This second edition of 'Horse Feeding and Nutrition' provides information for those interested in the feeding and nutrition of horses. It has been revised to include new research information that has become available since publication of the first edition. Three new chapters have been added, entitled 'Feeding and Health-Related Problems,' 'The Complexity of Proper Bone Formation,' and 'Exercise Physiology'. New feed and food crops, improved methods of production and processing, increased productivity of animals and crops, changes in animal products including more lean and less fat in meat and less fat in milk, longer shelf-life requirements of animal food products, and a myriad of new technological developments have resulted in a need to continually re-evaluate nutrient requirements and supplementation. Suggested levels of protein, minerals, and vitamins for use in horse diets are presented. These can be used as guides which can be modified to suit the various feeding situations encountered in horse farms.
