RESUMO
Currently the pig industry has undergone several adaptations, since the consumer is becoming more selective, especially with regard to food safety and animal welfare. Europe, the major consumer market of Brazilian pork, prohibits the practice of removing or wearing down of the teeth of piglets during the maternity, justifying this practice discourages the welfare of animals. On the other hand, in Brazil, this practice is still being performed routinely in most pig farms, which impairs the exportation of swine products to demanding markets. There is insuficient information about the harms and benefits of that management, so this study aimed to evaluate the influence of dental activity management on the performance of piglets during nursery. Twenty-six litters randomly distributed according to the order of birth of mother were investigated, being 13 litters subjected to dental management (control group), and 13 litters not subjected to the same management (treatment group). Each litter was evaluated for 21 days, undergoing piglets weighing on the day they were born and at 21 days occurred when weaning, thus to obtain the variables average daily weight gain (ADG) and weaning weight (WEIGHT). Regarding the ADG of piglets, the control group showed an average gain of 0.193 kg/day while the treatment group showed 0.200 kg/day, with no significant difference (P>0.05) between the ex
