Pyrrolizidine Alkaloid content and seed toxicity in Crotalaria species
Crotalaria spp.Have been reported to contain various pyrrolizidine alkaloids (PA) in the seeds.Sunn hemp (C.J uncea) is a summer legume with the potential to be valuable as animal fodder in late summer in the Southeast, USA (Mansoer et al.1997).It has been reported that sunn hemp seeds contain pyrrolizidine alkaloids ( PA) that have toxic effects on some farm animals such as pigs (Zhang,1985).However,other researchers have reported that seeds can be fed to farm animals with no toxic effects.Rotar and Joy (1983) determined that seeds of cultivar Tropic Sun were not toxic.Chicken have been reported to be the most sensitive animals to PA.The presence and quantity of PA in several populations were determined and the effect of including sunn hemp seed in the feed on chicken mortality was evaluated.
