[The effect of cow genotype for beta-casein on the quantitative level of milk proteins].
The quantitative content of 14 milk proteins was investigated in Bestuzhevskaya and Kholmogorskaya cows with different genotypes for beta-casein. It is shown that beta-CnA1 allele provides higher content of protein in corresponding variant, as compared to beta-CnB and beta-CnA2 (P less than 0.05-0.001). beta-casein quantity in milk is in following dependence on genotypes for beta-Cn: A1B less than A1A1 greater than A1A2, A2B greater than BB greater than A2A2. The effect of locus beta-Cn on the quantity of total protein, caseins and separate milk proteins was also found (eta 2 = = 0.098-0.147).
