Compound probiotics have the characteristics of no drug resistance, residue, toxic effects, and no pollution. In order to investigate the capability of compound probiotics in piglets, a total of 16 healthy 30-day-old "Duroc × Yorkshire × Landrace" weaned piglets were randomly assigned into two groups: control group and compound probiotics (CP) group (2 mg • kg-1 basal diet compound probiotics). After 120 days, blood, liver tissues and muscle were sampled for detected the growth performance, serum biochemistry, liver hormones and related factors expression level of the JAK2/STAT5 signaling pathway. The results showed that the average daily gain was significantly increased, while the feed conversion rate (FCR) was remarkably decreased in the CP group (p<0.05). Moreover, the supplementation of compound probiotics could increase the contents of triglyceride (TG), glutamic-oxalacetic transaminase (AST), total cholesterol (TC), and glutamic-pyruvate transaminase (ALT) in serum, as well as the levels of growth hormone, insulin, thyroid-stimulating hormone and triiodothyronine.Meanwhile, the addition of compound probiotics upregulated the expression levels of GHR, JAK2, STAT3, STAT5a and STAT5b. In conclusion, compound probiotics promoted the growth performance of piglets by activating the JAK2/STAT5 signaling pathway.
