The gut microbiota plays important roles in animal overall health and productiveness. Balancing host gut microbiota by probiotics has been documented. Our previous study showed that Saccharomyces boulardii(Sb) and Bacillus subtilis B10(Bs) significantly improve growth performance and modulate the intestinal histomorphology in broilers. To increase the knowledge regarding Sb and Bs, this study investigated the effects of these 2 probiotic strains on the gut microbiota in broilers. Three hundred 1-day-old Sanhuang broilers(Chinese cross breed) were randomly divided into 3 groups, each group with 5 replications(n = 20). The control group(CK) was fed a basal diet containing an antibiotic(virginiamycin, 20 mg/kg) and the other 2 groups received Sb and Bs(1 × 10~8cfu/kg of feed) in addition to the basal diet. After 72 d of treatment, pyrosequencing revealed that the bacterial communities varied along the section of intestinal tract in the control and Bs groups, but not in the Sb group. No difference in microbial diversity was observed among 3 groups. The major phyla observed along the GI tract of broilers(particularly in the duodenum and cecum) were Firmicutes, Bacteroidetes, Proteobacteria, and Verrucomicrobia, which were considered potentially growth performance-related. Bacteroidetes, Proteobacteria, and Verrucomicrobia were observed at a much higher abundance in the jejunums and ileums of the Sb group(P lism among the groups, based on the principal component analyses. These data indicated that Sb and Bs can modulate the microbial ecosystem, and subsequently enhance the health status of broilers.

Background:This study aimed to investigate whether the combination of Macleaya cordata extract(MCE)and Bacil-lus could improve the laying performance and health of laying hens ***:A total of 36029-week-old Jingbai laying hens were randomly divided into 4 treatments:control group(basal diet),MCE group(basal diet+MCE),Probiotics Bacillus Compound(PBC)group(basal diet+compound Bacil-lus),MCE+PBC group(basal diet+MCE+compound Bacillus).The feeding experiment lasted for 42 ***:The results showed that the laying rate and the average daily egg mass in the MCE+PBC group were significantly higher than those in the control group(Plicle-stimulating hormone(FSH)in the serum and up-regulated the expression of related hormone receptor gene(estrogen receptor-β,FSHR and luteinizing hormone/choriogonadotropin receptor)in the ovary of laying hens(Plial barrier detected by transmission electron microscopy was enhanced compared with the control group(P<0.05).In addition,compared with the control group,combination of MCE and Bacillus significantly increased the total antioxidant capacity and catalase activity(P<0.05),and down-regulated the mRNA expressions of inflammation-related genes(interleukin-1βand tumor necrosis factor-α)as well as apoptosis-related genes(Caspase 3,Caspase 8 and P53)(P<0.05).The concen-tration of acetic acid and butyric acid in the cecum content of laying hens in the MCE+PBC group was significantly increased compared with the control group(P<0.05).Conclusions:Collectively,dietary supplementation of 600μg/kg MCE and 5×108 CFU/kg compound Bacillus can improve laying performance by improving microbiota to enhance antioxidant capacity and intestinal barrier,regulate reproductive hormones and the
