Abstract:

The study was conducted at Haramaya University goat farm using 24 intact Hararghe Highland sheep with a mean initial body weight of 16.02±2.5 (mean±SD) to investigate the effect of feeding dried Atella with concentrate mixture on feed intake, apparent digestibility, body weight change, feed conversion efficiency, carcass and meat quality evaluations as well as the economic feasibility of feeding regime of sheep fed a basal diet of grass hay. The experiment consisted of 90 days of feeding trial and 7 days of digestibility trial followed by the evaluation of carcass parameters at the end of the digestion trial. The concentrate mixture was prepared from 2:1:1 ratio of wheat bran, noug seedcake and maize, respectively. Atella was collected from local Tella makers and sun-dried on plastic sheet. The treatments were 100% concentrate mixture (T1), 67% concentrate mixture + 33% dried Atella (T2), 33% concentrate mix + 67% Atella (T3) and 100% Atella (T4) and animals in all treatments were given hay ad libtum. The supplement amount was offered on an equal amount (350 g/day) as in fed basis. The experiment was conducted using RCBD. Based on the initial body weight, the experimental sheep were blocked into six blocks of four animals each and randomly assigned to one of the four treatments within the block. The CP content of the supplement was 20.85, 21.17, 21.49 and 21.8 for T1, T2, T3 and T4, respectively. Dietary supplement types had no significant effect (P>0.05) on total DM intake as well as nutrient intake, except CP. Sheep in T4 had high (P0.05) across treatment groups, except CP digestibility, which was lowest (P
