Research in reproductive physiology of the indigenous goat in Uganda

Oestrous cycles have been studied in mature does and pubertal animals of the small East African goat in a management system with peasant farmers in Uganda. Forty-seven percent (47%) of the cycles were of normal length of approximately three weeks. Thirty percent (30%) of the cycles were short being of a duration of two weeks or less. Twenty three percent (23%) of the cycles were very long being of duration of two cycles or higher multiples. These were deemed to be due to silent heat. The endocrinological basis of the variation of the reproductive cycles and the possible consequences of infertility have been discussed. In the doe acceptance of coitus during pregnancy has been found to be fairly common
