Abstract
Extract
Prior to 1960, carcinomas of the intestine of sheep had been reported only rarely. Dodd Citation(1960, Citation1964) reported a total of 51 cases of carcinomas of the ovine small intestine in material passing through a New Zealand diagnostic laboratory over a period of 7 years. Six of the 88 “wasting” sheep examined by Cook Citation(1964) in New Zealand were affected by “neoplasia of the intestine”. The common occurrence of small intestinal carcinomas in ewes in New Zealand was confirmed by Webster Citation(1966, Citation1967) who found lesions in 0.52% of slaughtered ewes, and in approximately 0.02% of hoggets and wethers. No cases were noted m over 200,000 slaughtered lambs.
