Abstract

This study was designed to investigate the effects of fermented feed diets on the growth performance and cecal microbial community in geese, and to examine associations between the gut microbiota and growth performance. A total of 720 healthy, 1-day-old male SanHua geese were used for the 55-D experiment. Geese were randomly divided into 4 groups, each with 6 replicates of 30 geese. Groups were fed a basal diet supplemented with 0.0, 2.5, 5.0, or 7.5% fermented feed. The results showed that 7.5% fermented feed had an increasing trend in the body weight and average daily gain of the geese; however, there was no significant response to increasing dietary fermented feed level with regards to ADFI and FCR. In addition, compared with the control group, there was a higher abundance of bacteria in the phylum Bacteroidetes in the cecal samples of geese in the 7.5% fermented feed group (53.18% vs. 41.77%, P0.05), whereas the abundance of Firmicutes was lower in the 7.5% fermented feed group (36.30% vs. 44.13%, P0.05). At the genus level, the abundance of Bacteroides was increased by adding fermented feed to geese diets, whereas the abundances of Desulfovibrio, Phascolarctobacterium, Lachnospiraceae_uncultured, Ruminiclostridium, and Oscillospira were decreased. These results indicate that fermented feeds have an important effect on the cecal microflora composition of geese, and may affect host growth, nutritional status, and intestinal health.
