Abstract
Growth rate, feed conversion efficiency, digestibility, nitrogen balance, water intake, blood picture and carcass traits of weaned growing Marwari kids fed three levels of (T1: 50 per cent, T2: 35 per cent and T3: 20 per cent), concentrate (Special Amuldan) in chaffed NB21 and lucerne hay based rations were studied from 22-1-89 to 11-6-89. A vitamin and mineral supplement was fed along with concentrate. The body weight and body weight gain of Marwari kids were affected significantly (P < 0.01) by treatments (T1: 18.78+0.88 kg and 82.500+3.72 g; T2: 20.35±0.06 kg and 82.178±6.22 g and T3 : 16.275±0.45kg and 48.670±5.77 g respectively) as well as by periods. Similarly, the biometry (heart girth, height at wither and body length) also significantly affected (P<0.01) by treatments (T1 : 58.62± 0.92 cm, 61.96+0.80 cm, 57.57+1.01 cm; T2: 58.97+1.13 cm, 61.72+1.31 cm, 60.31+1.30 cm, T3: 55.65+0.65 cm, 58.35+0.708 cm, 56.80+0.694 cm respectively) and periods (P < 0.01), However, with regards to body weight, body weight gain and biometry of kids maintained on 50 and 35 per cent concentrate level were at par but differed significantly from those maintained on 20 per cent concentrate level. The body weight was positively and highly significantly correlated with heart girth, height at wither and body length to the tune of 0.97±0.025, 0.87±0.051 and 0.91±0.04 respectively.
