This study was aimed at determining the effects of feeding an energy source on nitrogen utilization by Ethiopian Menz rams. Intake, digestibility, teff straw degradation, rumen pH and ammonia-nitrogen, nitrogen balance and purine derivatives were measured in the digestibility and nylon bag studie...

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...

Six rumen cannulated sheep (26.1 (s.d. 2.24 kg live weight) given maize stover ad libitum were supplemented with either sunflower cake (SFC), decorticated cottonseed (CSC) or noug cakes (NGC) with or without crushed maize grain. The 6x6 Latin-square experiment studied the degradation properties o...

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...

This manual has been produced to standardise some analytical procedures at ILCA and among those NARS scientists who may be interested in the aspects of feed evaluation that the manual attempts to address. The first part of the manual is on determination of voluntary intake, digestion and retentio...
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 ...
