Gossypol, a secondary plant compound found in cotton (Gossypium spp.), is known to be toxic to a variety of animals, particularly monogastric mammals and birds. Because ruminants are resistant to gossypol, whole cottonseed and cottonseed meal have been used as a feed supplement for many decades. Concerns over gossypol toxicity arise because of its presence in cottonseed products, particularly livestock and wildlife feed. The concentration of cottonseed in the environment near livestock and wildlife feeding stations presents the possibility that it may be ingested in significant amounts by non-target wild animals, resulting in inadvertent gossypol dosing. A species of significant economic and cultural value is the Northern Bobwhite (Colinus virginianus). However, there are no published data regarding if Northern Bobwhites would consume cottonseed meal given the opportunity. We assessed selection for or against cottonseed meal by performing a dietary preference study. Birds (n =120) were given the choice between commercial game bird feed, scratch grains, and cottonseed meal containing 0.74% total gossypol. We measured feed consumption for five days. The birds’ diet consisted of 51.74% game bird feed, 37.72% scratch grains, and 10.54% cottonseed meal, and percentages varied significantly among all feed types (P≤0.001, n =360). We concluded that Northern Bobwhites selected against the cottonseed meal in favour of the game bird feed first and the scratch grains second. Our results suggest that given the choice, Northern Bobwhites will select against cottonseed meal if other feed choices are available.
