An experiment was conducted to evaluate a hetero-yellow endosperm sorghum cultivar (G766W) in comparison to a low-tannin (GL) sorghum cultivar as well as maize in a growth trial using pigs. The digestible energy (DE) content of the experimental diets as…
Two trials were conducted to determine the effect of coagulation suppression of milk and milk replacers on apparent digestibility coefficients and body mass-gain of calves. In Experiment 1, two groups of five Holstein bull calves, two to four days of…
Fourteen Holstein calves, two to four days of age, were randomly divided into two groups to determine the effect of abomasal curd suppression on selected blood profiles. Calves received a milk replacer in which casein coagulation either was normal (CM),…
Production differences between Merino ewes from different regions and between their progeny as determined at a central testing centre. The first Merino championships for measured production took place in 1984. A total of 31 breeders each sent 12 ewes which…
Influence of copper and selenium supplementation in SA Mutton Merino ewes, kept on pastures with low copper and selenium concentrations, was investigated. Ewes which came into oestrus and conceived during March to April, were found to have concentrations of plasma…
The effect of lupin supplementation during mating on the reproduction of autumn-lambing Merino ewes was studied relative to an unsupplemented control group. A total of 158 ewes were available for lambing in 1985, 229 in 1987 and 185 in 1988…
True metabolizable energy, corrected for nitrogen retention (TMEN) and true lysine availability, was determined for maize and sunflower oilcake meal, two samples of each, and in samples of fishmeal, soyabean oilcake meal and sorghum meal using intact and caecectomized roosters…
