Responses of Corncob as Replacement of Elephant Grass on Performance and Carcass Profile of Bali Cattle

The purpose of this study was to determine the effect of corncob instead of elephant grass in the diet of cattle on the performance and carcass profile of the Bali Cattle. Total of 15% and 30% of elephant grass in the diet was replaced with a fermented corncob. This study used a Randomized Complete Design, which consists of 3 treatments, each treatment consisted of 4 replicates. The study used 12 male Bali Cattle with an initial average body weight of 226 kg. The cattle were allocated randomly into 3 treatments where cattle received the control treatment R0 (ration with 60% of elephant grass + 10% gliricidia + 10% calliandra + 20% pollard), R1 ( ration with 45% of elephant grass + 15% corncob + 10% gliricidia + 10% calliandra+ 20% pollard) and R2 (ration with 30% of elephant grass + 30% corncob + 10% gliricidia + 10% calliandra + 20% pollard). The results of this study showed that daily weight gain of R0 was 0.61 kg, R1 was 0.61 kg and R2 was 0.62 kg. They were not significantly different (P> 0.05), among the treatments the R0 carcass percentage was 50.29%, R1 was 51.57% and R2 was 51.70%. They were not significantly different (P> 0.05) among the treatments. Fleshing index (FI) each other value of R0 was 1.36, R1 was 1.33 and R2 was 1.29 were not significantly different (P> 0.05) each other. Size of loin eye of R0 = 64.4 cm2 R1 = 64 cm2 and R2 = 64.01 cm2 were not significantly different (P> 0.05) each other. The conclusion of the study was the substitution of elephant grass as a basal diet with fermented corncob for 15% and 30% on the Bali Cattle feedlot were no significant effect on performance and carcass profiles. Substitution of elephant grass with corncob can be done up to 30% on the Bali Cattle feed. Keywords Corncob; Bali Cattle; Elephant Grass;
