In Indonesia, milk and beef production do not meet the needs. High calves mortality is one of the factors related to the problem. Reducing calf mortality and shortening weaning period are necessary to improve the population and farmers profit. The research was designed to evaluate the effect of inoculation of fiber degrading bacteria during pre-weaning period of dairy calves on nutrient intake and digestibility in post-weaning. The treatments were control and inoculation of bacteria isolates that applied in four and three Frisian Holstein calves, respectively. Both treatments were applied to the calf by a complete randomized design. Variables measured were nutrient intake, dry and organic matter digestibility, and the concentration of ruminal ammonia (NH3) and volatile fatty acids (VFA). Dry matter intake was determined from the beginning of the experimental period. Nutrient digestibility, ruminal NH3 and VFA concentration were determined four weeks after weaning. The data obtained were analyzed statistically using t-test method with α = 0.05. The results showed that the inoculation of bacteria isolates affected the concentration of ruminal VFA of weaned calves. Inoculation of bacteria isolates had no significant effect on nutrient intake, nutrient digestibility and concentrations of ruminal ammonia. It was concluded that inoculation of fiber degrading bacteria into the rumen of calves in milk feeding period improved nutrient fermentability but not improved nutrient intake and its digestibility in post-weaning period.
