Abstract

In order to achieve the main objective of our research is to prove that rabbits possess rectal glands
not anal glands. Our work was carried out on fifteen healthy adult New Zealand rabbits
(Oryctolagus cuniculus) of both sexes and with variable ages. The glands were macro and
microscopically examined. Also the measurements of the gland and the rectum (length/cm) were
obtained. The rectal glands were elongated oval in outline and present on the lateral sides of the
rectum and ended at the anorectal junction. Microscopically, the rectal gland was merocrine in
nature and divided into many lobules that composed of different exocrine secretory. The ducts of
the gland were numerous in the anterior two third and were scanty in the posterior one third
