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

Currently, coccidiostats are the primary and standard method of combating coccidiosis in poultry farms. However, consumer organizations still point to the need to phase out all chemotherapeutic substances from animal nutrition to protect human health. The research material consisted of 720 cocks 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), feed conversion ratio (FCR), mortality, foot pad dermatitis (FPD), European Production Efficiency Factor (EPEF), and the number of oocysts per 1g of feces (OPG). On day 42, the BW of the C group was higher compared with the V and H groups. The C group was also characterized by the best FCR and the highest EPEF. In the V group, oocysts were noted in feces from the 14th day of rearing, and the highest oocysts content was observed on the 21st day of life. In the C and H groups, the highest number of oocysts was recorded in the feces on the 28th day. The investigated alternative methods to coccidiostats showed good antiparasitic potential. Therefore, combining a couple of anticoccidiosis methods in preventive programs may be the best solution in broiler chickens production.
