What influences semen quality? – presentation by Dr. Tom Lewis

Taking a look at the temporal trends in a number of semen traits. Genetic analysis of these traits and determination of heritability.

Tom is a quantitative geneticist and has spent over a decade in research focusing on the genetic analysis of complex inherited disease and population structure in pedigree dog breeds. With a background in animal science, he gained his PhD investigating multiple aspects of quantitative genetics at the Roslin Institute and Nottingham University. Since then, Tom has worked at the Animal Health Trust and the Kennel Club, using pedigree and health testing data as the basis of his research, including the provision of estimated breeding values (estimates of genetic risk of hip and elbow disease), for multiple Kennel Club registered breeds. He joined Guide Dogs as Head of Canine Genetics in January 2021.
