Fig 4. Effect of weaning on intestinal lactate concentration and lactobacilli load of piglets.

(A) Lactate concentration (B) Lactobacillus load and (C) pH in chyme of suckling and weaned piglets along the intestinal axis was measured. Statistical analysis was performed with the procedure “MIXED” (SAS, version 8) and comparison between pre- and postweaning using the t-test (p<0.01).
