Abstract
Eighty-one cows were formed into 21 sire groups to estimate variability attributable to sires for rate of milking, percentage of complementary milk, and milk production. Both rate of milking and percentage of complementary milk were related significantly to total lactational production. This experiment tends to show that faster milking cows have less complementary milk (more persistent) and consequently have higher lactation production.Keywords
