    Summary

    Prostaglandin F(2alpha) effectively induced farrowing in sows when administered on day 111-113 of gestation. This method offers practical benefits for swine production units without negatively impacting piglet or sow performance.

    Area of Science:

    • Veterinary Medicine
    • Animal Science
    • Reproductive Biology

    Background:

    • Efficient management of parturition in swine is crucial for optimizing reproductive performance.
    • Induction of farrowing can facilitate better supervision and resource allocation in farrowing units.

    Purpose of the Study:

    • To evaluate the efficacy of prostaglandin F(2alpha) for inducing parturition in pregnant swine.
    • To assess the impact of induced farrowing on key reproductive and production parameters.

    Main Methods:

    • Intramuscular administration of prostaglandin F(2alpha) (5-12.5 mg) to 116 pregnant swine on days 111-113 of gestation.
    • Monitoring farrowing times, litter characteristics, piglet growth, and subsequent rebreeding performance.

    Main Results:

    • Sixty-three percent of treated sows farrowed during the working day post-treatment.
    • Parturition time, birth weight, litter size, and piglet weaning success were comparable to expected herd performance.
    • Subsequent rebreeding of dams was not adversely affected by the treatment.

    Conclusions:

    • Prostaglandin F(2alpha) is an effective agent for inducing parturition in swine.
    • This technique can be practically applied in intensive swine production to improve farrowing unit efficiency.
    • Controlled induction of farrowing offers benefits for management and resource optimization.
