Nutrient Requirement Tables
Nutrient requirements are based on mature body weights. Click on the mature body weight or breed of your horse to bring up the appropriate table.
Mature Body Weights
|Lbs. / Kg.||441 / 200||661 / 300||882 / 400||1102 / 500||1323 / 600||1543 / 700||1764 / 800||1984 / 900|
The nutrient requirement tables are from the National Research Council (NRC) 1989 Nutrient Requirements for Horses. The requirements are based on the latest documented research. All of the requirement values in the tables are the total amount of each nutrient required per day. For example, an 1102 lb. horse at maintenance requires 656 grams of crude protein (CP), 23 grams of lysine (Lys), 20 grams of calcium (Ca), etc.. Your analysis report provides results in grams/pound or grams/kilogram so that you can calculate the nutrient contribution from the analyzed feed.
