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 ...

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 examined the effect of lablab hay supplementation of crossbred cows fed forages from cereal+forage legume intercropping (maize–lablab (ML) stover or oats–vetch (OV) hay) basal diets on feed intake, apparent digestibility, milk yield and milk composition of crossbred cows. Forty eight m...

This study examined the influence of dietary variation on the usefulness of urinary spot purine derivatives (PD) collected at three periods (8:00-9:30, 14:00-15:30 and 20:00-21:30 hours) as predictors of intake by cattle. Diets comprised teff (Eragrostis tef) straw, fresh and dried Napier grass a...

Draft oxen have been used extensively by smallholders in many crop-livestock mixed production systems. In these system, crop production is totally dependent on oxen power. Other livestock have also been used for draft purposes depending on locality and circumstances. However, improved efficiency ...
