Abstract

In order to evaluate the influence of crude protein levels in the diet over the sexual maturity age, 60 partridges Rhynchotus rufescens Temminek (Aves, Tinamidae) were fed 5 different crude protein levels according to the bird's age. The results show a difference (p < 0,05) among treatments for the age at first lay, which confirms the increased earlier sexual maturity in heavier birds, although no difference was observed in the treatments for the number of eggs produced. The average age at sexual maturity of 302 days, close to other birds with the same kind of exploration, shows that this species deserves further studies in order to improve its reproductive levels.
