Opis:
Seven genes (BF, EGF, ESR, FSHB, H2AFZ, LEP and PRLP) were studied as candidate gene influencing eleven reproduction traits (interval between litters (IBL), percent of litter (PL), number of litters (NL), number of piglets born dead (NBD), number of piglet born alive (NBA), total number born (TNB), mean of born alive (MBA), mean of born dead (MBD), mean of born total (MBT), mean of piglets at 21 days of age (M21D) and growth rate (GR) in three pig breeds (Hungarian Large White (HLW), Duroc and Pietrain) by PCR-RFLP. Based on the observed vs. expected genotypes frequencies populations across loci were in Hardy-Weinberg equilibrium (P>0.05). In case HLW breed ESR and FSHβ genes were in disequilibrium. Association study suggested that only EGF gene showed significant influence on the trait NBA and TNB. The AA genotype are preferable for sows, associated with higher NBA and TNB. The longest IBL, and the highest NL is associated with AB and AA genotype of EGF gene. IBL is significantly shorter in case of pigs with AB and AA alleles than BB alleles of PRLP genes. Selection for these SNPs could improve the reproductivity in the studied breeds.

Opis:
Genetic polymorphism at the β-lactoglobulin (β-LG) loci in indigenous sheep breeds (Tsigai, Racka, Pramenka) was determined. Altogether 904 sheep were genotyped for the presence of the A, B and C alleles of β-lactoglobulin by PCR-RFLP. The AB genotype was the most common and the β-lactoglobulin A was the most frequent in the Cokanski Tsigai (54%), while the B allele was the most common in the Rusty and the Zomborski Tsigai (59%, 60%). The C allele was found only in one individual from Serbian Cokanski flock. These results differ from those that refer to other native sheep breeds. In the Cokanski Tsigai, deviation from the Hardy-Weinberg equilibrium was detected. Genetic relationship based on β-lactoglobulin polymorphism was the closest between the Rusty and the Cokanski Tsigai among the studied populations and between sheep and goat among the other ruminants. Part of the promoter region (254 bp) of β-LG in studied sheep breeds were sequenced in order to identify polymorphisms, analyze haplotypes, and phylogenetic relationship among them. Sequencing analysis and alignment of the obtained sequences showed one haplotype. Analysis of more samples and longer parts of the promoter region of β-LG are needed to reconstruct a phylogenetic tree.

Opis:
The main objective of the current study was to obtain preliminary results on genetic polymorhism of A and C variants at the CSN2 locus in indigenous Romanian goat (Banat White, Carpatina) breeds using a rapid and efficient genotyping method, TaqMan assay (Applied Biosystems, USA). Hair follicle samples were taken from 73 Banat White and 82 Carpatina purebred goats from Arad, Caras-Severin and Timis counties. After the optimization of the genotyping assay it was found that the most frequent allele at the CSN2 locus was C in Banat White breed, while CSN2*A and CSN2*C showed similar frequencies in Carpatina breed (0.51 and 0.49, respectively). All three genotypes were detected in the two studied breeds, however, AA was the least frequent, especially in Banat White. The studied polymorphisms are potential markers for milk production in the studied breeds and the results will be useful in future works aimed at identifying possible associations with milk production traits, in order to test the feasibility of producing hypoallergenic organic goat milk.
