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 ...

Thirty Highland zebu oxen with a mean weight of 276 (SE ± 14.3) kg and about 6 years of age were blocked by weight into 5 groups of 6 oxen each and within groups allocated to 6 treatments. They worked for 51 days followed by 84 days recovery. Teff straw (Eragrostis tef) and lablab (Lablab purpure...

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 which the manual attempts to address. The first part of the manual is on determination of voluntary intake, digestion and retenti...

The effects of trypanosomiasis on digestible organic matter intake, milk yield and composition, dam liveweight changes during lactation and lamb growth rates were investigated at Ibadan, Nigeria 1991/92, using 20 West African Dwarf sheep nursing single lambs. Although digestibility coefficients w...

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...

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 (...
