We studied the compositional changes in the intestinal microbiome of newborn calves during the first week after birth by metagenomic analysis. In feces from newborn calves, we identified 4 bacterial phyla, namely, Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. The relative abundance of Lactobacillaceae significantly increased from day 1 to day 7. We evaluated Lactobacillus spp. colony numbers using selective agar plates and confirmed that the abundance of Lactobacillus spp. significantly increased during the first 7 days after birth. In conclusion, Lactobacillus spp. colonized the intestinal tract of calves during the first 7 days after birth.}, pages = {452--455}, title = {Postnatal changes in the relative abundance of intestinal Lactobacillus spp. in newborn calves}, volume = {79}, year = {2017} }
