Differential investment by female coypus (Myocastor coypus) during lactation

Differential investment by female coypus (Myocastor coypus) during lactation

Physiological strategies in lactation The Proceedings of a Symposium held at the Zoological Society of London on 11 and 12 November 1982: 273-300

This review of a long-term investigation of feral coypus (nutria) includes an account of work on 20 wild-caught, pregnant females kept in captivity until they littered. The surviving male offspring were about 8% heavier than females at birth (males, 224+or-44 g; females, 208+or-47 g). Lactation, which lasted for 7.7+or-1.0 wk in the wild, lasted for 10-14 wk in captivity. The food consumption of a sample of lactating females was 63% higher than that of non-lactating females.
