Abstract
To investigate β-lactoglobulin polymorphism using polymerase chain reaction – restriction fragment length polymorphism in Polish Mountain, East Friesian, Polish Merino and Austrian Bergschaf sheep raised for milk production, three β-LGB genotypes (AA, AB and BB) were found in all the groups, AB being the most frequent genotype in all the groups. The frequency of β-LGB A genes was 0.66 in Friesian, 0.55 in Bergschaf, 0.5 in Polish Mountain and 0.48 in Polish Merino sheep with no deviations from genetic equilibrium according to Hardy-Weinberg law. The relationship between β-lactoglobulin genotype and milk yield and milk composition was investigated, but no statistical differences were found. The present findings provide no conclusive evidence about the effect of different β-LGB variants on milk production traits in sheep.
