+-?kg and aged between 90 and 150?days, were used. Animals were submitted to an experimental period of 112?days. The experimental treatments consisted of: control-?mineral mixture only, plan 1-?high protein and high carbohydrate multiple supplement, plan 2- high protein and low carbohydrate multiple supplement, plan 3-?low protein and high carbohydrate multiple supplement, and plan 4-?low protein and low carbohydrate multiple supplement. About 25 and 12.5?% of the protein requirements were supplied by the high and low protein supplements, respectively, and 15 and 7.5?% of total digestible nutrient requirements by the high and low carbohydrate supplements, respectively. Grazing behavior, performance, milk production, milk composition, intake, and digestibility of the cows were not affected (P-gt;-.05) by the supplementation of the calves. The supplemented calves had greater (P-lt;-.05) performance (as measured by final body weight, average daily gain, and final body condition score), intake and idle time, and lower (P-lt;-.05) grazing time, but supplementation did not affect (P-gt;-.05) suckling time and suckling frequency. It can be concluded that supplementation affects the behavior and feed intake of calves. However, it does not affect the suckling time and suckling frequency of calves. Additionally, performance, milk production, nutritional characteristics, and behavior of their dams are not affected." />
