Abstract

Dry matter (DM) and neutral detergent fiber (NDF) digestibilities and rate and extent of disappearance of feed byproducts (cotton seed cake, wheat bran), legumes [berseem (Egyptian clover), lucerne (Medicago sativa), cowpea (Vigna sinensis)], grasses fmaize (Zea mays), millet (Panicum miliaceum), sorghum (Sorghum vulgare)] and wheat straw were determined in ruminally fistulated male cow calves. The in situ DMD and NDF digestibility (NDFD) of feed byproducts (FBP) and legumes were higher than grasses. Extent of DM digestion did not follow the same pattern as DMD and was lower in legumes than in grasses.

The rate of DM and NDF disappearance was higher (P<0.05) in FBP than in legumes and was lowest in grasses. Higher digestion rate of legumes than grasses was due to their higher cell solubles.
