Pemberian Ransum Berenergi Tinggi Memperbaiki Performans Induk dan Menambah Bobot Lahir Pedet Sapi Bali (PROVISION HIGHER LEVEL OF ENERGY RATION IMPROVE CATTLE PERFORMANCE AND CALVES BIRTH WEIGHT)

This study aimed to determine the effect of energy levels in bali cattle rations of seven months pregnant on birth weight calves. The study was conducted in Farm Sobangan Badung Regency on 12 pregnant breeding phase of pre-calving (two months before the birth) with the parent body weight at average 300 kg/head. The treatments were four types of rations which was iso protein 10% with the energy level were 2000, 2100, 2200 and 2300 kcal ME/kg respectively. Variables measured were: weight gain, consumption of dry matter (DM), organic matter (OM), consumption energy, crude protein (CP) and crude fiber (CF), and birth weight calves. The design used was a randomized block design. Results showed DM intake varied from 5175.80 to 5366.80 g/d. Consumption of OM ranging from 4438.54 to 4610.44 g/d. Calf birth weight was also highest in the parent with treatment D is 18 kg. All these differences were not statistically significant (P>0.05). Energy consumption significantly highest (P <0.05) at the treatment D i.e. 19320.65 kcal GE/d. The conclusion of this study is energizing ration of 2000 - 2300 kcal ME/kg increase energy consumption however, improve performance seven months pregnant Bali cattle and calf birth weight to add into 18 kg.
