Abstract


Late-weaned practice is common in Indonesia and this contributes for longer calving interval. Lack of milk is the main reason why famiers let their calves with the cows for longertime. Twenty seven 28 days old Bali calves were divided into 2 groups of 13 (Group A) and 14 (Group B). Animals in Group A were offered with I2 % live weight (LW) chopped Elephant grass and 6% LW mix legume leaves (Gliricidin : Leucancna : Calliandra at a ratio of 60 Z 30 : I0) (Diet A). While animals in Group B (Diet B) were offered 0.2 kg/hd/day molasses and cassava 0.3 kg/hd/day) on top of Diet A. Water was available at all time and the trial was
terminated when calves reached 168 days old. Supplementation of molasses and ground cassava significantly improve body condition score (5.8 vs 5.2) and market price (Rp 244.000,- vs Rp 200.000,- (P<.05). While mortality rate was significantly lower (43 % vs 52%). Animals in the supplemented Group (B) Had higher live weight (39 kg vs 31 kg) and higher average daily live weight gain (142 vs 116 g/day), however they were not significant (P>.05). This may be due the limited number of calves used in this study. It is suggested that complete supplementation
should be given to calves in order to support early weaning practice for calves.
