<![CDATA[Database of Bali heifer particularly on their nutrient digestibility, energy and nitrogen balance of various ration formulas on their growth performance were limited. A randomized block design with four types rations of metabolizable energy (ME) and crude protein ratios, i.e. of 2,045.38 kcal ME/kg:12.06% (Treatment A), 2,103.57 kcal ME/kg:13.11% (Treatment B), 2,201.85 kcal ME/kg:13.97% (Treatment C) and 2297.60 kcal ME/kg:15.05% (Treatment D) were conducted to evaluate nutrient digestibility, energy and nitrogen retention of Bali heifers. The rations consisted of concentrate, urea, molasses, king grass, coconut oil and vitamin-mineral mix. Results showed that Treatment D improved significantly of the 7,814.34 kcal/d digestible energy, 49.87 g/d digestible nitrogen, 11,015.06 kcal/d energy intake, 423.53 g/d nitrogen intake, 67.76 kcal/d energy retention, 7.91 g/d nitrogen retention, 0.33 kg/d daily weight gain (ADG), (P<0.05). In summary, ration for Bali heifer should contain at least 2,297.60 kcal ME/kg:15.05% crude protein for better average daily weight gain.]]>
