Abstract:

The study was conducted at Ambo University using twenty five Horro sheep with initial body weight of 16.84±0.23kg (mean±SD). The objectives of the experiment was to evaluate effect of replacing concentrate mix with Lablab purpureus hay on feed intake, digestibility, live weight gain, and carcass characteristics of Horro sheep fed natural pasture hay as basal diet as well as to assess the economy of replacing concentrate mix with Lablab purpureus(LP)hay. At the end of feeding trial, digestibility trial and carcass parameters evaluation were carried out. The experimental sheep were blocked into five blocks of five animals based on their initial body weight and randomly assigned to one of the five treatment diets within a block. The treatments were natural pasture hay fed ad libitum to all treatments plus 100% CM/day (T1, CM supplemented), 75%CM:25%LP/day(T2), 50%CM:50%LP/day (T3), 25%CM:75%LP/day (T4), 100%LP/day (T5). The experiment consisted of 7 days digestibility and 90 days feeding trials after quarantine and adaptation period to the environment and experimental feed. Feed offered and refused and feces voided were recorded throughout the respective study period; while body weight change was recorded at 7 days interval. The CP contents of NSC, LP, WB, MG and NGH were 31.1, 21, 18.7, 8.2 and 7.4%, respectively. Organic matter ranged from 87.8% (NGH) to 98.1% (MG). The mean intake of basal DM in T5 (523.4±3.13 g/d) was greater (p
