  2. The effect of interval between inseminations and semen handling on in-vivo and in-vitro fertility of frozen-thawed boar sperm

    Ringwelski, JenniferUniversity of Illinois at Urbana-Champaign2014

    … yet been able to capitalize on the potential of frozen-thawed boar sperm (FTS), due to the biological sensitivity of the sperm cells and the lower resulting pregnancy rates and litter sizes. This thesis will outline the current swine reproductive production practices, provide a brief history of …

  4. Enhanced fertility estimation and novel ion channels in boar sperm

    Daigneault, Bradford W.University of Illinois at Urbana-Champaign2015

    Cryopreserved boar sperm have many potential advantages when used for artificial insemination (AI), including increased time for pathogen testing and ease of semen transport. However, frozen boar sperm are seldom used for AI due to decreased pregnancy rates and litter sizes as a result of …

  5. Factors affecting fertility in frozen-thawed boar sperm

    Spencer, Karl W.University of Illinois at Urbana-Champaign2010

    Frozen-thawed boar sperm holds the potential to have an impact on the future of the swine industry. Utilization of this technology could improve a swine producer’s ability to access top-tier genetics from around the world, to improve efficiency, profitability, and the quality of product to meet …
