This is the concise, easy-to-use version of Dr. Lewis’s Equine Clinical Nutrition, Feeding and Care.

The book can help prevent common, but expensive problems in horses of all ages.
There has been an extensive amount of research conducted, as well as experiences and recommendations reported, on all aspects of feeding and caring of the horse. Much of this information is accurate and applicable, however, some is not. Some must be interpreted or combined with other information to be directly applicable and useable. Results with other species of animals are sometimes reported for horses. Often these are found not to be applicable for horses. Some experiences, recommendations, and “old wives’ tales” are well proven not to be true, or to be true only under certain circumstances, but unfortunately are often repeated by those unaware of studies or experiences refuting them. Occasionally, fmancial gain rather than scientific validity appears to be the motive behind information and recommendations given. Generally, there is some factual basis for the statements or implications made, but what has been demonstrated is not understood, is misrepresented, is exaggerated, or most often, is extrapolated to circumstances to which they either don’t apply or to which there is no evidence that they do. This book is an effort to alleviate these shortcomings in bringing together research results, experiences, and recommendations in as accurate, complete, and as useable a manner as possible for horse owners, who are not veterinarians or nutritionists.
