The pathologic studies on the cottonseed meal poisoning in chicken were performed by feeding a diet containing 50 per cent cottonseed meal. The results obtained are summarized as follows: The specific effect of cottonseed meal on chicken was apparently limited to the parenchymatous tissue and blood vessels, where its major pathologic manifestations were degenerative changes in acute cases fed for a period of 7 days, while necrosis of portal and central veins of liver and consequent perivascular hemorrhage and coagulative necrosis of liver and intra-glomerular hemorrhage were characteristic lesions in chronic cases fed for a period 20, 40 and 60 days. In addition, specific cottonseed pigment cells were observed in small number in villus of small intestine in acute cases and in large number in villus, liver and spleen in chronic cases.
