Abstract:

The study was conducted to evaluate the effect of soybean or groundnut straw replacement for hay on feed intake, nutrient utilization, live weight change and carcass characteristics, of Gumuz sheep at Pawe Agricultural Research Centre. Thirty yearling male intact Gumuz sheep with initial body weight of 18.91 ± 2.6 kg (mean ± SD) were used in the experiment. The study consists of 90 days feeding trial and 7 days of digestibility trial after acclimatization of 15 and 3 days for the treatment feed and caring of faecal collection bag, respectively, followed by evaluation of carcass characteristics at the end. The experimental design used was randomized complete block design. The experimental animals were grouped in to six blocks of five animals in each block based on their initial BW and each animal within each block was randomly assigned to one of the five treatment diets; namely, Hay alone basal diet (control treatment; T1), 50% Hay + 50% soybean straw(T2), 50% Hay + 50% groundnut straw(T3), 25% Hay + 75% groundnut straw(T4), and 25% Hay + 75% soybean straw(T5). For all treatment groups 172g of toasted soybean grain and 5% of daily feed intake molasses was given with the same amount throughout the experimental period. Water and mineral lick were available free choice. Natural pasture hay, soybean straw and groundnut straw contained 7.12, 4.39, and 8.08% CP, respectively. The total DM intake of T1, T3 and T4 was higher (P
