Abstract

This study was aimed to determine the optimum dietary crude protein for fattening yearling Arsi-Bale sheep. Thirty-two intact male lambs (live weight=17.53±1.57 kg) were randomly assigned to five iso-caloric (2.12 Mcal/kg DM) dietary treatments (T), varying in crude protein: 9.4% CP (T1), 10.2% CP (T2), 11% CP (T3), 12% CP (T4) and 13.1% CP (T5). Intake and growth trial lasted for 87 days, followed by digestibility trial and carcass analysis. Treatments did not differ (P>0.05) in DM intake, ranging from 918.29 (T1) to 928.09 g DM/day (T3). Crude protein intake increased (P<0.001) with increase in dietary CP (T1, 86.71 g/day; 120g/day - T5). Intake of fiber fractions was highest (P<0.001) with 12% CP diet. Treatments varied in apparent digestibility of DM (P<0.05), CP (P<0.05), NDF (P<0.001) and ADF (P<0.001). Average final live weight, total gain and daily gain of lambs were increased non-significantly (P>0.05) from 22.71 to 23.96 kg; 5.37 to 6.35kg; 61.78-73.00 g/day, respectively. Feed conversion ratios were higher (P<0.001) in lambs fed 12%CP diet (12.61) and 13% CP diet (12.76). Urinary nitrogen and total nitrogen excretion were highest for 13% CP diet (5.02 and 9.19 g/day; P<0.001). Nitrogen balance was peaked (12.70 g/day, P<0.001) with 12% CP diet. There was no significant differences (P>0.05) among treatments in slaughter weight, hot carcass weight, DP, fat and bone proportions. However, hot carcass weight increased from 8.8 to 9.8kg and DP from 39.4 to 42.15, with feed CP increase to 12%. The results of this study indicated that optimum dietary CP for improved growth and feed utilization of yearling Arsi-Bale lambs, growing from 17 to 25 kg is 12% at the specified dietary energy. Suggested, detail study, applying "comparative slaughter technique" is warranted to support the present findings.
