This article examines the changes in diet and health that occur when nomadic forest dwellers settle. Examples are drawn from African Pygmy groups such as the Kola, Medjan and Baka of Cameroon, the Aka of the Central African Republic and the Efe and Mbuti of the Democratic Republic of the Congo; a...
Two experiments were conducted to assess the nutrient intake, weight gain (ADG) and rumen degradation of napier grass (NG), lucerne (L) and sweet potato vines (SPV) fed to growing dairy heifers. In the first experiment, 33 Friesian heifers were randomly allocated to the three treatments namely; n...
A study conducted to characterize the effects of species-specific food habits, body size, and season on various aspects of diet quality and to evaluate diet quality with respect to established feeding standards for maintainance.
The relationship between in vivo and in vitro estimates of efficiency of microbial production (EMP) was tested using four silage-based diets. In vivo estimates were based on renal allantoin excretion in steers and in vitro estimates were based on a combination of gas volume and true substrate de...
Diet digestibility and the degradability and rate of passage of the roughage fraction were measured for four maize-based diets containing either 50 per cent (VH50), 33 per cent (VH33), 22 per cent (VH22) or 10 per cent (VH10) roughage as natural rangeland (veld) hay. Treatment diets were offered ...
Four maize-based diets containing either 50 per cent (VH50), 33 per cent (VH33), 22 per cent (VH22) or 10 per cent (VH10) rangeland (veld) hay were offered ad libitum to 40 castrated Matabele goats aged either 18 or 24 months and slaughtered after 10 kg liveweight gain. Ten additional goats of th...
Pigs self-fed diets in which whole cottonseed (including the hulls) replaced one third, two thirds or all the protein supplied by soybean meal gained at a reduced rate and mortality resulted at the highest levels. Iron from ferrous sulfate was ineffective in preventing toxicity because of physica...
