Effect of feeding different ratios of dried brewery grain and surplus cafeteria food on feed intake, body weight gain and carcass characteristics of Wogera sheep

Abstract

The demand for animal protein is increased due to the high global human population increase. Therefore, this study aims to evaluate the effects of feeding different ratios of dried brewers grain and surplus cafeteria food on feed intake, body weight gain, and carcass characteristics of Wogera sheep. Twenty-yearling Wogera ram lambs with an average body weight of 19.48 ± 1.64 kg were assigned to one of the five treatments using a randomized complete block design. The treatments were T1-100 % dried brewers grain (DBG), T2-70 % DBG + 30 % Student surplus Cafeteria Food (SCF), T3-50 % DBG + 50 % SCF, T4-30 % DBG + 70 % SCF, and T5- 100 % SCF. Grass hay was used as a basal diet. Grass hay and total dry matter intake were different (P ≤ 0.05) between treatments, with the highest record for T1. There were high records (P ≤ 0.05) of body weight change at T3 and low in T1. Blood, heart, kidney fat, liver with bile, intestinal free gut as well as nonedible components had differences (P ≤ 0.05) between treatments. In conclusion, supplementation of 50% DBG + 50% student SCF can improve the final body weight of fattening Wogera sheep.
