This study investigated the effects of dietary supplementation with D1 ( D1) on growth performance, serum anti-inflammatory cytokines, and intestinal microbiota composition and diversity in bearded chickens. To investigate the effects of and fermented soy milk, 7-day-old broilers were orally fed different doses of D1 fermented soy milk for 35 days, with the unfermented soy milk group as the Placebo group. This study found that D1 fermented soy milk improved the intestinal microbiota of broilers, significantly increasing the abundance of beneficial bacteria and decreasing the abundance of harmful bacteria in the gut. D1 fermented soy milk also significantly reduced the serum lipopolysaccharide (LPS) content. The body weight and daily weight gain of broilers were increased. In conclusion, the results of this study are promising and indicate that supplementing the diets of bearded chickens with D1 fermented soy milk has many beneficial effects in terms of maintaining intestinal microbiota balance and reducing inflammation in chickens.
本研究调查了日粮添加D1对胡须鸡生长性能、血清抗炎细胞因子以及肠道微生物群组成和多样性的影响。为了研究D1和发酵豆浆的作用，给7日龄肉鸡口服不同剂量的D1发酵豆浆，持续35天，以未发酵豆浆组作为安慰剂组。本研究发现，D1发酵豆浆改善了肉鸡的肠道微生物群，显著增加了有益菌的丰度，降低了肠道有害菌的丰度。D1发酵豆浆还显著降低了血清脂多糖（LPS）含量。肉鸡的体重和日增重有所增加。总之，本研究结果很有前景，表明在胡须鸡日粮中添加D1发酵豆浆在维持鸡肠道微生物群平衡和减轻炎症方面有许多有益作用。
