摘      要：Background:Due to presence of drug-resistant Eimeria strains and raised public health safety concerns about drug residues in the meat,there is renewed interest in the search for natural alternatives to the coccidiosis control *** study was conducted to test the anticoccidial efficacy of oregano and Citrus spp.-based essential oils for ***:A total of 2807-day-old broiler chicks were fed a control diet or diets with salinomycin or essential oils for up to 35 d of *** d 14,half of the control groups and the treated groups were orally challenged with a coccidiosis vaccine at 25 times higher than the recommended vaccine *** diet-fed chickens that were gavaged with phosphate-buffered saline were considered non-challenged control ***:Eimeria challenge or dietary additives failed to affect growth performance during the 7 to 20 d growth period although essential oil-fed chickens exhibited the lowest body wight gain(P=0.332)and the highest feed conversion ratio(P=0.062).Oocysts in the litter were detected in the challenged control diet group and the challenged/essential oil-fed groups at 21 and 35 d,*** dismutase activity in the serum was elevated(P=0.059)in the salinomycin-fed chickens compared to the challenged ***-1-acid glycoprotein was decreased by 28.7%in the salinomycin-fed chickens but increased by 38.1%in the essential oil group compared with the challenged control *** control group exhibited a significantly higher cooking loss of the thigh meat,compared to the non-challenged control diet group,which was marginally mitigated by dietary supplementation with essential *** fed essential oil-added diet had the highest branched-chain fatty acids contents in the ***:In conclusion,this study shows that oregano and Citrus-based essential oil preparation did not affect growth performance in broiler chickens challenged with the coccidiosis vaccine nor did Eimeria-spec
