These animals reingest excreted pellets to reclaim unabsorbed nutrients. Foregut fermenters include cows, sheep, buffalo, etc. The fermentation vat is located before the small intestine in a large and elaborate stomach called the rumen . This system is much more efficient, but is slower and requires higher quality forage. Most nutrients are absorbed through the small intestine, and the blood travels from the small intestine to the liver, where detoxification occurs.
Diabetics lack the capacity to produce sufficient insulin for glucose absorption.
Insulin must be injected daily.
