Genome-Wide Association Study on Reproduction-Related Body-Shape Traits of Chinese Holstein Cows
Reproduction is an important production activity for dairy cows, and their reproductive performance can directly affect the level of farmers’ income. To better understand the genomic regions and biological pathways of reproduction-related traits of dairy cows, in the present study, three body shape...
