Horses undergoing extensive colon resection (up to 95%) can maintain health with alfalfa hay and ample water. This diet supports nutrient balance and body weight despite reduced digestive capacity.

Area of Science:

  • Veterinary Surgery
  • Equine Internal Medicine
  • Gastrointestinal Physiology

Background:

  • Large colon resection and anastomosis are performed in horses.
  • Surgical techniques vary based on lesion location and extent.
  • Extensive resections can lead to long-term physiological deficits.

Purpose of the Study:

  • To evaluate the long-term effects of extensive large colon resection on horses.
  • To determine optimal dietary management strategies post-resection.
  • To assess the impact on water absorption, nutrient digestion, and overall health.

Main Methods:

  • Review of surgical outcomes for large colon resection and anastomosis.
  • Analysis of physiological consequences in horses with extensive resections (up to 95%).

  • Comparative feeding trials using alfalfa hay versus grass hay.

    • Main Results:

    • Extensive colon resection (95%) results in permanent deficits in water absorption and cellulose/protein digestion.
    • Reduced fermentative capacity is observed due to decreased retention time.
    • Alfalfa hay (2% body weight) supports normal blood variables and body weight.
    • Grass hay is inadequate as a sole forage source, leading to weight loss.
    • Increased voluntary water intake is crucial.

    Conclusions:

    • Horses with extensive colon resection require specific dietary management for long-term health.
    • Alfalfa hay is a suitable forage to mitigate nutritional deficits.
    • Adequate water intake is essential to compensate for increased fecal water loss.
