Degradability characteristics of oats hay (harvested at milk stage), oats straw, wheat middlings and forage legumes (lablab (Lablab purpureus)) hay, leaves of sesbania (Sesbania sesban) and tagasaste (Chamaecytisus palmensis)) were evaluated in three sheep given native hay supplemented with cott...

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...

Sixteen rumen fistulated Ethiopian Menz type sheep were used in a completely randomized block design in experiment 1. Unchopped teff straw was fed alone or supplemented with either 100, 150 or 200 g/d of sun-dried vernonia leaves. The chemical composition of fresh, boiled, water-soaked and sun-dr...

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...

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...

Forty-four crossbred steers were used in a 252-day trial to assess the feeding value of forages from two cereal-legume cropping systems Cropping system 1 comprised oat-vetch (Avena sativa-Vicia dasycarpa), wheat-trifolium (Triticum aestivum-Trifolium steudneri), teff (Eragrostis tef) and cowpea )...

This study characterized the degradability of cowpea (Vigna unguiculata) and Dolichos lablab (Lablab purpureus) hays (trial 1) and the effect of these legumes on rumen ammonia concentration (RAC), particulate passage rate (K1) and intake (trial 2) and the degradability of teff (Eragrostis tef) st...

This study investigated the effect of feeding oats hay alone or with 250 g of dolichos lablab (Lablab purpureus, 50 percent flowering at harvest) hay, wheat middlings, leaves of sesbania (Sesbania sesban) or tagasaste (Chamaecytisus palmensis) on the growth of 66 Ethiopian Menz sheep and the nutr...

22 yankasa lambs were slaughtered, jointed and dissected after a 184-day feeding experiment involving 4 planes of nutrition: High-high, (HH) high-low (HL), Low-high (LH) and Low-low (LL). Part of the results of the feeding experiment have been reported by lakpini et al. (1982). The carcass weight...
