Abstract

Effects of milk protein genotypes for αѕ₁-casein (αѕ₁-Cn), β-casein (β -Cn), k-casein (k-Cn), and β-lactoglobulin (β-lg) on first lactation milk yield, fat yield and fat percentage in milk samples from 195 Croatian Simmental cows were investigated. The effects of k-casein on fat yield and β - lactoglobulin on milk yield and fat percentage were significant higher fat yield was associated with k-casein BC. Fat.percentage was highest in milk from cows of β-lactoglobulin Bb. The AB genotype of β -lactoglobulin gave higher milk yield in the first lactation than AA and BB genotypes.
