ABSTRACT
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 percent mortality. Serum of alive chicken embryo at day 20 of incubation were measured for FRAP (ferric reducing ability of serum), total SH groups assay, cholinesterase assay and potassium concentration. The results expressed as mean±SD show to increase oxidative stress, cholinergic stress but significant difference (p<0.05) wasn't observed between groups. The significant difference was observed in potassium concentration in serum. Some evidence of hematotoxicity such as hemorrhage and higher number of puntate reticulocytes were detected. It is concluded, hematoxicity and hyperkalemia are toxicity mechanisms that could initiate in low concentrations of cottonseed in chick embryo.
