The present study was designed to compare the efficacy of different anticoccidials available in market. Coccidiosis is a disease of universal importance in poultry production. A total of one hundred and eighty, day old broiler chicks were purchased and raised for 42 days in a healthy and good hygienic environment. The birds were then divided into 6 groups viz A, B, C, D, E and F having 30 birds each. Group C and D was given feed additive anticoccidial Kokcisan (salinomycin 12%) and Decocci (meduramycin 1%), while in group E and F was given a herbal drugs i.e. Urisool and Coxigon respectively. All the groups except group E were given challenge of infection on day 22. The oocyst count was done on 5th, 6th and 7th day after infection.

During the experimental period feed intake, weight gain, FCR, mortality rate, oocyst count, clinical findings and postmortem findings were recorded on weekly basis. Results showed that average feed intake was higher in group E i.e. infected and treated with Urisool (herbal coccidiostate). The result showed there is no statistical difference between herbal coccidiostates and other chemotherapeutic drugs. Average weight gain was higher in group E i.e. infected medicated with Urisol a herbal product gave better result.

The results of present study showed that salinomycin treated group is better among all groups regarding FCR. The herbal groups showed less percentage of mortality. The results are also in agreement with many scientists who reported that herbal anticoccidials are safe and has no side effects and tissue destruction. No toxicity and poisoning is observed even at higher doses as in ionophores and no resistance is developed towards any species of Eimeria. Oocyst count was also lower in both herbal treated groups. Almost all the birds receiving infection showed the clinical symptoms of coccidiosis, symptoms were more pronounced in birds of group (uninfected and unmedicated), salinomycin and meduramycin treated group. However, in groups treated with Urisol and Coxigon the signs were not much pronounced, which shows effectiveness of herbal preparations. On account of all these results, it is summarized that herbal anticoccidials are equal in efficacy as compare to other anticoccidials.

The results of this study will help to the feed millers in choosing best and economical feed additive anticoccidial.
