This study determined nitrogen degradability and digestibility of rumen undegradable nitrogen using mobile nylon bag (MNB) and pepsin/pancreatin in vitro technique (IV) of 40 browse species. Thirty Ethiopian highland sheep fitted with rumen cannulae were used in nitrogen (N) degradability studies...

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 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 ...

Associations among chemical properties, in vitro digestibility and ruminal degradability characteristics of herbaceous legumes, browse species and oilseed cakes were studied using correlation analysis based on a total of 50 feedstuff samples. Chemical properties were poorly related to in vitro or...

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 (conducted in Debre Zeit, Ethiopia in 1993) examined (i) the effect of source of inoculum on in vitro dry matter (DM) digestibility (IVDMD) and gas production (GP) and (ii) the IVDMD, GP and in sacco degradability as predictors of in vivo DM digestibility (DMD( and intake. Six ruminall...

Five mathematical models were evaluated for their ability to describe ruminal degradability profiles of protein sources composed of herbaceous legumes, browse species and oilseed cakes. Degradability constants of dry matter, organic matter, nitrogen and neutral detergent fiber of the feeds were t...
