Answer 19

Net energy system

Question 20

Van Soest

Answer 20

replaced crude fiber system

Question 21

an animal eats to meet an energy requirement

Question 22

Lavoisier

Answer 22

founder of the science of nutrition

Question 23

Kjeldahl

Answer 23

CP analytical procedure

Question 24

High levels of nitrate in water provided to animals can be very toxic to ruminants because of its effect on the rumen microbial population. Non-ruminants are much more tolerant because they don’t have a rumen

Answer 24

False

Question 25

The opposing hormones aldosterone and natriuretic hormone play an indirect role in regulating ECF level by retaining or excreting (respectively) sodium, while the presence or absence of vasopressin (ADH) signals the kidney to retain or excrete (respectively) water independent of sodium levels

Answer 25

True

Question 26

Two rival producers are feeding a similar age group of market hogs. Producer A feeds a corn based ration that exactly meets the energy requirement of the hogs. Producer B feeds a similar ration but decided to add some fat to her ration to boost the energy content of her feed even higher

Which group will have higher DM intake

Answer 26

A

Question 27

Two rival producers are feeding a similar age group of market hogs. Producer A feeds a corn based ration that exactly meets the energy requirement of the hogs. Producer B feeds a similar ration but decided to add some fat to her ration to boost the energy content of her feed even higher

Which group will have higher energy intake

Answer 27

Equal

Question 28

Two rival producers are feeding a similar age group of market hogs. Producer A feeds a corn based ration that exactly meets the energy requirement of the hogs. Producer B feeds a similar ration but decided to add some fat to her ration to boost the energy content of her feed even higher
