The promising preparation against coccidial oocysts in poultry
The effectiveness of different concentrations of preparation Virukill 260 against sporulated coccidial oocysts in Cobb-500 broiler chicks since 14 days of age was studied in comparison with the recommended concentration of phenol. The efficiency of elimination of sporulated Eimeria spp. oocysts for the concentrations of the preparation 0.5; 1.0 and 2.0% was 94.15; 97.60 and 98.17%, respectively, while phenol (4%) resulted in elimination efficiency 88.75%. Broilers from infected control treatment infected with sporulated coccidial oocysts (2,000 per 1 mL of the suspension not treated with disinfectants) excreted large amounts of oocysts (average 64,880 per 1 g of feces) at all studied ages. As a result the bodyweight gain from 14 to 34 days of age in this treatment was significantly lower by 26.58% in compare to non-infected control treatment.
