Abstract

An experiment was conducted to evaluate fattening performance of 24 Menz ram lambs fed grass hay basal diet and supplemented different concentrate mixes. The treatments were T1 (30g wheat bran 133g broken lentil screening), T2 (235g broken lentil screening only), T3 (285g wheat bran only), and T4 (227g wheat bran and 120 broken lentil screening). Concentrate mixes affected (P ≤ 0.01) the daily total dry matter intake (TDMI), concentrate dry matter intake and total crude protein intake of the lambs with the highest TDMI (814.47g) recorded at T4. Final body weight attained, total body weight gain and average daily body weight gain of lambs on T4 were highest (P ≤ 0.001). The experimental lambs showed lower (P ≤ 0.01) feed conversion efficiency (0.06) in T1 than the values recorded from T2, T3 and T4 diets. Sheep assigned to T4 and T3 diets showed higher (P ≤ 0.05) dry matter digestibility than in T1. Total nitrogen intake nitrogen digestibility and nitrogen retention were higher (P ≤ 0.001) for lambs in T4 than T2, followed by T3 and T1 diet categories. Thus, a 227g wheat bran and 120g broken lentil screening concentrate mixture supplementation on grass hay basal diet was the best for fattening of Menz ram lambs.
