Study Name: Understanding the Biology of Seasonal Infertility to Develop Mitigation Strategies

Summary: Seasonal infertility accounts for an estimated $1 billion in annual revenue losses to the swine industry. Heat stress is a predicable event (particularly seasonal infertility) for which mitigation strategies are dramatically lacking.

Key Points:

  • Seasonal infertility in commercial pork production systems was not strongly correlated with heat stress during the wean–to–estrus interval.
  • However, heat stress during other production phases, such as late gestation and/or lactation could influence reproductive ability.
