Abstract：
(1) Background: Various studies on artemisinin and its derivatives have shown that Artemisia annua may be of therapeutic interest for different diseases, including chicken coccidiosis. This study aimed to evaluate the effects of Artemisia annua on farm-reared broiler chickens by analyzing both the anticoccidial efficacy and its effect on the intestinal microbiota of poultry. (2) Methods: The experiment was performed within three houses on a broiler chicken farm located in Romania. House 1 was the experimental group and received a diet with an addition of A. annua. Houses 2 and 4 were the control groups and received anticoccidials. The prophylactic efficacy of A. annua against coccidiosis was evaluated by recording the weight gain, feed conversion rate, number of oocysts per gram of feces, lesion score, and mortality rate. (3) Results: The chickens fed with A. annua showed a decreasing trend in the number of oocysts per gram of faeces, and their lesion score was 80% lower than in the control group. The weight gains of the chickens treated with A. annua was lower, whilst the feed conversion rate was better than in controls. (4) Conclusions: Artemisia annua showed promising results in the prophylaxis of coccidiosis. Overall, the broiler chickens that received A. annua presented promising zootechnical performances and medical data related to coccidiosis and gut microbiota.
摘要：
（1）背景：对青蒿素及其衍生物的各种研究表明，黄花蒿可能对不同的疾病具有治疗意义，包括鸡球虫病.本研究旨在通过分析黄花蒿的抗球虫功效及其对家禽肠道菌群的影响来评估黄花蒿对农场饲养肉鸡的影响。(2)方法:实验在位于罗马尼亚的肉鸡养殖场的三个房屋内进行。房子1是实验组，并接受了添加A.annua的饮食。房屋2和4是对照组，并接受了抗球虫药。通过记录体重增加来评估黄花菊对球虫病的预防功效，饲料转化率，每克粪便的卵囊数量，病变评分,和死亡率。(3)结果:饲喂黄花鸡每克粪便卵囊数呈下降趋势,病变评分比对照组低80%。用黄花A处理的鸡的体重增加较低，而饲料转化率优于对照。（4）结论：蒿在预防球虫病方面显示出可喜的结果。总的来说,收到A.annua的肉鸡提供了有希望的动物技术性能和与球虫病和肠道微生物群相关的医学数据。
