Experiment was conducted to determine the effects of supplemented soy flour in mild replacer on performance of dairy calves. Twenty crossbred Holstein-Friesian male calves were randomly divided into 5 treatments based on Completely Randomized Design: 1. milk replacer 2. milk replacer + 10 percent soy flour 3. milk replacer + 10 percent soy flour + 0.1 percent Methionine 4. milk replacer + 20 percent soy flour 5. milk replacer + 20 percent soy flour +0.1 percent Methioine. The experimental period was 70 days.The results showed that there were no significant different in average daily gain, feed per 1 kg gain, weaning weight and DM. intake among the soy flour supplementation groups and control. However, supplemented soy flour in milk replacer tended to decrease average daily gain, but increase feed per 1 kg gain Amino acid supplementation improved growth performance in groups fed with replacer supplemented with soy flour. Total feed cost was significantly lower among soy flour supplementation groups than control (P LT 0.05) cost per 1 kg gain was not significant difference. The groups fed with milk replacer supplemented soy flour at 10 percent and 0.1 percent Methionine gave lower feed cost per 1 kg gain.
