Abstract

Abstract: This study aimed to investigate the effects of fermented bamboo powder on growth performance, apparent nutrient digestibility, serum biochemical indices and fecal microbiota of finishing pigs. A total of 144 healthy “Duroc × Landrace × Yorkshire” cross‑bred finishing pigs with similar age and body weight were randomly assigned to three treatment groups, with six replicates per group and eight pigs per replicate. Pigs in the control group were fed a basal diet, while the two experimental groups were fed basal diets supplemented with 3% and 5% fermented bamboo powder, designated as CON, FBP3 and FBP5 groups, respectively. Compared with the CON group, final body weight was significantly decreased in FBP3 and FBP5 groups (P＜0.05), and average daily gain was significantly lower in the FBP5 group (P＜0.05). The average daily feed intake (ADFI) in the FBP3 and FBP5 groups was lower than that in the CON group. The ADFI of the FBP5 group was lower than that of the FBP3 group, but the differences were not significant (P＞0.05). The apparent digestibility of dry matter, crude protein, ether extract, ash and gross energy in FBP3 and FBP5 groups was significantly higher than that in the CON group (P＜0.05). For serum parameters, serum glucose concentration was significantly reduced while serum triglyceride concentration was significantly elevated in the FBP5 group (P＜0.05). Meanwhile, the FBP3 group exhibited significantly higher serum malondialdehyde content and significantly lower total antioxidant capacity (P＜0.05). In terms of fecal microbiota, Shannon index was significantly increased and the Simpson index was significantly decreased in FBP3 and FBP5 groups (P＜0.05). The relative abundance of Streptococcus was significantly reduced in the FBP5 group, whereas the relative abundances of Clostridium and Terrisporobacter were significantly increased in both FBP3 and FBP5 groups (P＜0.05). Fermented bamboo powder can improve intestinal health and promote nutrient digestion and utilization of finishing pigs by regulating intestinal microecology. Considering that the high fiber content and low nutritional concentration of fermented bamboo powder may reduce feed intake and further impair the growth rate of finishing pigs, the supplemental level of fermented bamboo powder in finishing pig diets should not exceed 3%.

Key words: fermented bamboo powder, finishing pigs, growth performance, nutrient digestibility, fecal microbiota
