One hundred and sixty (160) day old chicks were divided into 8 groups, i-e, A, B, C, D, E, F, G and H each consisting of 20 chicks. Group A acted as non-infected and non-medicated control, B was infected with Eimeria tenella sporulated oocysts on day 16 and 26 @ 20000 per chick and acted as infected control. Similarly, all other members of different groups were also infected at the same rate. Members of Group C were administered toltrazuril orally in drinking water @ 7 mg/ kg body weight on day 18 & 19 and 25 & 26. Members of Group D were given toltrazuril @ 3.5 mg/kg body weight, of Group E @ 1.75 mg/kg as in group C & D, of Group F toltrazuril was given as prophylactic @ 7mg/kg on day 3 & 10. Members of Groups G & H were given irradiated (IEV) and formalized (FEV-48) Eimeria tenella vaccines respectively. IEV was orally given on day 3 & 10 whereas FEV was only given on day 10 of age.
The result indicated that maximum reduction of OPG counts (94.28 %) occurred in members of group D which was given half the dose (3.5 mg/kg) of toltrazuril, Group E (Administered quarter dose) was placed at no.2 and the reduction in this Group occurred as 93.71 %. The group G (IEV immunized) was placed at no. 3 by reducing 89.71 % mean OPG counts as compared to control Group B.
In terms of reduction of OPG counts other Groups were placed at no.4 (Group F given full dose prophylactic), no.5 (Group H immunized with FEV-48) and Group C showed the poorest performance (63.42 %) which was given full dose was placed at no. 6.
In terms of Mean body weight gains as compared to control (healthy) Group A, Group D was placed at no.1, Group E at no.2, Group G at no.3, Group C at no. 4 Group F at no.5, Group H at no.6 and Group B which acted as infected and non-medicated was placed at no.7. Ultimately, it was concluded that toltrazuril @ 3.50 mg/kg or immunization with IEV (irradiated vaccine) would be the best solution to the coccidiosis problem

To find out the therapeutic and prophylactic efficacy of toltrazuril against coccidiosis, an experiment was conducted in the Department of Parasitology, University of Veterinary & Animal Sciences, Lahore.
One hundred and sixty (160) day old chicks were divided into 8 groups, i-e, A, B, C, D, E, F, G and H each consisting of 20 chicks. Group A acted as non-infected and non-medicated control, B was infected with Eimeria tenella sporulated oocysts on day 16 and 26 @ 20000 per chick and acted as infected control.
