摘要
This study aimed to investigate the effects of dietary supplementation with fermented soybean meal (FSM) or fermented miscellaneous meal (FMM, cottonseed meal: coconut meal = at a 1:1 ratio) on the intestinal health, laying performance, egg quality, and follicle development of laying hens. A total of 1,008 54-wk-old laying hens were randomly divided into 7 treatment groups and fed a corn-soybean base diet in addition to 2%, 4%, and 8% FSM or FMM. The results showed that fermentation increased the contents of crude protein, amino acids (Ser, Gly, Cys, Leu, Lys, His, and Arg), and organic acids (butyric acid, citric acid, succinic acid) and decreased the contents of neutral and acid detergent fiber in the soybean and miscellaneous meals (P ADFI), and feeding with 4% FMM increased the ADFI of laying hens (P P P P DAO) activity, transepithelial electrical resistance (TEER), and the expression of tight junction proteins (ZO-1, Occluding, and Claudin1), the intestinal stem cell marker Lgr5, and the proliferation cell marker proliferating cell nuclear antigen (PCNA) was upregulated in the jejunum of laying hens fed 4% FSM and FMM (P P

这项研究旨在研究用发酵大豆粉（FSM）或发酵的其他餐（FMM，棉籽粉：椰子粉=以1：1的比例）对饮食补充的影响对肠道健康，铺设性能，卵子质量和卵泡质量和卵泡的影响生育母鸡的发展。总共将1,008个54周龄的母鸡随机分为7个治疗组，除了2％，4％和8％的FSM或FMM外，还喂了玉米大豆碱饮食。结果表明，发酵增加了粗蛋白，氨基酸（Ser，Gly，Cys，Leu，Lys，His和arg）和有机酸（丁酸，柠檬酸，琥珀酸）的含量，并减少了中性的含量。大豆和其他餐（P ADFI）中的酸性纤维和4％FMM的喂养增加了母鸡的ADFI（p p p do）活性，旋转型电阻（TEER），以及紧密连接蛋白的表达（ZO----1，阻塞和claudin1），肠干细胞标记LGR5以及增殖细胞标记物增殖细胞核抗原（PCNA）在饲喂4％FSM和FMM的饲养母鸡的空肠中上调（P P PM）
