摘要

This study was conducted at Konso woreda (southern Ethiopia) to evaluate feed intake, digestibility, body weight gain and carcass parameters of Black Head Somali sheep. The experiment consisted of four treatments; and conducted in a randomized complete block design using twenty four sheep. The treatments were grass hay ad libitum fed alone (Control), hay+300g Tata (HT); hay+300g concentrate mix (HC); and hay+150g concentrate mix +150g Tata (HCT). Total DM and CP intakes as well as the apparent digestibility were all improved by supplementation with relatively better responses in HCT. The concurrent advantage of supplementing concentrate mix together with tata is clearly observed in the DM and OM digestibility of animals in HCT treatment which had higher values (P0.001) than the other two supplemented treatments (HT and HC) and control treatment as well. Supplemented animals had higher average daily gain and rib eye area (P0.001) as compared to control. Animals supplemented with tata (HT) showed similar performance to those supplemented with concentrate mix (HC treatment) in hot carcass weight, empty body weight and dressing percentages. The results of this study highlighted that tata has a feeding potential similar to concentrate mix, and can replace concentrate mix as a supplement to sheep fed a basal diet of hay grass.
