Abstract
Six Holstein steers, with an average body weight of 204 kg, were assigned to three diets containing 0 (control), 30 and 60% steamed birch (Betula platyphylla uar japonica; treated at 180°C for 20 min and fiberized). The trial was designed for two periods of 18 and 13 weeks. Daily dry matter intake and ratios to body weight were 8.59, 2.55%; 9.94, 2.82% and 10.21 kg, 2.61%, respectively, for diets containing 0, 30 and 60% steamed birch. A growth curve, produced by plotting body weight against age, changed linearly for each steer; daily gains were 1.23, 1.34 and 1.32 kg for diets containing 0, 30 and 60% steamed birch respectively. There was no significant difference in feed intake/gain among the three diets. There were no significant differences in pH, VFA concentration, VFA molar proportion and total protozoa count in rumen fluid among the three diets. The proportion of acetic acid in rumen fluid was about 70% for each diet. The presentexperiment indicates that steamed birch can be used as an energy source in the diets of steers.
