Chapter 7 - Feed Additives

Question 1

Proteins in feed

Answer 1

bypass protein, metal chelator, replacement of natural source material, supplemental enzymes like phytase, and transgenic feeds like BT corn

Question 2

Types of proteins in ruminant feed

Answer 2

indigestible protein, rumen degradable protein, undegraded intake protein/bypass protein

Question 3

Protease

Answer 3

increased amino acid availability with less feed, fewer bacterial toxins, less protein excretion

Question 4

Rigorous Approval Processes

Answer 4

number of regulatory bodies, elaborate animal feed trials. So approval periods are lengthy

Question 5

Attractive value propositions

Answer 5

phytase - phosphate. Proact-protein. Others - energy

Question 6

Improving phosphorus utilization

Answer 6

phytate is not digested by monogastric animals, so phytase is added to feeds. Transgenic plants lower in phytate
