The aim of the present study was to evaluate the anthelmintic efficacy of three commercial compounds against ascarids and Capillaria spp. in naturally infected fighting cocks from Mexico. First experiment.- Forty cocks were selected on the basis of eggs per gram (EPG) counts quantified by the McMaster method. On day 0 the birds were divided into four groups of 10 cocks, each subjected to the treatments. Group 1 received a single oral dose of 1 mg of ivermectin, 25 mg of praziquantel and 40 mg of fenbendazole given in tablets according to body weight (b.w). Group 2 was treated with a single oral dose of 1 mg of ivermectin, 25 mg of praziquantel and 40 mg of fenbendazole given in tablets/b.w. but formulated with a different excipient. Group 3 received a single tablet containing 0.2 mg of abamectin and 30 mg of albendazole. Group 4 served as a non-treated control. Fecal analyses were carried out on days 0 (day of treatment), 7, 14, 21 and 28, being collected from the floor where the cocks were individually caged. Efficacy was measured on the percentage of egg reduction from day 0 with respect the EPG counts from the control group. In a second experiment the study was similarly performed using another cock-farm located at approximately 300 km away from the first one. Results indicated an overall efficacy of 100%, 94.0% and 100% for groups 1, 2 and 3 in the first experiment and 100%, 100%, 100% for groups 1, 2 and 3 of the 2nd experiment, respectively. It is concluded that all drugs used exerted high efficacy in fighting cocks naturally infected with helminths.
