Sažetak
Among whey proteins beta-lactoglobulin is of particular importance. The gene (LGB) responsible for synthesis of beta-lactoglobulin in Bos taurus is located on the e1eventh chromosome genome. LGB is in two common variants, A and B polymorphic allelic variants, and several rare variants. The aim of this study was to determine the impact of LGB genotypes on milk production characteristics of the Croatian population Holstein breed. For the 112 cow in third lactation underwent genotyping for the LGB using RFLP-PCR method. Data on the qualitative and quantitative characteristics of milk are obtained from the HPA. There was a positive effect of AA genotype on milk yie1d and BB genotypes on fat content, while effect of genotype was not a significant on protein content. The results presented in this paper can be used in programs of selection and crossing of cattle in order to achieve efficient production of milk in terms of quantity and the usefu1 substances in milk.
