Protein Sources For Horses (blog)

Discussion:

This table lists the variety of commercial protein sources available for horses. The ingredients often change so be sure to read the label for the most accurate ingredients. This list was updated December 2020 and I will not be updating it in the future (too much work).  I leave it up to you to investigate.

I still believe that feeding soybean meal alone is your best bet because:

  • it is a natural source of all the essential amino acids.
  • It is from the legume family like alfalfa, clover, birdsfoot trefoil, etc – all horses eat with few having bad reactions to.
  • It is used in ALL of the commercial feeds listed here as well as almost all other feeds
  • As an ingredient, it is the least expensive
  • As an ingredient, there are no added ingredients that inflame the gut

Other natural sources of protein are pea protein and hemp protein though they do not have the safety and efficacy track record of soybean meal in horses.

Notes and legend:

  • AA = Amino Acids from synthesis (man-made).
  • Anise seed – licorice flavoring has shown to be the favorite flavoring in trials with horses.
  • Bentonite – a clay used as a binder and absorbent to increase shelf life. Also used as a laxative when prescribed.
  • Betaine – derived from sugar beets it is an amino acid derivative.
  • CaCO3 – calcium carbonate – the calcium used in antacids such as “Tums.”
  • Choline chloride – is a growth stimulant used mostly in poultry feed.
  • Lignan sulfonate – an antioxidant in flame retardants and animal feed, derived from wood pulp production, the main ingredient in plaster, concrete, and sheetrock and used for dust control on dirt roads.
