Abstract: The aim of this study was to evaluate intake, digestibility, ingestive behavior and performance of Boer × non-descript breed F1, Canindé, and Moxotó kids subjected to three levels of feeding (ad libitum or intake restricted by 25 or 50%). The study used 45 non-castrated males, 15 animals from each genetic group, assigned to a 3 × 3 factorial arrangement, with 5 replicates of each genetic group at each feeding level. There was an interaction (P<0.05) between genotype and feeding levels for intake, digestibility and average daily gain (ADG). There was no effect (P>0.05) of genotypes and no interaction between feeding levels and genotypes for parameters of ingestive behavior. At the level of ad libitum intake, Boer × NDG F1 animals showed higher dry matter intake and ADG, and lower dry matter digestibility compared to the Canindé and Moxotó, respectively. Kids at the 50% restriction level had a longer rumination time per gram of dry matter ingested (0.76 min/g) compared to those fed ad libitum (0.29 min/g) and with 25% restriction (0.41 min/g, P<0.05). Boer × NDG F1 animals, when fed ad libitum, have higher performance than Canindé and Moxotó. Kids subjected to feed restriction have a longer rumination time.
