Document Summary
Processing feed: breaking the hull and exposing the starchy cell content of a seed. Of all of the cereal grains, corn has the highest starch content and the thickest seed coat. Ways to process corn: cracked, ground, popped, flaked. Pre-cecal starch digestion is increased with feed processing. Mechanical, thermal, and hydrothermal processing decreases particle size, breaks complex bonds, and exposes the starch in feedstuffs. Benefits of feed processing include a reduced chance of colic and laminitis, more sable glucose levels, and food that is easier to chew. Fecal balls are formed in the small colon and stored in the rectum. Metabolic rate and activity level effect nutrient requirements. Fat is 2. 25 times more energetically dense than glucose. Protein is used for fetal development, lactation, growth, and muscle repair. The body does not generally use protein for energy. Water is a transport mechanism, manages blood volume, and maintains the health of the gi tract.
