Morphometric characteristics and consumer acceptability of meat from Potchefstroom Koekoek, Black Australorp, Venda and Ovambo chickens.
Indigenous chicken production receives little institutional support and resources because of lack of information on the socioeconomic importance, morphometric characteristic and meat quality of indigenous chickens. A cross ...
Diet selection and foraging efficiency of Nguni goats in the bushveld of Gauteng, South Africa.
Diet selection and foraging efficiency are primary driving behavioural processes in mammalian herbivore plant interaction. They determine the quality of production and also impact on vegetation, necessitating managerial ...
Effects of within-litter birth weight variation of piglets on performance at three weeks of age and at weaning.
The impact of within-litter weight variation on the productivity of pig enterprises is poorly understood. The objective of the study was to determine the effect of within-litter birth weight variation on litter performance ...
The effect of crude protein and calcium intake on fertility of male broiler breeders.
Broiler parent stock are selected to ensure that good characteristics will be passed to the offspring but management of broiler breeder birds is different to that of broiler chickens. Feeding broiler breeders ad libitum ...
Degradation parameters and modelling of degradation rate in the rumen of cattle fed non-supplemented roughages.
Feeding of animal has become increasingly a big challenge in livestock production systems as it is the most costly input. Ruminants are very important to mankind because they can convert fibre-rich vegetation into high ...
Influence of water salinity on growth performance and physiological responses in Nguni goats.
A survey was conducted to investigate factors influencing water scarcity for goats in areas where there are seasonal and perennial river systems in poor resource-limited smallholder communal farming systems. About 8 and ...

The effect of crude protein intake on fertility in young and old male broiler breeders.
Due to genetic selection and improvements in broiler growth traits there have been negative influences on fertility in broiler breeder parents. This is mainly related to excess body weight gain resulting in the inability ...
