Foods produced from two cereal-legume cropping systems were evaluated in a 250-day growth trial using Friesian X Boran crossbred steers. Crops and crop combinations in cropping system 1 were oat-vetch (Avena sativa-Vicia dasycarpa; OV), wheat-trifolium (Triticum aestivum-Trifolium steudneri; WT),...

The paper evaluates the effects of forage type and level of concentrate supplementation on forage intake, diet apparent digestibility, purine excretion and milk production. Twelve crossbred cows (Bos taurus X Bos indicus), in early lactation were allocated to the following six dietary treatments:...

Twenty five rumen fistulated Ethiopian Menz sheep were used in a completely randomized block design to determine roughage utilization when different types of supplements (sesbania, leucaena, cotton seed cake (CSC) and forms (fresh or dry leucaena) were fed. The chemical composition, intake, diges...

The potential forage value and appropriate length of study on intake and relative palatability ranking of 40 multipurpose tree species (MPTs) were determined using 24 sheep blocked on live weight and age. As the MPTs had different dry matter contents, intakes were also expressed as a ratio of qua...

A series of trials were conducted to study the effect of either nitrogen source or supply pattern on the growth, rumen fermentation pattern and utilisation of straw by Ethiopian Menz sheeAll experimental sheep were given teff straw basal diet (CON). Irrespective of the trial, treatment sheep were...

The study aimed at examining the effects of replacing urea with protein nitrogen (N), source of protein and the quantity of rumen degradable N (RDN) in the diets of steers on rumen fermentation, outflow rate and intake. In experiment one, six ruminally cannulated Friesian steers were used in a re...
