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...

Rumen fistulated Friesian X Zebu lactating cows were freely fed on diets containing oat-vetch hay ad libitum plus cottonseed oilmeal with 1.5 kg barley 1 or 3 kg with added sodium chloride 0 or 3 g/kg diet (low and adequate Na) in a 2 X 2 factorial design with periods of 20 days.

The macro mineral status of cattle in the Selale highlands of Ethiopia was evaluated during the rainy and dry seasons of 1989 and 1990 in terms of mineral concentrations in soils, feeds, blood plasma and faeces on 25 farms. Bone samples from animals of local breeds from a slaughter house were col...

The trace element status of crossbred Friesian X Zebu (Boran) and local Zebu cattle in the Selale highlands of Ethiopia was evaluated during the rainy and dry seasons of 1989 and 1990 interms of the trace element content of soils, feeds, blood plasma and faeces on 25 randomly selected farms. Live...

An experiment was carried out with four rumen fistulated crossbred Friesian X Zebu lactating cows to evaluate the Na content of faeces as an indicator of Na deficiency in cattle. In addition, the effect of NaCl supplementation on the animal performance and rumen parameters was examined. The cows ...

Two roughage-based diets composed of equal parts of roughage and concentrate were fed to 45 crossbred Friesian X Zebu (Boran) calves. The roughages were either oat-vetch hay or barley straw. 25 animals were fed the diet based on oat-vetch hay and 20 the barley straw-based diet. Within these group...
