Abstract
Gender plays an important role on deposition rates of different body tissues and due to the variation in the composition of gain, net protein requirements can differ between males and females. Souza et al. (2012) reported that bulls had greater protein requirements than castrated males, which were greater than females at the same age because intact males showed greater lean tissue deposition in the body than castrated males and females. In dairy goats, only a few studies dealing with the effect of gender on protein requirements have been published. Thus, the objective of this study was to determine the net protein requirements for growth of intact males, castrated males, and females Saanen goat kids using comparative slaughter technique.
