Weaning mass was studied for 753 calves out of Africander cows by Africander, Brahman, Charolais, Hereford and Simmentaler sires. Crossbreds performed 11,1 per cent to 11,8 per cent better than Africander controls. Charolais progeny had a significantly greater weaning mass…
Urea-supplemented wheat straw (UWS) was substituted stepwise by urea-ammoniated wheat straw (AWS) in diets fed to SA Mutton Merino ewes during late pregnancy and lactation. The experimental animals were fed ad libitum under zero grazing conditions over the last 8…
The influence of sire breed and breed genotype of dam on birth and weaning mass in calves of Afrikaner, Hereford, Simmentaler and Bonsmara cattle, as well as F1 and two- and three-breed rotational crosses between Afrikaner, Hereford and Simmentaler were…
Simmentaler cattle of the Highveld Region Development Institute were used in this study to determine the genetic and envi¬ronmental effects on birth mass, weaning mass and the mass gain from birth to weaning. During winter the animals were kept in…
