Abstract excerpt

A selection project produced control cows from continuous matings with breed average bulls for predicted transmitting ability for milk (PTA-milk) in 1964 and select cows from matings to four of the highest PTA-milk bulls each year since 1964. Blood samples were collected in 1992 when milk yield d...
