Question 1

What are 9 essential amino acids?

Answer 1

Phenylalanine
Valine
Threonine
Tryptophan
Isoleucine
Methionine
Histidine
Leucine
Lysine

Question 2

What is limiting amino acid?

Answer 2

amino acid that become deficient first as dietary crude protein concentration is reduced

Question 3

What is a synthetic form of lysine?

Answer 3

L-lysine-HCl

Question 4

What is bioavailability?

Answer 4

the proportion of an analyzed element that is available in a form that can be digest and absorbed by the animal

Question 5

What is fecal digestiblility?

Answer 5

a way to measure total tract digestibility
FD,% = (Consumed-Excreted)/Consumed

Question 6

What is ileal digestibility?

Answer 6

a more accurate way to measure digestibility, can be measured by euthanasia or through a canula

Question 7

What is apparent ileal digestibility?

Answer 7

assumes all amino acids are from digestion

Question 8

What is true ileal digestibilty

Answer 8

does not include undigested feed lysine or endogenous losses

Question 9

What is standardized ileal digestibility?

Answer 9

does not include basal endogenous losses

Question 10

What are the endogenous fractions?

Answer 10

1. basal endogenous losses
2. diet induced dietary losses

Question 11

How do you calculate SID?

Answer 11

(lysine intake - ileal lysine - basal endogenous lysine) /
lysine intake
