Reproductive performance of three species of Callitrichidae.
The reproductive performance of three species of Callitrichidae housed under identical conditions, including relatively spacious caging and visual screening, was compared. The three species were Callithrix jacchus, Saguinus fuscicollis, and Saguinus oedipus. Callithrix jacchus was the most reliable breeder, with the lowest percentage of stillborn and the highest post-weaning survival. While the reproductive performance of S oedipus was better than that generally reported for other colonies, the reproductive performance of the Saguinus species was still poorer than that of C jacchus. The two Saguinus species did not differ significantly in either percentage of stillborn or post-weaning survival. None of the species showed infertility due to lactation, but the mean inter-birth interval was significantly longer for S oedipus than for either C jacchus or S fuscicollis.
