Effect of glucosinolate of mustard- and rapeseed oil-cake on performance of crossbred cattle

Rumen fermentation of substrate was not affected by the level of glucosinol ates (extracted from mustard-cake) in vitro as indicated by the concentrati on of several metabolites, and gas production. In an another experiment, 18 crossbred males calves were distributed in 3 groups and groundnut-cake (GN C) in concentrate mixture of control group was replaced with mustard-cake(M C) and rapeseed-cake (RSC) on isonitrogenous basis. Growth performance, fee d conversion efficiency and nutrient utilization were studied during 35 wee ks of experimental feeding. Though the growth rate and feed efficiency were higher in GNC group than those in MC and RSC groups but variation among th e groups were not significant, The dry matter intake and digestibility coef ficients of proximate principles and cell wall constituents did not vary si gnificantly among the groups.
