Breeding and rearing squirrel monkeys (Saimiri sciureus) in captivity.
A breeding colony of squirrel monkeys (Saimiri sciureus) was established to provide animals for behavioral research concerned with early development. The origin of the initial breeders was Peru, Colombia, and Bolivia. During the past 10 years, the colony has grown to 125 adult females, 20 adult males, and 120 immature animals of various ages. The annual conception rate for the last 5 years averaged 68%. This resulted in 84% viable births of which 82% survived past 6 months of age. The majority of the births (65%) occurred during June-August, and 87% during May-September. The most efficient and successful breeding strategy was to form mixed-sexed groups of 10--15 females and 2--3 males before the mating season began and to maintain the integrity of these groups with minimal interference. Progeny were reared apart from their natural mother without difficulty, and their growth and development were found to be similar to those of mother-reared monkeys.
