Dairy traits of the progeny of Red-and-White bulls described through the genetic polymorphism of milk proteins and principally of fraction alpha S1-CN

Dairy traits of the progeny of Red-and-White bulls described through the genetic polymorphism of milk proteins and principally of fraction alpha S1-CN

Annals of Animal Science 2(1): 5-15

This study was conducted to characterize the dairy traits of the female progeny of bulls which left the most numerous groups of daughters in farms belonging to the Opole region, taking into consideration the polymorphism of milk proteins, principally of fraction alpha S1-CN. Milk production traits of 97 cows, which are daughters of 7 Red and White bulls were evaluated as well as the physicochemical properties of milk. 20 cows from 4 groups had genotype alpha S1-CN BC (frequency 0.129).
