Anti-coccidial effects of dietary chamomile against experimentally induced coccidiosis in broiler chicken

A 4 × 2 factorial experiment was conducted to investigate the effect of dietary supplementation levels (0, 5 and 10 g/kg) chamomile flower powder a level (60 mg/kg) salinomycin on performance gut health broiler chickens under coccidiosis challenge. total 320-day-old Ross 308 broilers were assigned eight treatments four replicates with 10 birds. Oral inoculation challenged groups Eimeria tenella occurred day 8. On 10, disease challenge additive significantly (P = 0.003) interacted, decreasing feed intake. Feed intake ≤ 0.001) decreased in birds supplemented g/kg chamomile. At 35 days, fed anticoccidial increased body weight (BW) gain (WG). Disease adversely influenced BW WG. Additive interacted conversion ratio (FCR). Anticoccidial improved = FCR regardless rearing conditions.

Chamomile could be used as potential natural nutrition.
