Title : Some aspects on the anatomy of the uterus neck of the «Baudet du Poitou» donkey breed
Authors : C. GUINTARD, O.M. VENDRAMINI et D. TAINTURIER.
Summary : The authors measured the uterus neck of 30 female donkeys of pure «Baudet du Poitou» breed and of cross-breeds. The length of the neck, its cranial diameter, its caudal diameter and the position of the caudal ostium with regard to the the base of the vagina allowed to define two morphological indexes : the index of «dilatation-lengthening», and the index of « oestral modification». The analysis according to age and height class (height at withers) shows differences between, on the one hand, small and often old animals which are cross-bred, for which the uterus neck is long, little dilatable and shows little modification between dioestrus and oestrus, and on another hand younger and taller animals which have a smaller uterus neck and which present stronger indexes. The anatomy of the uterus neck of the donkey differs from that of the mare, not only by its size but also by the existence of an important vaginal eminence and by the presence of clear mucosal folds which are connected to the «open flower arrangement» of the caudal part of the uterus neck and form dorsal and ventral frenulums with respect to the latter.
