The role of animal breeding with special regard to native pigs of food supply and rural development in Laos
149-154Views:432The present paper explored the influence of breeding native pigs on livelihood conditions and the contribution of native pigs to the rural development and rural poverty reduction in the rural areas of Lao PDR. Pig production plays an important role in meat supply for both urban and rural areas of Laos. It is clear that most of the pig products in the country come from smallholder pig farms, and more than 90 percent of those products are the native pigs mostly raised by farmers in remote areas. In general, livestock production distributed between 15–18 percent to GDP, while most of animal production still remains as the traditional methods. Rural development is always the first priority of the Laos government since its independence in 1975, however, the poverty rate in rural areas remained high at 23% in 2018. It might block the development goal of the government which will lead the country out of the least development status by 2020. The food security and malnutrition in the rural or mountainous areas are considered as the majority issue that both government and several international organizations have been thriving hard to overcome, which researchers showed that more than 45% of children under 5 years of age were stunted, and 28% of them were underweight. Inspired of more than 50 % of the households in the rural areas of Laos reported they consumed chicken and pork at least one day a week. While native pigs play an important role on meat supply, it also constituted around 9–14 % of annual income of the households in rural areas. Therefore, the increase the production of pigs and poultry is one option to promote the meat supply to households in the rural areas of Laos. This paper will be a pathway to guide and identify for the final decision to what experiment will be implemented on Lao native pig in Laos (2021–2023) to complete the comparative study on reproductive physiology and reproductive management methods of Hungarian and Lao Indigenous pig breed. Which found it still needs further afford to research and improve more about native pig performance for all areas of productive and quality management.

Investigating the potential for dual-purpose use in winter oats
35-42Views:467Dual-purpose usage is not a common technology for oats in Hungary, which is not surprising, as the area sown to our main crop is also very low. Yet the crop has a lot of untapped potential, not to mention its excellent nutritional parameters. In our experiment we investigated how much biomass can be expected after mowing winter oats at different phenological stages and whether we can expect a valuable grain yield after this process. Mowing was carried out at one-week intervals on a total of 4 occasions with 2 cutting heights. Plant height and NDVI values of the vegetation in the plots were measured during the experiment. After the harvest of the fully ripened grains, the yield and the thousand kernel weight (TKW) were determined. Our results show that with a lower cutting height (6 cm), a higher biomass yield can be achieved. The cutting height had no statistically verifiable effect on either NDVI or plant height. Droughty weather conditions during subsequent mowing significantly reduced the regeneration capacity of the plants, which was strongly reflected in the measured parameters. Furthermore, a higher grain yield was measured at a cutting height of 9 cm, which decreased gradually with the mowing time. Neither the cutting height nor the mowing time had any effect on the TKW.

Presence, feeding and health status of collared doves (Streptopelia decaocto Friv. 1838) on animal breeding farms
49-54Views:310In 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. -
Advancement of a Common Wheat (Triticum aestivum L.) Selection System
8-11Views:198All the research in Hungary and other countries in Europe focus on improving the quality of crops and increasing the competitiveness of production.
In this respect, we have to advance the conventional technological elements, reduce the application of pesticides and fertilizers, and produce new varieties suitable for environmentally-sound production. In our crop breeding programs, we applied conventional and biotechnological methods (embryo rescue and double haploid methods) in order to get somaclonal and gametoclonal variations.
We produced winter wheat lines (HP-31-95, HP-82-96) by traditional way, which have high baking qualities and high nutrient efficiency. Some diseases can limit the quantity and quality of a wheat crop. We examined several wheat diseases in our winter wheat candidates, and we found that our progenies have resistance to leaf rust.
With respect to a serious problem was the small quantity of applied fertilizers and the other externals, our research focused onto advance a common wheat selection system, with the help of it, we can handle these problems. We have summarized that our selected progenies can compete with the registered varieties with quality and environmental respect. -
Micropropagation of Leuce-poplar clones and its role in selection breeding
43-48Views:370Leuce-poplars (mostly white poplar and its natural hybrid grey poplar) are native tree species trough Hungary. They are covering more than 4.0 per cent of the Hungarian forested area (77 000 ha). The white (grey) poplars play a significant role in the forestation under sandy soil site conditions as well as they are of importance from nature conservation point of view as well.Long-term selection breeding work is going on at the National Agricultural Research and Innovation Centre Forest Research Institute (NARIC FRI), involving selection of fast-growing Leuce-poplar clones under dry site conditions.Micropropagation technology is relatively quickly spreading in forestry. In vitro multiplication of trees is applied mainly in fruit growing in Hungary, in case of forestry it is used mainly for selection breeding.This paper presents a short overview on the micropropagation trials with different Leuce-poplar clones and the early evaluation of the seedlings growing of the micropropagated clones/varieties. -
Upgrading breeding value estimation in beef cattle
451-458Views:371This paper gives a summary of the possibility for applying genomic information for breeding value estimation in beef cattle breeding. This process is called genomic prediction and is now widely used in dairy cattle globally as well as in some beef and sheep populations. The advantage of genomic prediction is a more accurate estimate of the genetic merit of an individual at a young age thereby facilitating greater annual genetic gain, predominantly through shorter generation intervals. Genomic predictions are more advantageous for sex-linked (e.g., milk yield), low heritability (e.g., fertility) and difficult-to-measure (e.g., feed intake) traits. The larger the reference population, on average, the more accurate the genomic predictions; additionally, the closer genetically the reference population is to the candidate population, the greater the accuracy of genomic predictions. Research is continuing on strategies to generate accurate genomic predictions using a reference population consisting of multiple breeds (and crossbred). Retrospective analysis of real-life data where genomic predictions have been operation for several years clearly shows a benefit of this technology.

Seedling morphology of different wheat genotypes at early stages under hydrocultural conditions
249-254Views:474Consuming “sprouted seeds” is one of the most important factors of a healthy diet. An experiment was conducted in the University of Debrecen, Research Centre of Nyíregyháza (Hungary) in 2014 to analyse some morphological traits of four winter wheat genotypes (Triticum aestivum L.) and one spelt (T. spelta) variety. Our results showed that the spelt wheat variety “Franckenkorn” could maintain higher root length throughout the experimental period. On average, both “Perbetei” and “Franckenkorn” varieties could maintain higher root number compared to the other varieties. The extensive breeding line “1401 HK” had the highest shoot length throughout the whole experiment, being significantly higher than the landrace variety “Perbetei” and both of the varieties “KG Bendegúz” and “KG Kunhalom”. It could be concluded that “KG Bendegúz” cultivar and “Perbetei” landrace seem to be the most suitable for aquaculture techniques. In addition, “1401 HK” breeding line can be the most suitable for the production of juice since the minimal required shoot length (12 cm) was achieved within the shortest period of time after sowing (9 days). This breeding line and “Franckenkorn” can also be suitable for production of “wheatgrass”, because it is consumed without roots. Further research is needed to evaluate nutritional values of these genotypes.

Random regression models for genetic evaluation of performance of the Hungarian show-jumping horse population
87-91Views:415The aim of the study was to estimate genetic parameters for show-jumping competition performance using random regression model. Show-jumping competition results collected between 1996 and 2009 were analyzed. The database contained 272 951 starts of 8020 horses. Identity number and gender of the horse, rider, competition date, the level of the competition and placing were recorded in the database. Competition levels were categorized into five groups. Weighted – competition level used – square root transformed placing was used to measure performance of horses. The random regression model included fixed effects for gender, year and place of competition, and random effects for rider, animal and permanent environment.
Later performance of show-jumping horses measured with weighted square root ranks is less influenced by rider and permanent environmental effects than performance at the beginning of a horse’s sporting career. Heritability increased continuously from 6.3 years of age (2296 age in days), values were in the range of 0.07 and 0.37. Higher heritability was found in later ages. Weak genetic and phenotypic correlation was found between the early 4–5–6 years of age and older (7, 8, 8+) age classes. From 8.5 years of age (3132 days old) there were strong genetic and phenotypic correlations between neighboring age groups. For the same age classes moderate and strong genetic and phenotypic correlation was found. Genetic correlation between 13.5 years of age and older horses was very strong.

Economic impacts of applying EU animal protection regulations in hog breeding farms
76-80Views:302Hungary’s intention to join the EU makes it necessary to adopt, introduce and use the EU system of law. In Hungary, the legal control of animal welfare has improved (XXVIIIth law in 1998); however, most of our pig farms do not meet the EU animal welfare law requirements for some reason. We examined 9 pig farms in Hajdú-Bihar, Borsod-Abaúj-Zemplén and Heves counties. We chose those farms which use the combined breeding
technology most frequently used in Hungary. The most important part of the welfare directive is the definition of the minimum space per animal. We analysed the data in comparison with EU laws. On the basis of the analysis, it can be said that there is a narrow cross-section: the breeding of piglets. During the cost analysis, we analysed cost and highlighted the permanent cost. We studied how these costs would change if EU animal welfare laws were observed. We also examined the specific data per 1 sow and per 1 kilogram of slaughter pig. We compared the present data (1999) with those we get if EU animal welfare laws concerning minimal space per pig were now followed. It can be stated that after decreasing the sow live-stock in accordance with EU directives, the permanent cost would increase by 17,7% per sow. If the required space per sow were provided, the total cost per sow would increase by 1,9% from 421,1 thousand forints to 429 thousand forints, on average. This would mean a decrease of 7,9
thousand forints profit per sow. As with the decrease of the number of sows, the number of slaughter pigs also decreases. Total cost per 1 kg of slaughter pig would increase from 214,7 forints to 218,2 on average. -
The effect of foreign stallions on the Hungarian Furioso-North Star breed
67-70Views:569The most common aim of animal conservation programs is to maintain genetic diversity. Furioso-North Star is an indigenous Hungarian horse breed originated from Mezőhegyes Stud. The breed is based on two founder stallions, Furioso Senior and North Star Senior. The aim of this research study was to analyze the effect of the foreign breeding stallions to the genetic structure of Hungarian Furioso-North Star breed. The genetic structure of the breed was studied from pedigree data what was received from the Furioso-North Star Horse Breeding Association. Foals born between 2015–2018 were chosen as reference population. Every breeding stallion was marked by nationality (Austrian, Czech, German, Hungarian, Romanian or Slovak) according to their birth place. The population was described with genetic variability, what was calculated using Endog software. The Furioso-North Star breed is popular in Central Europe and nearby countries. The stallion imports and the stallion transfers were necessary and useful as they made changes in the composition of the genetic variability. The new genes and the new lines have refreshed the genetic structure. There were several breeds, like the Nonius, Shagya Arabian and English Thoroughbred, whose had an impact on the genetic structure of the Furioso-North Star breed.

Investigation of the Resistance Against the Fusarium solani at Different Pea Varieties and Combinations of Breeding
157-160Views:129The Fusarium species are soil and polyphage parasits, and the rate of damage, caused by them, highly depend on interactions between climatic and edaphic factors and also on sensitivity of cultivars. Even though about 70-80 percent of the widely grown green peas cultivars is resistant to Fusarium oxysporum f. sp. pisi 1. race, the rate of Fusarium infections and severity of symptoms increased in the latest years. It is supposed that another Fusarium sp. the Fusarium solani has been spreading. The most exact way to study the cultivars in a provoking garden established in natural environment, where the pathogen is artificially enriched to a level, at which the cultivars can be distinguished according to their susceptibility. In the provoking garden the reaction against to Fusarium of our breeding lines and our registered cultivars and cultivars existed on the National List (including cultivars with well-known susceptibility as standards) are examined year by year. In our experiments we could found two green peas cultivars to be resistant to Fusarium solani (Early sweet (13,36%) and Lora (16,9%)) The breeding lines Margit and 8607/75-3-2 proved to be the most susceptible to Fusarium solani (94,4% and 73,1% infected plants, respectively).

The methodology of the Hooded Crow’s (Corvus cornix L.) colour ringing and the previous results
43-48Views:366The Hooded Crow (CorvuscornixL.) have moved in several Hungarian cities in the last few decades. It is breeding in Debrecen since 1959, and nowdays it’s presence can be detected at all points of the city, it is an permanent breeding species of the bird fauna. Our knowledge about the nature of urban races, including motion patterns, area fidelity is sufficiently incomplete. The aim of our research is to answer these questions by using our colour-ring program. In this study we present in details the methodology of Hooded Crow’s colour-ring program in urban area, and we also report our previous
achievements. -
A review on the trend of livestock breeds in Laos
227-237Views:703When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still the critical component of animal breeding in Laos. Thus, there is a need to review the previous, current situation and prospects for Laos' livestock production. It aimed to study the different traits among the existing dominant local and improved livestock breeds (cattle, pig, and goat) and a more in-depth study on the livestock sector's previous evolving and prospects. Our findings revealed that the general trend of livestock population in Laos increased year-by-year for over 45 years, except for 1995 to 2000. It was decreased by almost 22% due to the new national strategy on economic revolution. The first foreign breeds were introduced into Laos, i.e., Large White, Landrace, and Duroc in 1980, Red Sindhi bulls in 1998, the frozen semen of Red Brahman 2003, and Bach Thao goats between 2001 to 2003. Unfortunately, many data are still not precise for introducing other foreign breeds like Boer goats, Thai Grey and Red Brahman. There were many missing data on the improvement of livestock breeds in Laos, including the local and improved breeds' reproductive and productive performance, which needs more study and research. We conclude that the semi-complex farm operation should be applied to improve livestock breeding and their productions in Laos.

Yearly change of Wheat dwarf virus infection rate during 1996-2010 in winter barley
22-28Views:199Yearly change of the infection of Wheat dwarf virus was studied in winter barley during 1996-2010. Surveys were carried out at Kompolt (Rudolf Fleischmann Research Institute, Róbert Károly College), in winter barley breeding lines showing leaf yellowing and stunting symptoms. In 1996, 250 winter barley samples were tested. During the period of 1997–2005, 100 samples were collected in each year. In 2006, 490 winter barley samples were tested. In 2007 and 2008 the number of samples collected was 500 from winter barley. In 2009 year 100, and in 2010 year 100 winter barley samples were collected for virus testing. Virus diagnosis was carried out using DASELISA for the detection of Wheat dwarf virus (WDV), Barley yellow dwarf viruses (BYDV-MAV, BYDV-PAV, BYDV-RMV, BYDV-SGV), and Cereal yellow dwarf virus (CYDV-RPV). During the ten of the last fifteen years, the occurrence of Wheat dwarf virus in infected samples exceeded those of other viruses causing leaf yellowing and dwarfing symptoms. There were years (1997, 2002, 2004, 2007, 2009 and 2010) when only the Wheat dwarf virus played the main role in development of yirus symtoms. A contrasting tendency can be observed between the degrees of infection of WDV and BYDV. With a rise of infection in the WDV, the proportion of BYDV decreased and vice-versa.

Industrial Utilization of Grasses
131-134Views:159The Agricultural Research and Development Institute P.U.C., Szarvas – realizing the importance of using the biomass in a number of ways – was one of the first in Europe, who began the breeding of grasses suitable for industrial utilization. The possible areas of using the energygrass – which could be called industrial grass – are the following:
– Energetical use
– Paper industry use
– Utilization as an industrial fibrematerial
– Use for feeding
The aim of the breeding programme: developing the kinds of grass, which yields big drymaterial mass and suitable for industrial utilization. These kind of grass, taking soil-utilization, economicality and environmental protection, offer and ensure new marketing perspectives and employment facilities for the disadvantageous areas. -
The effect of feeding different glycerol sources on the performance of lactating sows
99-103Views:315Glycerol is a by-product of the biodiesel industry and it might be a good alternative to moderate the energy deficiency of sows during the lactation period. Preliminary experiments were carried out to test the effect of a powder, solid based “food grade” glycerol source with 72.9% glycerol content (Trial 1) and a liquid “feed grade” glycerol source with 86% glycerol content (Trial 2) on the performance of lactating sows and their litters. Trial 1 was conducted with 5 Hungarian Large White×Hungarian Landrace sows/treatment (313±24.9 kg) and Trial 2 with 12–12 DanAvl (323±17.0 kg) sows and their litters/treatment. Neither the solid, powder based glycerol (Trial 1), nor the liquid glycerol source (Trial 2) had significant effect on the feed intake, reduction in live weight and back-fat thickness, and weaning-tooestrus interval (p>0.05) of lactating sows. In Trial 2, on the 14th, 21st and 27th days of lactation the milk samples were collected and it was found that 50 kg/t glycerol decreased the protein content of milk samples (p<0.05). Glycerol supplementation had no effect on dry matter, fat, lactose content of milk samples (p>0.05). In Trial 2, no significant difference was found between control and experimental sow groups in triglyceride concentration of blood samples and in the activity of liver enzymes (ALT, AST, GGT; p>0.05), but the concentration of plasma glucose and cholesterol increased tendentiously (p<0.10).
Based on our preliminary results, it can be concluded that additional dose trials are needed to perform in order to study the effect of glycerol supplement on milk production and on metabolic processes of lactating sows.

Effect of the claw disorders on production performance in dairy cattle
15-19Views:323The aim of the study was the influence of claw disorders on production traits in dairy cattle. Observed were claw traits as claw angle, claw length, heel index, claw height, claw diagonal and claw width. Right hind claw after functional trimming was evaluated. Occurrence of claw disorders like interdigital dermatitis and heel erosion (IDHE), digital dermatitis (DD) and sole ulcer (SV) as well as the progress of disease were observed. Basic summary and variation statistics was performed by the SAS software. Two herds were included in the study. Holstein dairy cows (n=101) produced 11 875 kg of milk, 468 kg (3.94%) of fat and 396 kg (3.34%) of proteins. Holstein cows were affected with IDHE in 22 cases, with DD in 6 cases and with sole ulcer in 10 cases. Slovak Simmental dairy cows (n=101) produced 5834 kg of milk, 258 kg (4.44%) of fat and 209 kg (3.59%) of proteins. Slovak Simmental cows were affected with IDHE in 8 cases, with DD in 5 cases and with sole ulcer in 19 cases. Observed was that claw disorders caused deviations of milk production.

‘Kindergarten’ keeping-system in farrowing house: effect the socialization of piglets on weight performances, fecal cortisol metabolite level and post-weaning behavior
167-174Views:446This study aimed to examine whether litters’ let-together system before weaning (‘kindergarten-system’) has any stress effect and effect on post-weaning behavior, respectively. One week before weaning piglets were socialized by removing four adjacent farrowing crate walls. After weaning, piglets from the same experimental groups were housed in the same rearing crates. The piglet’s body weight was measured at birth than weekly till the 7th life-week. Fecal cortisol metabolites were measured for evaluation of the adrenocortical activity. Personal observation and evaluation were carried out for behavioral analyses after weaning. There were no significant differences in weight development and cortisol metabolite levels between the control and experimental groups. Behavioral analysis showed that pigs grow up in a socialized system, rapidly evolve ranking in the rearing crates, and the self-maintenance and social behavior were more pronounced. In control groups, the activity involving movement (exploring, walking, and running) was much more decisive. Recent work suggested the beneficial effect of the ‘kindergarten’ system in the farrowing house in animal welfare aspects.

The examination of the agronomy, the amount of yield, and the yield stability of winter wheat varieties
61-72Views:236Our research was carried out at University of Debrecen Centre for Agricultural Sciences Faculty of Agriculture Institution of Plant Sciences Látókép Research Institute through the breeding year of 2003/2004, 2004/2005 and 2005/2006 using cherrnozem soil. In our research we tested 14 chosen autumn wheat varieties during the three crop years.
The different varieties showed very dissimilar ability of resistance against diseases through the three crop years. We could observe both susceptible and resistant varieties. Susceptible varieties got diseases even in favourable crop years. The observed winter wheat varieties showed higher susceptibility against helminthosporium (21.8%) and leaf rost (16.4%). Among the 14 varieties we experienced the least susceptibility in the case of ‘Gaspard’ and ‘GK Kalász’. The research showed that the disease of fusarium undoubtedly depends on the features of the crop year.
In terms of stem solidity we experienced big differences. Among all the observed winter wheat varieties the mid-late ripening ‘Gaspard’ showed the best results in the average of the three years, only 5.3% was beaten down.
The three ripening group of the winter wheat showed the following average yield in the average of three years: 7065 kg/hectare (early ripening varieties), 7261 kg/hectare (late ripening varieties), 6793 kg/hectare (mid-late ripening varieties). Among all the observed varieties the early ripening ‘Flori 2’ produced the biggest yield (7692 kg/hectare).
During the three crop years we reached very different amounts of yield which means that weather conditions had a telling affect on yield. In 2004 we reached an excellent average yield in all the tree breeding groups because of the favourable weather conditions. In 2005 we had a moderate amount of yield because of the unfavourable weather conditions of winter. The year of 2006 showed the smallest amount of yield which is due to the fact that the plant grew less thick than usually.
There were significant differences among the observed varieties in the term of yield, which can be attributed to dissimilar biological basics.
One of he most important questions is the yield stability of the varieties. We had extremely different results at this field. Speaking in general terms we can state that both weather conditions and genetical abilities have a determining effect on yield. In the case of winter wheat varieties the rate of yield fluctuation was quite big, moving in the interval of 33.7-70.3%. Among all the observed varieties ‘Gaspard’ showed the best yield stability (33.3%). -
The initial steps of the black grouse repatriation
63-68Views:290The black grouse in Hungary is an extinct but a native and protected species now. In the 19th century, they used to be common in the so called Nyírség, the North-Eastern part of the Hungarian Great Plains.
The project to re-patriate black grouse was started in 2005 by the Nyírség Company of Forestry. We studied the conditions of keeping and breeding black grouse from German and English specialists and we endeavoured to expand our breeding population in 2007.
We also started to make a database of the whole bird stock, containing biometrical data from every individual specimen and data about the eggs (weight, length, width) and nestlings (weekly weight growth). In the future, we will continue our work to breed black grouse and re-patriate the new offspring, which will be nearby wild populations in a similar bio-geographic environment. In a few years it is hoped we will be able to accomplish a wild population in a natural habitat. Our work is now to breed these birds in captivity – similar to their natural habitat – prior to their release into the wild, in order to preserve biodiversity for our descendants through re-patriating black grouse here in Hungary as well. -
Presentation of sales price reserves for live lamb
37-45Views:202Although sheep breeding in Hungary is grounded in strong traditions, its activities only comprise 1% of the total production value generated from agriculture, and 2% of that for animal-based products. The most significant portion of incomes earned in the Hungarian sheep sector has, for years now, stemmed from the sale of live animals. The sector is decidedly export-oriented, as the domestic demand for its main product, i.e. lamb meat, and is minimal, equaling some 20-30dkg per person per year. Part of the sold animals is sold to market as dairy sheep, while the greater
part is sold in the category of lamb carcasses. For this reason, the average weight of slaughter sheep has lied between 19-22 kg for years now. The target markets for live lamb sales are predominately Italy and Greece. In Greece, movement on this market has shown an upward tendency in recent years; noteworthy are also sales to Austria, Holland, Bosnia-Herzegovina and Poland. In 2003, we exported sheep meat in the form of carcasses to Italy, as well as to Germany, and of these exports, 94% went to Italy, while the remaining 6% went to Germany.
Among sheep products, only the trade balance for live animal sales is positive. But even for such producers, only those who are specialized in intensive breeding and those sheep farms “targeting” meat production can obtain earnings. Specialized literature on the sector argues that the quality of Hungarian lamb has diminished dramatically and is beginning to lose its market position. If Hungarian lamb does not meet market expectations, then it will only be bought from producers at lower prices.
My research focuses on those factors which influence price. I separately discuss the question of quality, as one of the most important decisive factors on price. Within this discussion, I describe the market expectations which actually have an effect on the acceptance of live animals for sale on commission. In practice, after the problems of quality, the next most important question is that of when sale is made. In the course of my research, I studied the development of averages for sales on commission of live lambs using statistical methods. The most important problem of this sector is the hierarchical system used in sales: this is the topic hich neither the producer, nor the buyer, wish to discuss, not even with each other. On the basis of the information at my disposal, I outlined the levels of traders and individual levels used to arrive at commission prices. Finally, I examined the components of the production value of live lamb sales. The results I obtained quantified the key role of the prices and the yield, as well as the factors influencing income. -
Examination of the impact of ecological and agrotechnical factors in a maize fertilisation experiment
13-17Views:225The year 2013 was rather extreme breeding year because of the uneven distribution of precipitaion and the summer heat. The experiment was set on with eight different genetic characteristics maize hybrids in 2013. In our study were included different kind of breeding season hybrids. We studied the effect of NKP fertilization and row spacing on the yield. The fertilizer doses are based on 25-year long-term experiment. Compared to control, the N40+PK treatment has also achieved a significant yield increase, although some hybrid of increasing fertilizer doses yield response to loss. The majority of hybrids reached higher yields using the 50 cm row spacing. The water release of hybrids was measured between 21th August and 17th September weekly, at the same time points. The rainy September slowed ripening hybrids and water release, so the grain wet content at harvest showed higher values.

Evaluation of egg quality parameters of two Hungarian ostrich populations
51-57Views:509The aim of our study was to evaluate the quality parameters, porosity and weight loss of eggs deriving from the two most significant ostrich farms in Hungary. Quality parameters included weight, length, width, shape index, egg volume, surface area, circumference and shell volume. The effect of storage conditions in both farms and the incubation technology on egg weight loss in farm “A” were also examined. The research objective was to impart a comprehensive knowledge on egg quality parameters of the main ostrich populations in Hungary and to compare the trios and the farms with each other and the international literature. We could reveal significant differences between trios in all egg quality traits. In conclusion, the shorter and the narrower the eggs were, the more spherical shape they had. Narrower eggs showed smaller surface area, volume, circumference and shell volume and vice versa. Eggs from farm “B” indicated significantly greater width, shape index, surface area, circumference and shell volume than farm “A”. A significant difference was observed in weight loss during storage between the farms. Weight loss in farm “A” was a multiple of farm “B”. In farm “B” there was a weak, positive correlation between storage period and weight loss (r=0.22, P≤0.05), in farm “A” it was not significant (P=0.52). There was no relationship between the initial egg weight and weight loss either in farm “A” or farm “B” (P=0,21, P=0,69). A slight positive correlation could be noted between egg porosity and weight loss (r=0.24, P≤0.05). Pores count presented here was less than the international results. Poultry eggs contain the most pores at the blunt end, less via the equator and the least at the pointed end. In ostrich egg we found more pores via the equator against the blunt end. To draw more precise conclusions, further investigation should be carried out on porosity. Considering the fact that the length of storage period and the weight loss during incubation are in strict correlation with hatchability, we intend to extend our research aims to these traits.

Lambing Frequency in the Ile de France, Suffolk and Babolna TETRA Stocks of Babolna c.o., Szendrő
29-32Views:675Lambing frequency of three different genotypes was evaluated in the breeding stock of Babolna c.o. Szendrő. Ile de France, Suffolk and Babolna TETRA breeding ewes gave the data for the further evaluation. The main aim of this research was to find out if there is any significant effect of selected parameters (registration class, lambing season, lambing type and the years) on the lambing frequency, the period between consecutive lambings. Production parameters of 9,471 Ile de France, 1,244 Suffolk and 7,618 Babolna TETRA ewes were collected and processed. The analysis covered the period between the years 1989-1999. It was concluded that not all of the evaluated parameters had a significant effect on lambing frequency. Not all of the genotypes showed significant differences, according to the examined parameters.

Genetic diversity study in Hungarian coldblooded horses
29-34Views:761Because of the feeding technology innovation, accelerated transport and communication facilities breeds of high performance breeds replaced local autochone breeds worldwide. These latter species however have an important role in gene conservation. Hungarian cold-blooded horse breeding stock are lacking pedigree, the actual founder breed mares are not known. For this reason, it is an major priority defining the genetic backround of the existing flock, for that breeding could operate with purposeful using of origin maternal founders. In the present study 195 cold-blooded Hungarian mares tail and mane sample were analized. Our analysis was carried out between 15531–15752 base pairs in mithocrondial DNA D-loop region, which reported a total of 222 base pairs. Fourtyone polymorphic sites were determined, which resulted in 39 haplotypes (h=39). The average pairwise differences were k=6.825. High haplotype and nucleotide diversity values were observed (Hd=0.968±0.003, π=0.026±0.003). Based on the previously defined variable positions of haplotypes defined by Jansen et al (2002), we groupped our haplotypes into haplogroups. 23 percent of the studied population (45 mares) belonged to haplogroup F1. Nearly 97% of the analyzed population was classified into one of eight haplogroups defined by Jansen.et al. (2002). This study gives genetic information nearly 25% of the Hungarian population. Another possibility would be patterning more mares or involving more genetic marker in the study which will assuming the possibility of a more comprehensive analysis.
