Objective
The aim of the course is to discuss in detail and indepth the metabolism of non-fibrous carbohydrate in ruminants, with emphasis on the use of starch from cereal grains.
Content
Non-fibrous carbohydrates, especially starch, are the main energy sources in diets for high performance ruminants and therefore the efficient use of these compounds is critical to the production systems. In this course techniques that allow to optimize the use of these nutrients will be presented to the students, as well as increase the basic knowledge acquired in previous courses 1. Overview of non-fibrous carbohydrate metabolism in ruminants. 2. Chemical and physical characteristics of the starch in cereal grains. 3. Ruminal fermentation of non-fibrous carbohydrates. 4. Intestinal digestion of non-fibrous carbohydrates. 5. VFA and glucose in ruminants. 6. Post-absorptive metabolism. 7. Sites of starch digestion and energy efficiency. 8. Sources of starch and cereal grain processing methods. 9. Corn grain for ruminants. 10. Dry grain processing methods - Milling. 11. Silage of high moisture corn and sorghum grains. 12. Reconstitution of corn and sorghum grains. 13. Grains steam-flaking. 14. Diet formulation.
