Cecal and colinic 16s rRNA sequencing OTUs

The purpose of this study was to investigate the effects of Fermented Spent Mushroom Substrates (FSMS) on growth performance, serum biochemical, gut digestive enzyme activity, microbial community, genes expression of tight junction proteins and volatile fatty acids (VFA) in hindgut (colon and cecum) of weaned piglets. A total of 100 weaned Yihao native pigs (Native × Duroc, 50 males and 50 females) were allocated to two groups with five replicates and ten pigs per replicate. Pigs in the control group were fed a basal diet (BD group) and the others were fed basal diets supplemented with 3% FSMS (FSMS group). Relative to the BD Group, it had better results for Final weight, average daily gain (ADG) and feed conversion ratio (FCR) in FSMS Group but not significant (p > 0.05) which was accompanied by improved serum T3, IgG and IgA (p < 0.05) but lower serum TP, ALB, TC and TG during the overall period (p < 0.05). Similarly, FSMS significantly up-regulated (p < 0.05) the expressi...

本研究旨在探究发酵菌糠（Fermented Spent Mushroom Substrates，FSMS）对断奶仔猪生长性能、血清生化指标、肠道消化酶活性、微生物群落、紧密连接蛋白基因表达以及后肠（结肠与盲肠）挥发性脂肪酸（volatile fatty acids，VFA）的影响。试验共选取100头断奶壹号本地猪（本地猪×杜洛克猪，公母各50头），随机分为2组，设置5个重复，每个重复10头猪。对照组仔猪饲喂基础日粮（BD组），其余组饲喂添加3% FSMS的基础日粮（FSMS组）。相较于BD组，FSMS组的末重、平均日增重（average daily gain，ADG）及饲料转化率（feed conversion ratio，FCR）均表现更优，但差异未达显著水平（p > 0.05）；试验全周期内，该组血清三碘甲状腺原氨酸（triiodothyronine，T3）、免疫球蛋白G（Immunoglobulin G，IgG）与免疫球蛋白A（Immunoglobulin A，IgA）水平显著提升（p < 0.05），但血清总蛋白（Total Protein，TP）、白蛋白（Albumin，ALB）、总胆固醇（Total Cholesterol，TC）及甘油三酯（Triglyceride，TG）水平显著降低（p < 0.05）。类似地，FSMS可显著上调（p < 0.05）[原文内容截断]
