A study was conducted at to evaluate the prophylactic efficacy of salinomycin against coccidiosis in commercial quail t broilers (during January- February 1999). For this purpose, two groups comprising 90 commercial Quails (day-old) and 90 broilers (day-chicks) purchased from a local hatchery were reared under controlled management and coccidiosis-free condition for 42 days of experiment. Two groups were further divided into six sub-groups i.e., A1, B1 and C1 indicating quails and A2, B2, and C2 for broilers of 30 birds in each sub- group Birds in group A and A were kept as non-infected control group. The chicks of group B1, B2, C1 and C2 administered with virulent sporulated oocyst of Eimeria tenella and birds in group C1 and C2 were fed Salinomycin sodium in their feed throughout the experimental period. The birds in group A1 and A2 showed no clinical signs of coccidiosis, highest (110 and 1517 gms, respectively) body-weight gain and no mortality record throughout the experimental period. While the birds in other groups i.e. B1, B2, C1 and C2 showed varying clinical signs, low body-weight g, (90, 1110, 105 and 1408 gms, respectively), diarrhea containing oocyst of E. tenella (15457, 22728, 1265 and 12528 per gram of faeces, respectively) while mortality was 30%, 20%, 6% and 10%, respectively. It is concluded that salinomycin worked against coccidiosis in two groups i.e., C1 and C2 (quail and broilers) because these groups showed lower clinical signs, lower mortality and higher weight gain than no treated groups (B1 and B2).
