Effects of some calving traits

Effects of some calving traits

KB Mitteilungen 27(1): 4-6

Data on 55 284 Swiss Black Pied, 227 686 Swiss Brown and 236 692 Simmental calves, sired by 139, 456 and 512 purebred and crossbred bulls resp. were analysed. For calves sires by bulls of the 3 breeds, birth weight averaged 43.5, 43.5 and 44.4 kg resp., gestation length 281.9, 288.5 and 286.6 days, the percentage of difficult calvings 2.6, 1.3 and 3.0 and that of stillbirths 2.8, 2.0 and 2.6.
