In the first trial, the influence of two levels of intake (825-842 vs 935-936 g of DM) of acidified milk replacer and of two administration periods in buffalo milk (lower than 10 vs 20 d) on the intake and growth rate of 53 buffalo calves, from 10 and 60 days of age were evaluated. Dry matter intake depended on the dry matter content of the acidified milk replacer and not on that of hay plus concentrate. Feeding costs were higher for calves fed for 20 d with buffalo milk and for those that had the highest level of acidified milk replacer DM intake; the latter also showed a higher weight gain. In the second trial the effects of weaning begun at 45 d (with a reduction of 31% of acidified milk replacer DM) were assessed. In the period 10-60 d of age, this technique decreased daily feeding costs but did not reduce the cost of weight gain unity. Dry matter intake, until 45 d of age depended on the DM of the acidified milk replacer; in the 45-60 d period the calves given less acidified milk replacer showed a daily intake similar to the controls. Between 60 and 80 d of age the subjects that were weaned gradually transformed dry matter better than subjects weaned brusquely at 60 d.
