Digestive Disturbances : Acidosis , Laminitis , and Bloat

INTRODUCTION In modern North American beef and dairy production systems, cattle typically are fed relatively high concentrate diets to achieve maximum production. Usually grains are processed to increase their digestibility in the rumen and in the total digestive tract; this increases feed conversion efficiency and helps reduce feed costs. However, the potential benefits of increased ruminal starch digestibility must be balanced against the increased risk of digestive disorders in cattle. While it is critical to meet the energy requirements of high producing ruminants, digestive disturbances must be avoided to ensure that meat and milk are produced from healthy animals in an efficient and costeffective manner.
