| Abstract: | Thirty-five male Afshari lambs (3.5 months old), with an average weight of 35 kg were randomly assigned to one of five experimental
treatments relating to optimal replacement level of rice bran in lamb finishing diets. The lambs were fed a milled concentrate
(3 mm screen) diet supplemented with 15% (DM basis) chopped (5 cm length) lucerne hay and chopped (5 cm length) maize silage
or wet (80% moisture) sugar beet pulp. Barley grain in the lambs’ diets was replaced by rice bran at either 0, 15, 30, 45
or 60% of the concentrate mixture on a dry matter basis. Results show that lambs fed 45 and 60% rice bran treatments weighed
significantly less than those fed with 15 and 30% and control group (P < 0.05). Average daily gain in lambs fed with concentrate
mixtures containing 45 and 60% rice bran were 33 and 47% lower than control, respectively (P < 0.05). Lambs that received
diets containing 45 and 60% rice bran, had lower feed intake (P < 0.05) than other groups. Using rice bran in the finishing
diet had no significant effect on dressing percentage, tail percentage, abdominal fat and visceral organ weights. These results
suggest that barley can be replaced with rice bran up to 30% in the finishing diets of lambs without any adverse effect on
lamb performance. |
