Effects of two strains of Lactobacillus isolated from the feces of calves after fecal microbiota transplantation on growth performance, immune capacity, and intestinal barrier function of weaned calves.

ABSTRACT:

Introduction

Weaning stress seriously affects the welfare of calves and causes huge economic losses to the cattle breeding industry. Probiotics play an important role in improving animal growth performance, enhancing immune function, and improving gut microbiota. The newly isolated strains of Lactobacillus reuteri L81 and Lactobacillus johnsonii L29 have shown potential as probiotics. Here, we studied the probiotic properties of these two strains on weaned calves.

Methods

Forty calves were randomly assigned to four groups before weaning, with 10 calves in each group, control group (Ctrl group), L. reuteri L81 supplementation group (2 g per day per calf), L. johnsonii L29 supplementation group (2 g per day per calf), L. reuteri L81 and L.
