Abstract
114 three-day-old broiler ducks were made experimental Cd poisoning.LD50 of acute Cd poisoning was 289mg/kg body weight.Subacute Cd poisoning was with 1/10,1/20,1/30LD50,morbidity and mortality were 11/11,11/11,3/11 and 10/11,7/11,3/11 respectively.Clinic symptoms of the affected ducks appeared as anemia(Hb,RBC,PCV,P<0.05 or P<0.01),reduced growth (P<0.05 or P<0.01),dyspea and nervous sign.Pathologic lesoins of acute dead cases showed gastroenteritis,gallbladder expansion,degeneration of liver and kidney,hyperaemia and hemorrhge of brain.Pathologic lesions of subacute dead cases were characterized by fibrinous epicarditis,fibrinous perihepatitis,fibrinous pleuritis and air sac edema and calcification.Degeneration and interstitial inflammation of liver and myocardium,pneumonia and catarrhal gastroenteritis were also evident.Ultrastructural changes showed that mitochondria in cardiac muscle fibers,liver cell and kidney epithelial cells were swollen with disintegration and lysis of cristaes.Cd contents of the liver and kidney in the control group compared with the Cd adding experimental groups were significant(P<0.01).关键词
