We examined the effects of encapsulated lactic acid bacteria administrated orally to lactating cattle on the intestinal flora. A dose of 3 × 1011 colony forming unit (cfu) of freeze-dried Lactobacillus coryniformis subsp. torquens (JCM1099) encapsulated in an enteric capsule capable of bypassing the rumen was administered for seven days. DNA was extracted from feces 0 and 24 hr after daily administration. Metagenomic analysis showed an increasing trend of the alpha diversity, an index of the species diversity. Furthermore, principal component analysis of intestinal flora revealed that cattle could be differentiated by JCM1099 capsule and suspension administration via principal components 1, 2, and 3. We conclude that administration of encapsulated JCM1099 can alter the intestinal bacterial flora of cattle.
