Studies have been made of the digestion of nitrogen (N) and of organic matter (OM) in sheep offered thirteen gramineous roughages of widely differing nutritive value. It was concluded that the true digestibility of crude protein in the intestines ranged from 74 to 82% (mean 78%). These estimates were based on observations that, while metabolic faecal N (MFN) was equal to 0.4 g/100 g OM intake, ...

on experiment was designed for evaluating the nutritienal characteristics and physico-chemical properties of steam treated sugarcane pith (19 bar, 3 min.) and some other roughages. steam treatment resulted in a significant decreased (p<0.05) in ndf (77 vs. 55%), hemicellulose to cellulose ratio (0.54 vs. 0.10) and increased hemicellulose solubility of and soluble sugar fraction (20 vs. 124 mg/g...
