Abstract
The objective of this study was to investigate the anticoccidial effect of apple cider vinegar
added to drinking water with the anticoccidial effect of amprolium to feed broiler chicken.
The study has adopted an observational approach to evaluate the anticoccidial effect of apple
cider vinegar on broiler chicken. The antioxidative changes were measured adding natural apple
cider vinegar to drinking water. Four hundred and fifty broiler chickens were purchased from the
local market and distributed into three groups (T+vc: positive control, T-vc: negative control Tv:
apple cider vinegar) with 150 chickens in each group. The three groups were further replicated
into 3 blocks each containing 50 chickens. The groups were fed balanced diet, amprolium was
added to the feed of positive control group, and apple cider vinegar was added to the water of
Tv group. Measurements of the different variables were started from week 3, at the end of each
week 3 birds were chosen randomly, blood samples were collected via the wing vein, and fecal
oocysts were counted from intestinal contents of each individual bird using the McMaster
technique. Broiler in the control groups T+ve and T-ve showed clinical signs of coccidiosis (blood
in feces) and the number of coccidial oocytes in feces increased with time. In the vinegar group,
no clinical signs of coccidiosis were observed. Concentrations of total antioxidants and catalase
enzyme activity significantly increased (p≤0.05); while malondialdehyde concentration significantly
decreased (p≤0.05).
