Electronic Theses and Dissertations

The gut development of young calves is crucial for the producer and the calf's future. Many factors can affect the development of a young calf's gastrointestinal system, and there has been little research into the fecal microbiome development of calves from 0 to 12 weeks of age. To gain further insight into this process, development of the fecal microbiome in 12 dairy calves was investigated. Fecal bacterial composition was determined at four time points (weeks 0, 4, 8 and 12) using the 16S rRNA gene through PCR-amplification of the V1-V3 regions from fecal microbial genomic DNA, followed by Illumina MiSeq …
