Effect Of Cnv Of Production Related Genes On Expression Of Production Traits In Dairy Cattle, Tyler Kamper

Dairy Science

The objective of this project was to determine if copy number variation (CNV) at specific genes related to BST had an effect on milk production. Hair samples from 1000 fresh heifers from Maddox Dairy in Riverdale, CA were sent to Geneseek, a Neogen Company for DNA extraction and processing. The DNA was processed using the BovineSNP50 BeadChip and the data were loaded into the GenomeStudio software. The data were manipulated in GenomeStudio to estimate the CNV at each single nucleotide polymorphism (SNP) of which a vast majority was two. The SNPs with a copy number of two were excluded and …
