High feed intake for sows after farrowing boosts piglet growth and milk yield. Restricted feeding initially, then ad libitum, supports sow health and performance during lactation.

Area of Science:

  • Animal Science
  • Reproductive Biology
  • Nutritional Physiology

Context:

  • Sow nutrition and milk production are critical for piglet survival and growth.
  • Lactation performance in sows is influenced by pre-farrowing and post-farrowing feeding strategies.
  • Understanding energy requirements during lactation is essential for optimizing sow and piglet outcomes.

Purpose:

  • To evaluate the impact of varying pre-farrowing feed amounts on sow N-balance and milk yield.
  • To determine the relationship between sow energy intake post-farrowing and piglet performance.
  • To assess the efficacy of peripartal additives on sow health and lactation performance.

Summary:

  • Continuous nitrogen (N)-balances were measured in sows over 14 days, with milk yield estimated via piglet daily gain.

Related Experiment Videos

  • Sows were fed varying amounts pre-farrowing, with ad libitum feeding during trials; milk yield decreased after the first week.
  • Higher post-farrowing energy intake correlated with better piglet performance; 65 antibiotic treatments were administered for fevers (>39.5°C).

    • Impact:

    • Recommends high post-farrowing feeding for sows, tailored to needs, with restricted and increasing amounts in the first lactation week.
    • Suggests peripartal additives like antibiotics or acids can benefit sow health and overall performance.
    • Provides insights into optimizing sow feeding strategies to enhance milk production and piglet growth.
