Data on 1619 litters from 7 herds were analysed. For Landrace, Large White and Duroc pigs resp., piglet birth weight averaged 1.51, 1.39 and 1.47 kg and 21-day weight 5.50, 5.40 and 5.14 kg, and litter weight averaged 15.39, 15.14 and 14.05 kg at birth and 50.16, 51.41 and 42.40 kg at 21 days, the differences between Durocs and the other 2 breeds being significant.
