Abstract

Measurements have been made of the length and diameter of the cervix and caudal ostium position in relation to the vaginal floor in 30 jenny asses of Baudet du Poitou breed and crosses. These measurements were obtained on the 4th, 5th and 6th days of oestrus and the 6th and 8th days of dioestrus. The observed anatomical modifications were mainly associated with the animal's physiological state, age and morphological type (size). The cervical anatomy of the female donkey differs from that of the mare not only in size but also in the existence of a large cervical protrusion into the vagina which can lead to the occurrence of cervical lesions during parturition or from the mechanical action of mating, especially when the female is small. This anatomical conformation also makes intrauterine ejaculation difficult whether by natural service or by artificial insemination.
