摘要

Improving growth performance is vital in poultry production. Although several studies have established associations between gut microbiota and growth, the direct impacts remain unclear. A total of 120 1-day-old Sansui ducks were randomly assigned to the FMT and CON groups. From the 1st day, ducks in the FMT group were orally administrated with 0.5 mL fecal microbiota suspension for three consecutive days, while sterile PBS solution was used as a substitute in the CON group. The results revealed that FMT improved average daily gain (ADG) (P < 0.001) and body weight (BW) (P < 0.001), with a tendency for a better feed conversion rate (FCR) (P = 0.062). LEfSe analysis indicated a significant increase in the abundance of the Lactobacillus (P < 0.001), Bifidobacterium (P = 0.006), Megamonas (P = 0.008), and Subdoligranulum (P = 0.005) in the FMT group. Similarly, the phyla Firmicutes/Bacteroidetes ratio was higher in the FMT group compared to the CON group. Additionally, the ACE, Chao, and Shannon indices were also significantly higher in the FMT group (P < 0.001). To sum up, FMT enhanced growth performance, which could be associated with reducing proinflammatory pathogen colonization in the duck cecum. This modulating effect likely results from increased microbial diversity and the enrichment of beneficial bacteria.
