Abstract
AORTIC ruptures in turkeys resulting from dissecting aneurysms were first reported in the United States by Durrell et al. (1952). This was soon recognized to be a major disease problem in turkeys, and was subsequently diagnosed in Canada (McSherry et al., 1954) and Great Britain (Carnaghan, 1955; Gibson and deGruchy, 1955).The cause of the disease is not known; however, fatal dissecting aneurysms in turkeys can be readily induced by feeding beta-aminopropionitrile (BAPN), the lathyrus factor (Barnett et al., 1957).Chicks fed a diet deficient in copper succumb from internal hemorrhages resulting from angiorrhexis (O’Dell et al., 1961). However, low-copper diets did not cause dissecting aneurysm or aortic rupture in turkeys (Savage et al., 1962; Simpson et al., 1963).Pritchard et al. (1958) reported that fatal dissecting aneurysms occurred in male turkeys in a commercial flock which had been implanted with diethylstilbestrol (DES) pellets. Beall et al. (1963) found that…
