Effectiveness of Joint Administration of an Anticoccidial Drug and a Biogenic Stimulant Against Spontaneous Coccidiosis of Broilers in a Farm Scale Trial

The research conducted in our country and abroad has proven that any poultry farm that practices poultry floor management is affected by parasitic diseases, especially eimeriosis. The purpose of this study was to test the effectiveness of joint administration of the anticoccidial drug Diclazuril and the biogenic stimulant ASD against spontaneous coccidiosis in broiler chickens under production conditions. The effectiveness of joint administration of Diclazuril was tested on 1,739 floor management chickens aged 9 to 38 days, at a dose of 2 mL per 1 L of drinking water for 48 hours according to the following scheme: on day of age 9–10; 16–17 and 24–25, and the biogenic stimulant ASD in a dose of 20 mL per 1 L of drinking water for 72 hours according to the scheme: on day of age 9–11; 15–17 and 23–25. The control chickens were given the recommended dose of Amprolium with water. The prevalence and intensity of Coccidia infection, as well as the intense-effectiveness of joint administration were determined based on results of coproscopic examinations of 30 litter samples from each group. The joint administration effect on the weight gain of the broilers was studied on 60 chickens that were individually tagged and weighed at 9 and 38 days of age. The farm scale trial results showed that the intense-effectiveness of the joint administration of Diclazuril and the biogenic stimulant ASD against spontaneous coccidiosis in the broiler chickens was 93.5%, and this had a positive effect on the productivity of the broilers that had their average daily weight gained by 11.5% compared to the control group.
