Low feed quality, short periods of grazing each day and the need to search for forage are all constraints on cattle productivity in most parts of Africa. From the literature reviewed, it was observed that many factors affect the intake and utilization of feeds and that no single factor controls i...
Studies the possibility of using faecal Na concentrations as an indicator of Na status in cattle. Two roughage-based diets composed of equal parts of roughage and concentrate were fed to Friesian X Zebu calves. The roughages were either oat-vetch hay or barley straw. Animals were grouped accordin...
Supplementation of basal diets with multipurpose trees (MPTs) increases essential nutrients available to rumen microbes, increases rate of passage of particulate matter by 23-53 percent and of liquid matter by 9-43 percent. Supplementing teff straw with graded levels of cowpea or lablab significa...
A greenhouse trial was carried out at the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT), at Sadore (13°15' N, 2°18'E), Niger. Experiments were conducted in conjunction with a feeding trial. The feeding trial yielded eight types of compost made from faeces and leftove...
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 ...
Livestock under holdings of low-resource producers in the tropics are faced with a variety of feeds that are qualitatively and quantitatively deficient in available nutrients. Emerging practices of hay-making and inter-cropping of cereal with legumes have improved feed quality, but the lack of ap...
Where VRI is a function of basal roughage quality (nitrogen and fibre (NDF) contents, rumen dry matter degradability), CF basal is the correction factor for other attributes of the roughage (cropping and processing methods and forms of offer), CF sup is the correction factor for supplement attrib...
The results of the research showed that hay intake was 10 percent greater in working compared to non working cows. Cows responded to underfeeding by a progressive adaptation until a new equilibrium between dietary supply and requirements was reached. However, in draught cows fed low quality rough...
