Mineral mixtures constitute an important component of animal feed. There is no any specific mineral mixture supplementation is available for lambs in India. The present study was conducted to evaluate the effect of mineral supplementation on growth, nutrient intake, feed efficiency and feed conversion ratio of growing lambs. The feeding trial was conducted for a period of 120 days on 18 male lambs (Body Weight 17.07 Kg and four-month-old) of Munjal breed which were randomly divided into two dietary treatment groups and a control group with six replicates per treatment. The treatment group-T1 was fed with the conventional mineral mixture and the treatment group-T2 was fed with BIS specified mineral mixture (Type-I) supplementations @ 2%, whereas, the control group (C) was fed without any supplementation. The proximate nutrient compositions of concentrate mixtures in all the three groups were identical in respect to CP, EE, CF and NFE. During digestion trials of 120 days for C, T1 and T2 groups, the mean body weight gains (kg) were observed as 08.79, 10.08, 10.32; the nutrient intakes of TDN and DCP (gm/day) were observed as 602.21, 628.96, 637.15 and 59.08, 61.38, 64.63, respectively. The feed efficiency (gain to feed ratio) were observed as 0.111, 0.126, 0.131, whereas, the feed conversion ratio was observed as 8.98, 7.94, and 7.66, respectively for C, T1 and T2 groups. Based on the results, it was concluded that BIS specific mineral mixture supplementation was found to have significant (P<0.05) and positive effect on the body weight gain, nutrient intake, feed efficiency and feed conversion ratio as compared to the control group, whereas, these parameters showed non-significant but apparently positive effect as compare to conventional mineral mixture. It was inferred that the supplementation of BIS specific mineral mixture in conventional diet of lambs was helpful in improvement of the daily body weight gain, feed efficiency and feed conversion ratio.
