The study involved 102 Holstein-Friesian cows imported from Sweden, kept on a farm in the West Pomerania Province. Beta-lactoglobulin (LGB) genotypes were determined using PCR (Polymerase Chain Reaction) method according to Medrano andAquilar-Cordova [1990]. It was found that cows with the LGB AA genotype had the highest milk yield in all analysed 305-day lactations. The differences were significant...
The aim of this study was to determine the association between polymorphism located in exon 8 of PPARGC1A gene (Cys430Ser) and carcass quality in pigs. Experiment was carried out on 350 PIC hybrid fatteners. Polymorphism was analyzed using PCR-RFLP method. The frequency of genotypes was as follows: AA – 0.33, AT – 0.57, TT – 0.1, however alleles: A – 0.62, T – 0.38. In the analyzed population loss...
