Breeding season and breeding potential of the greater cane rat (Thryonomys swinderianus) in captivity in South Africa

Abstract

The cane rat, Thryonomys swinderianus, is an aseasonal breeder. It has a very low fecundity rate with an average litter size of 2.9 (range 1-5), producing a maximum of two litters per annum. The low annual fecundity is the direct result of the extended gestation period of the cane rat which exceeds 150 days in duration.
