Varvikko, T.Vanhatalo, A.[The effect of differing types of cloth and of contamination by non-feed nitrogen on intestinal digestion estimates using porous synthetic-fibre bags in a cow]The effect of differing types of cloth and of contamination by non-feed nitrogen on intestinal digestion estimates using porous synthetic-fibre bags in a cow

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 to evaluate the effects of forage type and level of concentrate supplementation on forage intake, diet digestibility and milk production. Twenty-four crossbred cows (Bos taurus X Bos indicus), in early lactation, were allocated to the following six dietary treatments...

Metabolizable energy (ME) and crude protein (CP) of the stall-fed resources met half of the requirements of crossbred cows in the Central Ethiopian highlands. The average supply of ME and CP from stall-feeding supported a milk yield of 850 kg or 55 percent of the lactation yield. The additional M...

The effect of ensiling additives on ruminal and intestinal nylon bag degradation of grass silage cell wall constituents was studied. Herbage consisting of Dactylus glomerata and Phleum pratense was ensiled with the following commercial additives in small scale silos of 3m3. 1) AIV-2 containing 80...

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 ...
