Abstract
This study was done to determine feed intake, digestion and growth of weaned Bali calves given native grass, Mulato grass and Mulato grass supplemented with a mixture of rice bran and copra meal. Eighteen male Bali calves approximately 105?4.5 (SE) kg in initial weight and 9 months of age were housed in individual pens and allocated to one of three dietary treatments: native grass (NG) ad libitum, Mulato grass (MG) ad libitum or MG ad libitum supplemented with a mixture of rice bran and copra meal in equal proportions (RBCM) (1% BW/d, DM). The experimental design was a completely randomized block design, there were 6 replicates (animals) per treatment. The experiment lasted for 10 weeks, consisting of a 2 week preliminary (adaptation) period and an 8 week experimental period for measurements. Parameters measured were feed intake, feed digestibility and daily live weight gain. Forall parameters measured, there were significant differences (P<0.05) among the three experimental diets. Bali calves given Mulato grass ad libitum supplemented with a mixture of rice bran and copra showed highest feed intake, digestibility and daily live weight gain, while calves receiving native grass showed the lowest feed intake, digestibility and growth. In conclusion, this study demonstrated that protein contents of the diet dictated feed intake, digestibility, and the growth of weaned Bali calves.
Keywords: Bali calves, native grass, mulato grass, rice bran, copra meal.
