Background: Avian coccidiosis is considered among the infectious disease of high cost in the poultry industry. Herbal extracts are safe and reliable substitute anticoccidial drugs for chemical feed additives as they do not sequel to drug resistance and tissue remnants.
Objective: The current study aimed to assess the anticoccidial effect of an herbal complex of 3 plants (, , and ) in broiler chickens compared to toltrazuril anticoccidial.
Methods: This experiment used one hundred twenty broiler chickens and divided them into four equally numbered groups. All the groups, except group (D), were experimentally infected with mixed spp. (. , , and ) on day 14. Group (A) was treated with a herbal mixture, containing 75% with a minimum of 30% total tannin, 16% with a minimum of 0.02% artemisinin, and 9% with a minimum of 0.4% total phenol contents. Group (B) was treated with toltrazuril. Group (C) did not have any treatment. Group (D) was healthy all the experiment period as a negative control group. During a 42-day breeding period, the study examined clinical signs, weight gains, feed conversion ratio, lesions scoring, casualties, and the number of oocysts in different bird groups.
Results: Group (D) showed the most significant weight gain, indicating the economic damage caused by coccidiosis. The best feed conversion ratio was observed in the unchallenged group, and coccidiosis negatively affected it in other groups. Clinical signs of dysentery, diarrhea, and lethargy were seen post-challenge but improved with treatment. Group (D) showed no losses; others had casualties and coccidiosis lesions. Lesion scores were lowest in the group (D), and the herbal mixture improved performance. The herbal mixture and toltrazuril reduced oocyst counts in feces earlier than the untreated group.
Conclusion: In conclusion, the anticoccidial activity of the mentioned herbal complex recommends its use as an alternative anticoccidial agent to chemotherapeutic drugs for controlling coccidiosis.
