Effect of supplementation with non-conventional agro-industrial by-products on rumen fermentation pattern and microbial nitrogen supply was studied in sheep fed grass hay for 9 days. Diets consisted of hay alone (control); hay supplemented with tela atella (traditional brewery residue); katikala ...

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 )...

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...

Yankasa sheep were used to study effects of palm kernel meal (PKM) on nutrient utilization and performance. The - in sacco - degradation studies revealed that potential protein degradation in the rumen was high but the very low rate of degradation (0.031 (per hour)) made 50-61 percent protein of...

The effect of tannins in browse supplements on intake, digestibility and live weight changes was evaluated using sixty-six male Ethiopian Menz sheep in a 90-day trial. Teff straw (Eragrostis tef) was fed ad libitum (control diet), or supplemented with 190 g dried leaves of six Sesbania sesban acc...

The aim of this work was to assess whether degradability, gas production or chemical constituents could predict the preference of browses. Forty tropical browse species leaves with a crude protein (CP) content ranging from 79 to 307 g kg-1 DM were used for this study. The neutral detergent fibre ...

The long term effect of supplementation of Leucaena pallida and Sesbania sesban on growth and reproduction performance was determined on 30 male Ethiopian highland sheep and 25 East African goats. Unchopped teff straw (Eragrostis tef) was given ad libitum and supplemented withe ither wheat bran (...
