Supplemental feeding of marmoset (Callithrix jacchus) triplets.

In a colony of marmosets (Callithrix jacchus), all fifteen infants from five sets of triplet births were successfully reared with their parents. Two supplemental feedings were given each infant daily. As an alternative to hand-rearing or foster rearing, the supplemental feeding method eliminated the time-consuming process of hand caring for an infant on a 24-hour per day basis.
