Protein and Nonprotein Nitrogen Utilization in the Horse1

Abstract

The recommended nutrient allowances for horses (N.R.C., 1966) are derived, in many cases, from experimental results obtained with cattle. Word and Breuer (1967) concluded the published values for the digestible protein and energy contents of feeds derived with ruminants could be used to formulate the type of horse rations used in their study. However, Ensminger (1966) suggested the nutritive requirements of the horse more nearly parallel those of the pig than the cow. The use of such extrapolations has no doubt led to both errors and inconsistencies.

Protein is a dietary essential for both growing and mature animals, regardless of specie. Both the quality and digestibility of a protein directly affect its nutritional worth. Before sound recommendations can be made concerning protein requirements of horses, more information is needed concerning this animal's digestive physiology. In addition, the importance of protein quality and the role of the cecum and its microorganisms in nitrogen utilization must be evaluated.
