SUMMARY Supplementing broiler diets with medicinal mushrooms is considered an effective alternative to prophylactic antibiotics. Feeding certain mushrooms may have beneficial effects on gut health in broilers, whereby trials have shown weight gain was increased about 5.2% when feeding 5% of the Hericium caput-medusae mushrooms in the diet. Both Salmonella spp. and E. coli numbers in the caecum were significantly lowered from 5.036 to 3.031 log10 CFU/g and from 5.405 to 4.759 log10 CFU/g when 50 g/kg or 30 g/kg of Flammulina velutipes mushrooms were included in feed, respectively, compared to an unsupplemented control group. Beneficial bacteria (Lactobacilli spp.) were found in significantly higher numbers (increased from 6.45 to 8.05 log10 CFU/g) and Bifidobacter spp. (increased from 6.28 to 7.77 log10 CFU/g of content) in the caecum of broilers fed 20 g/kg mushrooms (Agaricus biosporus) in feed. However, there is still disagreement in published articles on the dosages and mode of action of medicinal mushrooms in broilers. The following review covered the published trials investigating the uses of medicinal fungi on growth performance, meat quality and health status in broiler to date, and showed that supplementation with medicinal fungi may have a role on the immunity, health and growth performance in broiler.

药用蘑菇对肉鸡生长性能和生理反应的影响

总结 用药用蘑菇补充肉鸡日粮被认为是预防性抗生素的有效替代品。饲喂某些蘑菇可能对肉鸡的肠道健康有益，试验表明，在日粮中饲喂 5% 的猴头菇时，体重增加约 5.2%。两种沙门氏菌属。与饲料中分别添加 50 g/kg 或 30 g/kg 金针菇时，盲肠中的大肠杆菌数量分别从 5.036 至 3.031 log10 CFU/g 和 5.405 至 4.759 log10 CFU/g 显着降低到未补充的对照组。有益细菌（乳酸杆菌属）的数量显着增加（从 6.45 增加到 8.05 log10 CFU/g）和双歧杆菌属。（从 6.28 增加到 7。77 log10 CFU/g 含量）在饲料中添加 20 g/kg 蘑菇（Agaricus biosporus）的肉鸡的盲肠中。然而，关于药用蘑菇在肉鸡中的剂量和作用方式，发表的文章仍然存在分歧。以下综述涵盖了迄今为止已发表的关于药用真菌对肉鸡生长性能、肉质和健康状况的研究，并表明添加药用真菌可能对肉鸡的免疫、健康和生长性能产生影响。
