2. Is it profitable to grind, crush, or soak feed?

3. When animals fail to chew grain thoroughly some of the nutritive value of the feed is lost because of reduction of surface area

4. Fineness of grain – why? Should be ground medium fine Swine should be ground more finely 700 t0 800 microns Fine grinding takes more energy Energy is EXPENSIVE Time and process can make grains less palatable Wheat and barley ground to fine can be lost as dust, or cause digestive problems

5. Rolling vs Grinding Monogastrics Rolling grains results in a more uniform particle size which improves digestibility Rolling grain is more energy efficient than using a hammer mill or grinder

6. Advantage of Pellets Less waste Less space needed for storage Animals may eat more feed in pellet form

7. Hay Chopping or grinding hay is only advisable if it encourages animals to eat coarse, stemmy portions that might otherwise be left

8. 100% Concentrate Is not advisable because of digestive troubles in animals, especially ruminants

9. Cooked Feed Advantageous when feeding Potatoes Field beans Soybeans Cooking removes factors that cause poor performance in swine Cooking does not increase the digestibility or feeding value of other feeds

10. Soaking Feeds Advantageous when grain with small or hard kernels cannot be ground or crushed If soaked too long, fermentation may take place or mold will grow which produces toxins

11. Fermenting of Feeds Experiments show that this does not cause any saving in feed or result in greater production
