breakdown of carbs releases volatile fatty acids (VFA)
evolutionary development allows animal to consume forage rapidly then re-chew at later time
cattle fermentation takes place ____ the true stomach so they utilize bacteria as protein source
horses fermentation takes place ____ true stomach so bacteria cannot be absorbed from large intestine
produced in gastric mucosa cells in hourses, stimulates *acid secretion by stomach (time to eat/digest/absorb)
inhibits *acid secretion, stimulates bicarbonate production, presence of chyme and acid in duodenum stimulate its secretions
