Chart displaying balance between horse nutrition requirements and your dietary supply.

Using this chart you can determine which feed amount should be adjusted.

The Based on Nutrient Requirements of Horses 6th Revision chart showing Dietary Supply series, Ideal 100% series.

Recommended sites: HorseChannel.com - Some Myths about horse diet	The program complements the information provided in the "Nutrient Requirements of Horses" by performing some of the procedures needed to calculate requirements. This program is not intended to replace the "Nutrient Requirements of Horses" book, which contains important information about the many factors that can influence the derivation and application of nutrient requirements to various situations. Knowledge of nutrient constraints and limitations of the suggested equations and models is essential for the proper use of this program in determining the nutrient requirements of specific horses. Because of the many variables involved and judgments that must be made in choosing inputs and interpreting outputs, the NRC and HorseMath.com make no claim for the accuracy of this software in predicting the requirements for individual horses in specific situations. The user is solely responsible for the risk of use. Careful review of the information presented in the "Nutrient Requirements of Horses" will assist users in making appropriate judgments in the use of this program.
