Abstract

Twenty-five Barki lambs with an average body weight of 25 ±0.5Kg, at 8-months of age, were divided into 5-groups of 5-animals each, according to their live body weight in growth trial lasted for 90 days to study effect of replacing yellow corn by beet pulp in lambs diets with or without fibrolytic enzymes on carcass characteristics and meat quality. First group (G1) was fed the control ration, which consisted of concentrate feed mixture (CFM) and Alfalfa hay; second group (G2) was fed a ration where 50 % of the corn was replaced with sugar beet pulp (SBP); third group (G3) was fed a ration where 75 % of corn was replaced with SBP; fourth group (G4) was fed the same ration as G2 but supplemented with 4 g/head/day of fibrolytic enzymes and fifth group (G5) was fed the same ration as G3 but supplemented with 4 g/head/day of fibrolytic enzymes, like G4. Result showed that final slaughtered body weight (FSBW) was higher in G5 and G4 compared to other groups. However, the difference was significant (P<0.05) for G5 (45.2Kg) compared with the other groups. Significant main effects for enzyme supplementation, and SBP substitution at 50% and 75%, were noted on FSBW. Dressing percentage was similar for all groups, but the amount of protein in meat was higher in animals fed rations without enzymes compared to the control group. Eye muscle (longesmus dorsi) was significantly different for G5 compared with the control group. The colour of meat was the same for all groups, but protein content in meat was significantly higher for G5 compared to the other groups. It may be concluded that SBP may substitute yellow corn at 50 and 75 % in Barki lambs ration with enzyme positively effecting FSBW, as well as protein content in meat.
