The Relation of Ascorbic Acid to Breeding Performance in Horses1

George K. Davis and C. L. Cole

Michigan Agricultural Experiment Station2

Abstract

  1. Blood ascorbic acid values for good breeders, in mares of both heavy and light breeds, were significantly higher than those of poor breeders.
  2. Good breeding Belgian and Percheron mares had an average value of 0.15 mg. per cent of plasma as against 0.07 mg. per cent for difficult breeders.
  3. Corresponding values for light horse breeds were 0.129 and 0.09 mg. per cent of blood plasma.
  4. Individuals differ widely in blood ascorbic acid value.
  5. Results with one stallion indicate a possible role of ascorbic acid in the production of motile sperm.
  6. Mares going on pasture show a rise in blood ascorbic acid values.
