5. digestion and absorption
ANS a) digestive enzymes
b) nutrient transporters
6. limitations of young gut biology
ANS - inadequate exogenous enzyme secretion
- reduced absorptive capacity
- inadequate HCL secretion
- inadequate food and water intake
7. inherent digestive inefficiency
ANS there is presence of indigested protein, starch,fat, phosphorus, etc.
8. peculiarity of feedstuffs
ANS -phytate
-fibre and resistant starch
-inhibitors and toxins

9. result of undigested nutrients
ANS pathogen overgrowth = increased flow of DM tohind-gut
10. problematic feed ingredients
ANS rye based diets, soluble NSP in cereal grains
11. why does high soluble fibre reduce growth and nutrient digestion in poul-try?
ANS - high exogenous secretions
- binding of endogenous enzymes
- nutrient encapsulation
- delayed absorption
12. fat digestion (emulsification)
ANS fat in duodenum stimulates secretion of chole-cytstokinin which regulates secretion of
pancreatic enzymes and bile acids (whichemulsify fat droplets)
13. implication of bacterial overgrowth in SI is fat digestion, which resultsin
