The donkey cervix may be predisposed to the development of pyometra, as it is longer than the cervix in the horse mare and protrudes into the vagina (Vendrammi et al 1998; Pugh, 2002). This makes drainage of the uterus difficult. There is also a reference in the literature to removal of a uterine tumour in a donkey mare (Bonfig and Ingenhorst, 1992). | The donkey cervix may be predisposed to the development of pyometra, as it is longer than the cervix in the horse mare and protrudes into the vagina (Vendrammi et al 1998; Pugh, 2002).
