Abstract
Twenty ®ve growing crossbred bulls (Bos indicusBos taurus) were used in a randomised block
design experiment for 196 days to determine the effect of grainless concentrate containing different
supplemental nitrogen sources along with wheat straw based diet on feed intake, nutrient
digestibility, plane of nutrition and daily live weight gain. The animals in control group received
barley 30% in the concentrate mixture (Cm1) as a source of grain, where as other concentrate
mixtures contained only wheat bran (Cm2) or wheat bran supplemented with 2.5% urea (Cm3),
21.5% groundnut oil cake (Cm4) or 27% mustard oil cake (Cm5) as source of supplemental
nitrogen. Fortnightly live weight gain was recorded and a metabolism trial of 6 days duration was
conducted after 120 days of feeding trial in order to assess nutrient utilisation and retention as well
as plane of nutrition.
The mean dry matter (DM) intake and digestibility of the nutrients except crude protein (CP)
were similar in all the groups. CP digestibility was signi®cantly higher (P
