Abstract

Eighteen Arsi-Bale (Local) and 18 Boer × Arsi-Bale (Crossbred) male goats, initially approximately 10 months of age, were used in a 12-wk experiment to investigate potential interactions between genotype and nutritional plane in growth performance, carcass and skin characteristics, and mass of non-carcass components. Grass hay (6.7% crude protein and 71.9% neutral detergent fiber) was consumed ad libitum supplemented with 150, 300, or 450 g/day (dry matter; Low, Moderate, and High, respectively) of a concentrate mixture (50% wheat bran, 49% noug seed cake, and 1% salt). Initial body weight was 20.7 and 14.0 kg for Crossbred and Local goats, respectively (SE = 0.36). Hay dry matter intake was greater (P
