Investigation of the heat shock gene Hsp70 polymorphism in different sheep genotypes
Published December 16, 2012

Nowadays the climate change has an increasing effect on the animals. The warming climate brings up several problems on the area of the animal husbandry, which ones are really important. From the first time the living beings have defensive mechanisms against the heat shock. In current examination we use– from Hungary and from other countries c...ollected –samples of sheep breeds, which are living on different climate. Our fundamental assumption was, that the animals living on other climate adapted to the changes of the environment and there are differeces in their genetic background. These fixed mutations we are looking for in the HSP70 heat shock gene, but we haven’t found any polymorphism yet. We are going to involve further breeds and more individuals in the investigations.

Preliminary data on the effect of semi-synthetic baits for Noctuidae (Lepidoptera) on the non-target Lepidoptera species
Published June 2, 2015

Noctuidae are one of the most important Lepidoptera groups containing dangerous pest species. Monitoring and detection of these pest species is routinely performed by traps baited with sex-pheromones. Baits that attract both males and females were developed for improved pest management. First the effectiveness of different synthetic compounds evaluated. We also tested semi-synthetic baits that contained both synthetic and natural components (wine and beer). These were more attractive for moths considering species richness and abundance. Disadvantage of this increased effectiveness is that the traps catch more non target, rare and even protected species. In this study we analysed the effect of semi-synthetic baits developed for Noctuid moths containing wine on other non-target Lepidopterans. In the six sampling sites traps caught 17158 individuals of 183 Lepidoptera species. The number of Noctuidae species was 124, while their proportion was 84.4%. The traps caught 813 individuals of 9 protected and 20 valuable species, which was only 4.7% of all Lepidopterans. In contrast the mean proportion of 33 dangerous and potential pest species was 31.3% (5375 individuals). Number and abundance of both protected and pest species were affected by landscape structure. The risks of catching non-target species was higher in species rich natural and semi-natural landscape. In homogenous arable lands the number and proportion of valuable Lepidopterans was not significant.

The results of the investigation of the β-casein gene polymorphism in sheep breed – Review
Published August 29, 2017

β-casein is the most abundant protein fraction in sheep milk, and has at least six different alleles (A, B, C, G, X, Y). The alleles of the β-casein gene may influence on the quality and quantity of milk. Knowing the gene polymorphism has an important role in the process of milk production. The properties of milk could be positively influence...d by themolecular genetic methods.

Investigation of the β-casein (CSN2) gene polymorphism in goat breed – Review
Published August 29, 2017

Milk plays an important role in the human nutrition as an important protein and energy source. Β-casein is the most abundant casein fraction in the goat milk. The β-casein gene has at least 9 polymorphism in goat breed (A, A1, B, C, C1, D, E, 0 and 0’). The most important alleles are the zero (0) and zero’ (0’) alleles, because they dec...rease the quantity of β-casein protein in milk. The lower quantity of the β-casein changes the properties of the coagulation and the allergenin milk. This review is about the β-casein gene polymorphism in goat breed.
