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),...

A static model for predicting either the growth rates or digestible organic matter (DOMI) required to meet predetermined levels of growth is developed. Parameters in the model were derived using data collected in ILRI-DZ laboratory from 6 growth studies (involving a total of 242 Ethiopian Menz sh...
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...
