weight in the education of Natural Sciences (Biology, Physics, Chemistry, Earth Sciences, Mathematics), Health- and Social Sciences, Agricultural- and Environmental Sciences and Information Technology, which positively influences its educational structure. The county’s share in the education of Humanities (Hungarian Language, Foreign Languages, History, Archeology, Philosophy) is also significant.
6.3% of the country’s scientific researchers work in the county. In 2010 7.0% of the country’s R+D expenditure was spent here. 3/4 of the region’s research capacity is in Hajdú-Bihar county employed either by the University of Debrecen or by the research teams of the Hungarian Academy of Sciences.

The bioactive compounds of sour cherry (Prunus cerasus) with special regards to antioxidant activity and antioxidant density
83-87Views:593Evidence suggests that a diet high in fruits and vegetables may reduce the risk of chronic diseases, such as cardiovascular disease and cancer, and phytochemicals including phenolics, flavonoids and carotenoids from fruits and vegetables may play a key role in reducing chronic disease risk. Recent research has proven that sour cherry (Prunus cerasus L.) is a valuable natural source of some bioactive compounds important in human health preservation.
In our work, we identified the total antioxidant capacity and ”antioxidant density” of sour cherry varieties named ”Újfehértói fürtös”, ”Debreceni bõtermõ”, ”Kántorjánosi” and ”Érdi bõtermõ” and those of the ”Bosnyák” sour cherry clones. ”Antioxidant density” is a biological value indicator obtained in a synthetic way, which indicates the antioxidant capacity of the particular food, e. g. fruit and vegetable, per 1 Calorie. -
Study of animal welfare status in dairy cow herds in Hungary – looking for causes of lameness
47-50Views:391In 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.

Leaf and root evaluation of bioactive compounds of different beetroot varieties
135-139Views:406The importance of beetroot lies in the numerous health benefits, attributed to its wide-ranging array of minerals, vitamins and bioactive compounds which play a key role in the human diet. Generally, beetroot is consumed for its root, however, its leaves also contain a good amount of bioactive compounds. The experiment was carried out with four beetroot varieties in order to compare the amount of bioactive compounds in the root and the leaf. The analyzed data were total dry matter content, total polyphenol, flavonoid and vitamin C.Results have shown that roots contain the highest amount of bioactive compounds. Nevertheless, leaves can be also considered a significant source. Therefore, consumption of the young leaves is highly recommended due to their availability after thinning or at maturity stage (60 days after the germination). Of the examined varieties, ‘Libero’ demonstrated the highest total polyphenol, flavonoid and vitamin C values, although it was found to be statistically insignificant. -
The effect of diet composition, a probiotic and a symbiotic treatment on the ileal microbiota composition of one-week-old broiler chickens
213-220Views:332A healthy microbiota present in the small intestine contributes significantly to small intestinal function, including digestion, nutrient absorption and health. The current study investigated the effects of a prebiotic, a probiotic and a symbiotic supplementation on ileal microbiota composition of broilers at 7 days of age. In a total of 574 male Ross 308 day-old chickens were divided into four groups using six replicate pens and 24 chickens per pen. A maise-soybean based control diet (C), a control diet supplemented with probiotics (Broilact; Br), a control diet supplemented with symbiotic (inulin, yeast, Bacillus subtilis; Sy) and a wheat based diet supplemented with wheat bran (W) were formulated. On day 7 of life, two chickens per pen were slaughtered and ileal chymus samples were collected. For microbiota analysis 16S rRNA (V3-V4 region) gene targeted Illumina MiSeq sequencing was used. Feeding all diets supplemented increased the diversity to varying degrees compared to the control (C) diet (p=0.006). As a conclusion, all supplementation substantially influenced ileal microbiota of broiler chickens at an early age. All these results could offer some information for the future study on the relationship between early intestinal microbiota and the compounds of the feed.

The effect of heat treatment on the antioxidant activity of sour cherry jams
121-126Views:598Sour cherry (Prunus cerasus) is a valuable fruit known for its high antioxidant content. Its bioactive substances contribute to health maintenance, as they have strong anti-inflammatory and free radical scavenging properties. Jams made from sour cherries provide a concentrated form of the antioxidant content of fruit, thus can play an important role in a balanced diet. Heat treatment is an essential part of the jam-making process, as it ensures the microbiological stability and longer shelf life of the product. At the same time, heat can significantly affect the antioxidant content of the fruit. In this study, the authors compared the antioxidant content of six different sour cherry jams. Based on the obtained results, it was concluded that the fruit content of sour cherry jams alone is not sufficient to estimate their antioxidant capacity, but the extent of the effect of heat treatment on it is generally independent of the nature of the products. This result highlights that the fruit content and the applied technology play an important role in preserving the antioxidant content of fruits during product processing.

Study of traditional folk foods from the point of view of nutrition in Hajdú-Bihar County
47-51Views:465Healthy nutrition is one of the major topics of our days. The occurrence of the so called “civilization diseases” is increasing continuously as a result of the changes in our nutritional habits and life-style. It was thought that folk nutrition at the beginning of the 19. Century had several beneficial effects on health. For this reason it was decided to study the food and nutritional habits of the population of Hajdu-Bihar County around the 1930s on the
basis of literary sources to see how well they do match with modern requirements of healthy nutrition. -
Dietary fibre prevalence and its role in human nutrition
9-13Views:455The role of dietary fibre and its impact on health is increasing. It is worth noting that their beneficial effects on the body are becoming more widely known, but their consumption is still below the recommended daily intake from food. Dietary fibre, as a class of compounds, includes a mixture of plant carbohydrate polymers, both oligosaccharides and polysaccharides. Dietary fibre has been linked to a number of diseases, as its consumption can reduce the risk of cardiovascular disease and type 2 diabetes. They influence the composition of the bacteria present in the human gut. Consuming the right quantity and quality of dietary fibre can play a role in the prevention of certain types of cancer. Nowadays, it is common to produce various fibre-enriched foods, called functional foods, because of the beneficial effects they have previously had on the body. In the present work we want to give a general description of dietary fibre and its role in the body.

Coherence and connection between the good pond culture practice and the environment conscious management
60-73Views:191According 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). -
The factors affecting the proliferation of mould fungi and mycotoxin production during the storage of wheat and the identification methods of the appearing branches
129-133Views:253Nowadays, it is often suggested that, we should eat products made with whole grain cereals, despite of the fact that it raises the risk of consuming wheat products infected by mold and their toxins originated from the plough-lands and the stocks.
Two third of the cultivated fields in Hungary are planted with cereals. The most alarming problem for food and feed security is caused by the Fusarium species. The greatest problem of all is caused by the mycotoxins. When they get into the food chain they can be a serious threat to public health. In addition, we have to face up to the problem of the effects of global warming that influence the growth of microbial infections in different ways.
In this article we tried to summarize the effect of climate change on molds, the factors which have effect on growing and mycotoxin producing of molds and the identification methods of molds. -
Comparison of the physiological responses of an oil-pumpkin cultivar and hybrid under different nitrogen supply conditions
65-69Views:493Cucurbita pepo var. styriaca is known as a medicinal crop among other cucurbits. The benefits of cucurbits fruits are very important in terms of human health, purification of blood, removal of constipation, digestion and supplying energy. The mutant styrian oil-pumpkin (Cucurbita pepo L. convar. Pepo var. styriaca Greb.) exposes a complete lack of lignification of the seed testa. For this reason, this kind of naked pumpkin seed is more consumable as snack than other seeds. The vegetative growth of plants is crucial for fruit production. Nitrogen is the most imperative element for the proper vegetative growth and development of plants which significantly increases and enhances yield and its quality by playing a vital role in the biochemical and physiological functions of plants.
Field studies were conducted to study the effect of nitrogen nutrition on certain physiological parameters and their differences between the styrian oil pumpkin hybrid and cultivar (Gleisdorfi Classic cultivar and GL Rustical hybrid). The small block experiment was carried out based on a factorial experiment with a completely randomised block design and four replications in the Research Institute of Nyíregyháza during the summer period of 2017 and 2018. Three different concentrations of nitrogen fertiliser was applied at sowing. Photosynthetic pigments (chlorophyll-a, -b and carotenoids) were analysed as one of the basic factor of efficient photosynthesis. The yields of two genotypes were also measured in all treatments as seed-weight. The contents of photosynthetic pigments were higher in the oil-pumpkin hybrid, mainly the carotenoids in 2018. The vegetation period of 2018 was drier than in 2017, the hybrid oil-pupmkin was more efficient in stress tolerance than the cultivar with higher carotenoids pool. The obtained yield was more pronounced in the oil-pumpkin hybrid than the cultivar in all examined years. The hybrid GL Rustical was more sensitive to nitrogen treatment than the cultivar Gleisdorfi Classic.

Effect of using antioxidants as feed additives in the diet of dairy cows on the vitamin E and lycopene content of milk
69-72Views:370In 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.
