Abstract excerpt

Two different methods were used to determine kappa-casein genotypes of Holstein sires. In the earlier procedure, genotypes of sires were deduced by analyzing frequency distribution data of kappa-casein variants obtained through typing of milk samples from daughters by electrophoresis. The second...
