ANS 313 Exam 1 questions with complete solutions
You have two growing chickens. You feed both the same diet, but one eats at
1.5X maintenance and the other at 2X maintenance. You feed them both until
they reach a market weight of 7 pounds. In the end, which chicken eats the most
and costs the most to get to the 7-pound market weight? - ANSWER-chicken at
1.5X
You have two growing chickens. You feed both the same diet, but one eats at
1.5X maintenance and the other at 2X maintenance. You feed them both until
they reach a market weight of 7 pounds. Which produces the least fecal and
urinary chemical energy waste per pound of meat produced? - ANSWER-chicken
at 2X
In your dream job as a nutritionist at the National Zoo of Australia, you feed
koalas in calorimetry chambers 0, 100, or 200 grams of dry matter per day of a
herbivore diet that is 5 kcal/gram. Those levels correspond to fasting, 1X and 2X
maintenance intakes. You obtain these results. Fecal energy output per day = 0
kcal for fasted, 100 kcal for 1X, and 240 kcal for 2X. Total heat production per
day = 200 kcal for fasted, 330 kcal for 1X, and 490 kcal for 2X. Retained energy
per day = -200 kcal for fasted, 0 kcal for 1X, and 150 kcal for 2X. What is ME
intake at 1X intake (kcal/day)? (Hint: put this info into a table to use for the 4
questions on this problem). - ANSWER-330

This compound accounts for most of the energy and nitrogen lost in urine.
Answer is one short word. - ANSWER-urea
As feed intake and daily gain in a pig increase, feed efficiency increases because
of the "dilution of maintenance". - ANSWER-true

You have two growing chickens. You feed both the same diet, but one eats at
1.5X maintenance and the other at 2X maintenance. You feed them both until
they reach a market weight of 7 pounds. Which chicken would have the lowest
thermoneutral zone on the third day of the study? - ANSWER-chicken at 2X
The primary monosaccharide found in starch and cellulose. - ANSWER-glucose
This nutrient has 2.25 times as much energy per gram as does carbohydrate, and
it is hydrophobic. Thus, animals can store this with 10 times as much energy per
pound of body weight compared to carbs. - ANSWER-lipid, fat
A short chain fatty acid of 4 carbons. Was first isolated from butter. - ANSWER-
butyric acid, butyrate
Methionine is an amino acid that contains not just C, H, O, and N but also this
atomic element. - ANSWER-sulfur
Compound with one H2O for every C. - ANSWER-carbohydrate
Fatty acid with 3 carbons, so it is called a short-chain fatty acid. This is the only
common fatty acid that is glycogenic. - ANSWER-propionic acid
