Bamboo is a fast-growing perennial plant that produces large amounts of biomass materials, thus having great potential to be used as a feedstock for a variety of areas such as food, as well as for livestock production. This experiment aimed to investigate the effects of fermented bamboo powder (FBP) on the growth performance, serum biochemical parameters, immunoglobulins and inflammatory cytokines, and fecal microbial composition of growing−finishing pigs. A total of 108 barrows (56.30 ± 0.55 kg) were randomly allocated to three dietary treatments in a 75-d trial, including a control diet and two FBP supplementation diets. The control diet was formulated to three-phase diets according to the body weight of pigs, and the FBP diets were formulated using 5.00% or 10.00% FBP to replace the wheat bran in the control diet, respectively. The performance parameters were measured throughout the experimental period and fecal and blood samples were collected on day 75.
The results showed that there were no influences on growth performances between the control diet and FBP addition diets, whereas the 5% FBP addition decreased the feed:gain of pigs compared to the pigs fed the 10% FBP diet from d 0−75. Meanwhile, the FBP addition increased the high-density lipoprotein cholesterol and immunoglobulin A content in serum and pigs fed the 5% FBP diet had greater high-density lipoprotein cholesterol and immunoglobulin A contents in serum than those in the pigs fed the control diet. Microbial analysis showed that the FBP addition diets decreased the abundance of Spirochaetes, and the 10% FBP diet increased the abundance of Firmicutes more than the control diet. In addition, the pigs fed the 10% FBP diet increased the abundance of uncultured_bacterium_f_Lachnospiraceae, Ruminococcaceae_UCG-005, Prevotellaceae_UCG-003, Lachnospiraceae_XPB1014_group, and Lactobacillus more than the control group.
In conclusion, 5% of FBP supplementation in growing finishing diets may exert a beneficial effect on serum biochemical and immune indices, as well as modulate the fecal microbiota.
