Effects of Introducing Different Levels of Groundnut Hay Treated with Urea and Molasses on Performance of Desert Lambs (Hammari Ecotype)

Abstract

Non-traditional agricultural by-products are a potentially valuable alternative source of animal feed which may decrease dependence on traditional feed products and decrease overall feeding costs. This experiment was conducted to evaluate the effect of using groundnut hay in lambs fattening. Groundnut hay was used at three levels (0, 20 and 30%) in three iso-energetic and iso-nitrogenous diets (A, B and C). Twenty seven male lambs of Sudanese Desert sheep (Hamari ecotype) were selected according to their age (4-5months) and average live body weight (20.5Kg) and they were kept in Rural Development and Extension Center (R.D.E.C). The experimental feed includes three different levels of groundnut hay treated with urea and molasses (0, 20 and 30 %). Experimental animals were fed for 60 days included two weeks as adaptation periods. All the data was collected and statistically analyzed by using statistical package for Social Studies (SPSS version 17.0). an A Completely Randomized Design (CRD). One way analysis of variance (ANOVA) and Duncans multiple range were used to test for difference among the treatments means. The study showed a significant differences (P>0.05) among different treatments for average values of final live body weight gain(FLBWG), total live body weight gain(TLBWG), daily live body weight gain(DLBWG), feed conversion rate(FCR), feed conversion rate as % of live body weight gain, cost of one kg feed and cost of one kg live weight per (SG). While initial live body weight (ILBW) and daily feed intake (DFI) showed no significant differences (P>0.05) among different treatments. Treatment A (control) reported the highest and best values of final live body weight, daily weight gain, cost of one kg feed, and cost of one kg live weight followed by treatment B (%20) while treatment C (30%) reported the lowest values so, we recommend to use groundnut hay up to 20% for finishing desert lamb.
