Estimation of energy and protein requirements for Korean native heifers. 1. Estimation of energy and protein requirements for Korean native heifers by metabolism trial


Korean Journal of Animal Sciences 34(5): 293-300
Estimation of energy and protein requirements for Korean native heifers. 1. Estimation of energy and protein requirements for Korean native heifers by metabolism trial
Native Korean heifers were fed on diets containing rice straw and concentrates to achieve target daily gains of 0.2, 0.6 and 0.8 kg (T1, T2 and T3, respectively) at 150-200, 200-250, 250-300 and 350 kg body weight. Average daily gain (DG) was 0.30 (T1), 0.62 (T2) and 0.67 kg (T3), respectively. Except for crude fibre, digestibilities and nutritive values of the diet were increased with increasing DG.
