Abstract

Probiotics have received attention as alternatives to antibiotics due to their relative biosafety. Despite the health-promoting effects of multispecies probiotic formulation (MPF) in weaning pigs were well-documented, the health-promoting potential of MPF in growing-finishing pigs remain limited. Therefore, we conducted a six-week experiment to investigate the beneficial effects of MPF supplementation (the formulations containing Lactobacillus plantarum CJLP243, L. fermentum LF21, L. salivarius E4101, Leuconostoc paramesenteroides KJP421, Bacillus subtilis CJMPB957 and B. licheniformis CJMPB283) on intestinal environments and hepatic lipid metabolism in growing-finishing pigs. The results showed that the growth performance of MPF group was improved compared to control group during the experimental period without affecting feed intake. The dietary MPF supplementation also significantly increased the jejunal mRNA expression levels of zonula occludens-1 (ZO-1) and decreased that of interleukin-12 (IL-12). Dietary MPF supplementation was found to not only reduce the hepatic triglyceride concentration but down-regulate hepatic mRNA expression levels of lipid metabolism-related markers, such as as sterol regulatory element-binding transcription factor 1c (SREBP-1c), CCAAT/enhancer binding protein α (CEBPα), acetyl coA carboxylase (ACC) and carnitine palmitoyl transferase 1β (CPT1β). Nonetheless, MPF supplementation also had the capability to modulate gut microbiota populations, including Clostridiaceae, Lachnospiraceae, and Turicibacter. Collectively, our results suggest that dietary MPF inclusion could be a promising approach to promote the growth performance and the overall health of growing-finishing pigs via modulation of gut microbiota.
