“…With comparable DM intake, weight gain as well as digestibility in all concentrate rations achieved with up to 50% substitution of concentrate in ration, less cost can be achieved with rapid growth rate of rabbits. Korake et al (2015) [6] reported in their experiment that feeding cost of live weight gain per kilogram in T 0 , T ).The results were in agreement with those of Radhakrishnan (2005a) [9] conducted experiment with weaned male kids fed with complete ration containing neem leaves at 0,20,40 and 60 percent level as roughage source and reported lower feeding cost per kilogram live weight gain in treatment group as compared to control. Radha Krishnan (2005) [9] showed the Madrared lamb fed with ration containing 60 percent of green fodder hay (T 1 ) and ration contained 60 percent of Neem: SS: GNH25:37.5:37.5, (T 3 ) Subabul: GNH:RS25:37.5:37.5 and (T 4 ) Gliricidia: GNH:RS 25:37.5:37.5 and recorded lower feeding cost per kilogram live weight gain in treatment groups as compare to control.…”
