Forty-five Friesian X Zebu crossbred calves (4 days old) were used to evaluate the effect of feeding different levels of whole milk and weaning at different ages. A total of 252 litre whole milk offered over 12 weeks was compared with a feeding level of 134 litre milk offered over 8 weeks. Water ...

An experiment was conducted with Friesian X Zebu (Boran) crossbred growing steers to compare an agro-industrial by-product, wheat middling cowpea hay, and wilted forages of leucaena and tagasaste as cattle feed. These feeds were fed daily to supplement the basal diet of native hay. A mineral supp...

Four ruminally and duodenally cannualated heifers were used to study the ruminal degradation of cell wall constituents of barley (B), barley fibre (BF) and wheat mill rum (WMR) using the nylon bag technique. The subsequent postruminal degradation of the feeds and their rumen - undegraded residues...

An experiment was conducted with four rumen-cannulated crossbred cows in a balanced 4x4 Latin square to study the effect of wilted tagasaste (Chamaecytisus palmensis) forage on rumen parameters and milk yield. The cows were fed a basal diet consisting of ad libitum native hay, mineral lick and wa...

An experiment was carried out to evaluate the effects of molasses, given at different times, on feed intake, digestibility, degradation of hay dry matter (DM) and rumen pool fermentation. Four ruminally fistulated Friesian X Boran crossbred non-lactating cows were given a basal diet of grass hay ...

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...

Four ruminal and duodenally cannulated heifers about 550 kg were used to study the intestinal N degradation of hay and grass silage. The animals were fed at maintenance hay or grass silage, without or with barley (0.70 X DM intake) in a 2 X 2 factorial design in 4 X 4 Latin square with periods of...
