Ruminal acidosis is discussed with reference to causes and economic and health implications. Distinction is made between the acute form which with proper adaptation to high energy diets is seldom encountered and the more problematic chronic or sub-acute form, commonly…
Young Afrikaner crossbred steers were used for the experiment after being fed ad lib until a desired estimated carcass mass of 120 and 240 kg was reached. Carcasses were split into sides - one group of sides served as controls…
The effects of restricting chickens and ducks to cages on their haematology (as compared to that of free-roaming animals) were investigated in this study. Significant differences were observed in several haematological parameters and the study showed that conclusions that could…
Copper (Cu) accumulated in the livers of sheep receiving high levels of dietary Cu but low levels of molybdenum (Mo) and sulphur (S). However. the liver Cu accumulation was much lower than levels found in similar trials in the literature…
The voluntary feed intake of non-pregnant, pregnant and lactating Merino- and S.A. Mutton Merino ewes on native pasture and chopped lucerne hay, was investigated. The crude protein content of the native pasture ranged from 8,6 per cent to 16,2 per…
The effect of replacing increasing amounts of cottonseed cake meal with urea in isonitrogenous (40 per cent CP) supplements for growing weaner steers has been investigated over a period of three years. Each year six groups of 30 Hereford x…
Twenty-four Friesland-cross calves were reared artificially in a 22-factorial experimental design for a period of 13 weeks. The two factors and levels investigated were (1) the fat content of the milk replacer, viz. 20,8 per cent (F1) or 12,6 per…
Citeria of condition are discussed and defined. Thirty-eight condition indices taken from nine adult male impala were tested for linear correlation with condition and total body fat. Indices derived from the complete dissection of a buttock proved to be the…
