Supplementation of the probiotic <i>Lactobacillus rhamnosus</i> GG to pre-weaning calves decreases diarrhea incidence by modulating gut bacteria and associated metabolites.

ABSTRACT: The aim of the present study was to investigate whether Lactobacillus rhamnosus GG (LGG) could be utilized as an effective strategy to promote growth performance of calves and to further study its impact on decreasing diarrhea. A total of 18 healthy Holstein calves (age 8 ± 3 days, weight 42.48 ± 1.04 kg) were raised in a centralized manner to minimize differences and then divided into two groups: one group received LGG supplementation (1 × 10¹⁰ CFU per calf per day), while the other served as the control (CON). Each group consisted of 9 replicates, with 1 calf per replicate. The experimental period spanned 6 weeks. The experimental results demonstrated an increase of the average daily growth (P = 0.094) and a highly significant reduction in diarrhea (P = 0.
