The developmental toxicity of cottonseed extraction on chicken embryo

Cottonseed meal is widely used as one of the protein supplement in poultry diets. Its mechanism of toxic action on chicken embryo is poorly understood. In this study, direct effects and abnormalities of cottonseed on chicken embryo were studied. Oxidative stress, cholinergic stress, mineral analysis and microscopic lesions were analyzed in chicken embryo which injected cottonseed extraction in 0.1, 1 and 10 mg concentration (with free gossypol 0.25 ppm, 2.5 ppm and 25 ppm respectively) at day 4 of incubation. Higher group had 100% mortality. Serum of alive chicken embryo at day 20 of incubatio...
