Sažetak:
Milk samples from 248 Pag ewes, belonging to 14 different flocks and located through the Pag Island (Croatia), were analyzed by isoelectrofocusing and PCR-RFLP. Two genetic variants (A and B) and three genetypes (AA, AB and BB) of beta-lactoglobulin have been identified. According to the allele frequency (A=0.48, B=0.52) and occurrence of geneticvariants, the Pag breed is similar to other Mediterranean dairy sheep breeds. The observed genotype frequencies at the β -lactoglobulin locus (AA=0.185, AB=0.589 and BB=0.226) were significantly different from those expected from Hardy-Weinberg equilibrium. In comparison with 12 different studies related to Mediterranean dairy sheep populations, the significant departure from Hardy-Weinberg was also obtained in Valle del Belice sheep. However, the sample size required for detection of the same amount of departure from the Hardy-Weinberg as it was observed in Pag sheep was only sufficient in four studies (including Pag sheep). The superiority of the AB β -lactoglobulin genotype for milk production could be one of possible reasons for the observed excess of heterozygotes and ellele frequencies at intermediate level.
