For 1112 Polwarth and 380 Corriedale lambs born in Brazil in 1979-87, birth weight averaged 3.54 and 3.79 kg respectively for males and 3.35 and 3.49 kg for females, the differences between the breeds and sexes being significant. Birth weight was significantly affected by year of birth and age of...

Abstract

Data on 221 calves from 164 Charolais × Friesian (group 1) and (Simmental × Friesian) × Charolais cows (group 2), mated with Simmental or Hereford bulls, were analysed. Average daily gain from birth to the end of the grazing period (at 187.1 days of age) was 2.4% higher for calves from cows in...

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

Transfer of an embryo to each of 134 heifers 7 days after insemination resulted in 91 single and 43 twin pregnancies. For ♀♀ giving birth to single-born and twin calves, the incidence of stillborn calves was 4.5 and 7.6% resp., and 94.1 and 93.2% of calves born were weaned. Birth weight averaged 45 ...

Abstract

Approximate and exact Bayesian analyses of survival from birth to weaning, measured as an all-or-none trait were conducted for data on 2554 Rambouillet lambs using an asymptotic normal approximation and Monte Carlo numerical integration with importance sampling respectively. A linear logistic model ...

Abstract

For 6601 Pelibuey lambs, birth weight averaged 2.68±0.04 kg and weaning weight 14.4±0.12 kg; for 4727 lambs, preweaning daily gain averaged 103±1.17 g. Weaning weight and daily gain were significantly affected by flock, month of birth, sex of lamb and type of birth (single or twin), and year of...

Abstract

The growth curve from birth to weaning was estimated using data on 35 Retinta calves sired by selected bulls and 1142 calves in 10 commercial herds. The growth curve was significantly affected by herd, parity of dam, season of calving and sex of calf, but not by type of birth (single or twin) or...
