on indigenous
lactobacilli in the pig cecum and found that continuous consumption of this strain will stimulate the
growth of some indigenous lactobacilli and alter the composition of the lactobacilli. L. plantarum
ZJ316 (the control group was fed a diet supplemented with the antibiotic mequindox, three groups with
different L. plantarum levels and a group with a mixture of mequindox and L. plantarum) was also
found to improve pig growth and pork quality. The probiotic mechanism was related to the inhibition
of the growth of opportunistic pathogens and promotion of increased villus height [30].
