    Summary

    Sow reproductive health shows significant blood parameter changes during estrus. Key indicators like 11-hydroxycorticosteroids, iron, and hemoglobin increase, while inorganic phosphorus and vitamin A decrease.

    Area of Science:

    • Veterinary Medicine
    • Animal Physiology
    • Reproductive Biology

    Context:

    • Estrous cycle monitoring in sows is crucial for reproductive success.
    • Understanding physiological changes during estrus aids in optimizing breeding management.
    • Previous research has identified behavioral estrus indicators, but comprehensive blood parameter analysis is less explored.

    Purpose:

    • To investigate and quantify changes in various blood parameters in clinically healthy sows during the estrous cycle.
    • To compare blood serum and whole blood levels of seventeen parameters before, during, and after estrus and insemination.
    • To identify specific biomarkers associated with the estrus period in sows.

    Summary:

    • Ten healthy sows were monitored across three phases: pre-estrus, estrus, and post-insemination.
    • Blood samples were analyzed for seventeen parameters, including 11-hydroxycorticosteroids, iron, alanine aminotransferase, aspartate aminotransferase, hemoglobin, inorganic phosphorus, and vitamin A.
    • Estrus was associated with increased 11-hydroxycorticosteroids, iron, alanine aminotransferase, and hemoglobin. A decrease in inorganic phosphorus and vitamin A was also noted during estrus.

    Impact:

    • Provides a detailed physiological profile of sows during estrus, aiding in estrus detection and reproductive health assessment.
    • Identifies specific blood parameters that can serve as objective indicators of estrus in swine.
    • Contributes to improved reproductive efficiency and herd management strategies in swine production.
