GENOMIC ANALYSIS OF SOW REPRODUCTIVE TRAITS: IDENTIFICATION OF SELECTIVE SWEEPS, MAJOR GENES, AND GENOTYPE BY DIET INTERACTIONS By Melanie Dawn Trenhaile A THESIS Presented to the Faculty of The Graduate College at the University of Nebraska In Partial Fulfillment of Requirements For the Degree of Master of Science Major: Animal Science Under the Supervision of Professor Daniel Ciobanu Lincoln, Nebraska December, 2015 GENOMIC ANALYSIS OF SOW REPRODUCTIVE TRAITS: IDENTIFICATION OF SELECTIVE SWEEPS, MAJOR GENES, AND GENOTYPE BY DIET INTERACTIONS Melanie D. Trenhaile, M.S. University of Nebraska, 2015 Advisor: Daniel Ciobanu Reproductive traits, such as litter size and reproductive longevity, are economically important. However, selection for these traits is difficult due to low heritability, polygenic nature, sex-limited expression, and expression late in life.
