Evaluation of the effectiveness of alternative methods for controlling coccidiosis in broiler chickens: a field trial

Abstrakt

Currently, coccidiostats are the primary and standard method of combating coccidiosis in poultryfarms. However, consumer organizations still point to the need to phase out all chemotherapeuticsubstances from animal nutrition to protect human health. The research material consisted of 720cocks of the Cobb 500 hybrid, which were divided into three groups (C – coccidiostat/control, V– vaccine, and H – herbals). The following parameters were analyzed: body weight (BW), feedconversion ratio (FCR), mortality, foot pad dermatitis (FPD), European Production EfficiencyFactor (EPEF), and the number of oocysts per 1g of feces (OPG). On day 42, the BW of the C groupwas higher compared with the V and H groups. The C group was also characterized by the best FCRand the highest EPEF. In the V group, oocysts were noted in feces from the 14th day of rearing, andthe highest oocysts content was observed on the 21st day of life. In the C and H groups, the highestnumber of oocysts was recorded in the feces on the 28th day. The investigated alternative methods tococcidiostats showed good antiparasitic potential. Therefore, combining a couple of anticoccidiosismethods in preventive programs may be the best solution in broiler chickens production.
