Abstract

This research aimed to know the performance of local rams fed diets containing treated corncob waste and rice husk ash filtrate 20%. Completely randomized design was used as an experimental method in this research. Collected data ewre analyzed using analysis of variance followed by Duncan multiple range test. Twenty local rams allocated in to four diet treatments, they were R0 = 60% fresh grass + 40% concentrate, R1= 30% grinded corncob + 30% fresh grass + 40% concentrate, R2= 60% grinded corncob + 40% concentrate, R3 = 30% treated grinded corncob + 30% fresh grass + 40% concentrate, R4 = 60% treated grinded corncob + 40% concentrate. Corncob was hydolized by rice husk ash filtrate 20% during 3 hours. Treated diets have a significant effect (P<0.05) on feed intake, average daily growth and chest hoop but no significant (P>0.05) on shoulder height, body height, waist hoop, feed conversion and feed cost per gain. Lambs fed diets containing 30% treated corncob showed the highest (P<0.05) daily growth gain (84.41 g/day) and chest hoop (11.19 cm). In conclusion, the utilization of treated corncob in 30% of the diet produced the best performance.
