In order to study the signs of œstrus in the West African Dwarf goat, 28 non pregnant females younger than 24 months of age were used. Most of them (94.7%) had waggled the tail during heat. The frequency of micturition was higher in the presence of the male. The swelling of the vulva was observed in 68.4% of goats in heat. The cervico-vaginal mucus was significantly (P≤0.05) abundant and elastic during œstrus. The duration of œstrus was 1.91± 0.07 day and increased with the female age.Signs of heat were less prominent in younger than in older females. Behavioural changes, vulva appearance and the characteristics of cervico-vaginal mucus can be used as criteria for detection of œstrus inthe West African Dwarf goat.
