Abstract   

    The present project was designed to detect the stress following vaccination (Eimeria vaccine) against coccidiosis in broilers and its management by using multivitamins and aspirin. The parameters studied were heterophil/lymphocyte ratio, total serum protein, serum glucose and serum cholesterol estimation, for three consecutive post vaccination days. At the end of experiment, on 42nd day, adrenal gland/body weight ratio and histopathology of adrenal gland was performed to assess any change. The results showed no statistically significant differenc among difference groups. However, the group that was given multivitamins showed maximum weight gain and minimum stress, while the aspirin therapy did not show any significant difference.

Key words: Stress, vaccination, and coccidiosis, Eimeria
