Abstract

Preweaning growth traits and neonatal weakness (NW) were studied in Red (RB, n=82) and Grey Brahman (GB, n=37) calves. At birth, males calves were heavier than females (31.6±0.9 vs. 28.5±0.8 kg; P<0.002), calves experiencing NW were lighter (29.0±1.1 vs. 31.2±0.6 kg; P<0.06) than normals, and ...

Abstract

Weaning performance of 1393 purebred calves for heritability, genetic, phenotypic, and environmental correlation, as well as factors influencing weaning performance (year of birth, season of birth, sex, and number of calving) were evaluated. Traits included were weaning weight (WW), preweaning...

Abstract

Body weight at weaning of 1002 Ayrshire × Boran crossbred calves averaged 138 kg. The weaning weight of calves born in Aug.-Oct. and Nov.-Feb. was 20.2 and 1.0 kg respectively higher than average, and that of calves born in Mar.-May and June-July was 19.9 and 2.5 kg below the average weight. The...

Abstract

For 1736 Nellore calves in Brazil, body weight at birth and weaning averaged 29.10±0.31 and 154.0±2.4 kg resp. Herd, sire within herd, sex of calf, the contemporary group effect (based on season and year of calving, and management) and age of dam all had a highly significant effect on birth weight, ...

Abstract

For 974 ♂ and 883 ♀ Tabapuã calves from 46 sires and 937 dams, birth weight averaged 31.35±0.35 kg; it was significantly affected by sire and sex of calf, which accounted for 7.07 and 4.73% resp. of the variation in birth weight. Body weight at 90 days averaged 92.80±0.88 kg, and was significantly...
