A 4 month study was undertaken on 12 Marecha calves. Six (3 ♂ and 3 ♀) were housed at CBRS reared under semi-intensive management system (SIMS) while other 6 (3 ♂ and 3 ♀) were owned by private farmers (extensive management system EMS). In SIMS, the calves were fed gram residues (GR) adlib after the browsing daily for 8 hr. while in EMS, calves were allowed browsing and fed households. Water was provided twice a day. Fortnightly weighing at farm was done by digital scale while in field weight was assessed by formula using body measurements. Mean overall weight gain in 120 days and DWG was different (P<0.05) which found to be 47.67+2.59 kg and 0.397+0.02 kg/d; 44.33+2.59 kg and 0.369+0.02 kg/d of male and female in SIMS while 64.67+2.59 kg and 0.539+0.02 kg/d; 52.33+2.59 kg and 0.436+0.02 kg/d of male and female in EMS. Mean DFI (kg/d) of GR on DM basis was found to be 3.34+0.23 and 3.29+0.23 of male and female in SIMS while 3.50+0.23 for male and female in EMS. In blood bio-chemicals Hb, cholesterol, triglycerides, TP, sugar, Ca and P were P<0.05 while urea, creatinine and albumin were non-significant (P>0.05). Significant differences for Ca, Cu, Zn, Fe and Mn were found in wool.
