Abstract

A histological study of New Zealand White female rabbits’ ovaries was undertaken. Rabbits were fed on canola meal as an increasing substitute (00, 33, 66 and 100%) for soybean meal so that the tissue’s general aspects could be verified and the number of ovarian follicles from each experimental group could be obtained. Forty-eight female rabbits were slaughtered at 43, 150 and 225 days of age and their ovaries were fixed in Bouin’s liquid, washed and conserved in 70% ethanol and embedded in paraffin. 5µm-thick histological sections were undertaken and stained by HE and Azan techniques. The ovaries were bound by a predominantly simple cubic epithelium followed by the tunica albuginea. Ovarian follicles were observed in different stages of development in the cortical tissue. Interstitial gland cells, blood and lymphatic vessels and nerves were observed in the medullar tissue. Small cysts were also reported. Histological preparations didn’t show any change between groups either in the general morphology of the tissue or in follicle number. This fact suggests that the use of canola as a food of rabbits didn’t interfere in reproduction.
