Abstract
Twenty lambs with 21 ± 2.47 kg body weight were assigned in four groups each of five lambs used in growth performance experiment, while eight lambs of 28.5 ± 2.47 kg body weight were used in digestibility and blood parameters experiment of four equal groups each of two lambs. Lambs were fed four rations nominated as T1, T2, T3 and T4. Rations contained the same concentrate feed mixture (CFM) that was offered in amounts to meet 70% of lambs metabolisable energy requirements, while soy-bean straw (SBS) treated or untreated were available ad. libitum. Ration T1 contained untreated SBS, ration T2 contained 5% urea and 10% molasses treated SBS, ration T3 contained (T2 +8% beaker yeast) treated SBS and ration T4 contained (T3+ 8% fat) treated SBS. CFM contained 18.89% crude protein (CP), 6.35% ether extract (EE), 9.77% crude fiber (CF) and 54.62% nitrogen free extract (NFE). The untreated SBS contained 4.6% CP, 2.02% EE, 33% CF and 43.96% NFE. All treatments increased the CP content to 8.18%, EE to 7.58%, NFE to 45.08%, while the CF was reduced to 27.98%. Digestibility coefficients were significantly (P<0.01) improved. The highest TDN value was 65.86% (T4 ration), while the TDN value for T1 was 61.17%. The average daily dry matter (DM) intake of the growing lambs were 1.21,1.34, 1.36 and 1.38 kg, while the average daily intake of SBS were 0.353, 0.416, 0.420 and 0.450 kg for the four rations respectively. The average daily weight gains were 180, 208, 211 and 225 g for lambs fed rations T1, T2, T3 and T4 successively. Blood urea and ammonia values were significantly (p>0.01) higher in T2, T3 and T4 than in T1. Lambs fed T4 Showed significantly (p>0.01) higher concentration of Triiodothyronine (T3) 2.03 ng/ml than the other treatments. It could be concluded that the above mentioned biological positive effects may explain the increase in body weight gain and could suggest some good relative evidence for improving the nutritional value of the SBS treatments and supplementation.
