Abstract

The efficacy of the perineal stain as an index for sexual maturity and breeding condition in the male greater cane rat, Thryonomys swinderianus, Temminck, was investigated in 34 animals collected from hunters' kills in the Ekumfi District of Ghana, between April and June 1989. The results indicated that, although the presence of the perineal stain was conclusive proof of sexual maturity in an individual, it was not efficacious as an index for sexual maturity for biological work in these animals (p>0.05), because it excluded some that, although sexual mature, did not exhibit the trait, particularly young adults. However, the perineal stain may be useful as a management tool for identifying sexually mature captive greater cane rats. About 7 out of every 10 caught each month were found to be in breeding condition.
