| Abstract | ||
| This study was conducted to examine field cases of mycotoxicosis (A flatoxicosis and ochratoxicosis) and their effects on calcium during the preproduction period of 1SA brown pullets. Birds were 12-15 weeks of age. The feed was subjected to analysis for mycotoxin and blood samples were laboratory diagnosed for infectious bronchitis and infectious bursal viruses antibody titer and for determination calcium level. Clinical signs of affected birds were rubbery bone, ruffled feather, paleness and high mortality. Necropsy findings of sick birds were characterized by muscle dehydration, enlarged livers yellowished, kidney enlargement and urate deposition. Histopathological features of liver consisted of capsular thickening hepatocellular necrosis, subcapsular infiltration with inflammatory kidneys cells showed swelling of tubular cells, deposition of calcium between kidney tubules with infiltration of inflammatory cells. ELISA test revealed the presence of 800 ppb aflatoxin and 100 ppb ochratoxin. Normal titers of infectious bronchitis virus and infectious bursal diseases antibodies were recorded. Low blood calcium level of 8.2 mg/dl was registered in the tested blood samples. | ||
