Effect of bamboo vinegar powder as an antibiotic alternative on the digesta bacteria communities of finishing pigs

Abstract

This study investigated the use for bamboo vinegar powder as an antibiotic alternative in the diet of growing-finishing pigs by examining their digestive bacterial communities. Forty-five Duroc × Landrace × Yorkshire growing-finishing pigs were randomly allocated to five diet groups: 0%, 0.5%, 1.0%, or 1.5% bamboo vinegar levels and antibiotics. After 37 days, the digesta in duodenum of four pigs from each treatment were analyzed for their bacterial community compositions using 16S rRNA gene sequencing. The addition of 1.5% bamboo vinegar powder had an effect on the intestinal microflora most similar to that of antibiotics, indicating its potential to promote the growth and development of finishing pigs. We also found the 1.5% bamboo vinegar powder group to have an increased abundance of Firmicutes/Bacteroidetes compared with the other bamboo vinegar powder groups, which may enhance the ability of the host to absorb food energy and store more body fat. Additionally, the effects of bamboo vinegar powder on promoting the abundances of Lactobacillus and Thalassospira and on inhibiting Streptococcus and Prevotella growth revealed it may play an important role in animal production. Moreover, functional predictions of microbes via PICRUSt indicated that feed supplemented with 1.5% bamboo vinegar powder could promote many vital metabolic pathways.

Effects of Bamboo Vinegar on Production Performance, Egg Quality, Antioxidant Status, and Serum Biochemistry of Laying Hens in Summer

“…Reports found that feeding bamboo vinegar power increased GSH-PX and T-SOD activity. Moreover, BV in the diets of weaned pigs increased the activity of GSH-PX (Chu et al, 2013;Qu et al, 2018). In our study, the GSH-Px activity in serum was higher in laying hens fed BV at 30 days, which indicated that BV could effectively improve the antioxidant status of laying hens and eggs, which may contribute to the increase of albumin contents.…”

Pollution by Antibiotics and Antimicrobial Resistance in LiveStock and Poultry Manure in China, and Countermeasures

“…Controlling pathogens from the source, improving the health supervision system and biosafety route, and selecting some mature antibiotic substitutes (such as Chinese herbal medicine preparations, enzyme preparations, microbial preparations, etc.) can improve the economic benefits of agriculture [ 97 , 98 , 99 ].…”

Pharmacological Applications and Action Mechanisms of Phytochemicals as Alternatives to Antibiotics in Pig Production

“…Addition of 1.5% bamboo vinegar powder promotes the growth and development of growing-finishing pigs, increases the abundance of Firmicute / Bacteroidetes , enhances the ability of the host to absorb food energy and store more body fat in 37-days experiments. Additionally, bamboo vinegar powder has positive effects on promoting the abundance of Lactobacillus and Thalassospira and on inhibiting Streptococcus and Prevotella growth ( 98 ). 1% Wakame seaweed powder maybe alter intestinal microflora preferentially, namely, which are observed that an increase in Lactobacillus and a decrease of Escherichia coli to improve the gut health and immunity of pigs ( 99 ).…”
