ANSC 3010 TEST 1 QUESTIONS WITH VERIFIED
ANSWERS
What is the challenge that livestock producers and nutritionists face when it comes to
feeding animals? - Answers - To increase the efficiency of conversion of feedstuffs into
animal products.
What is a diet? - Answers - Feed constituent or group of feed constituents that aid in the
support of life
What is nutrition? - Answers - A series of processes by which an animal takes in and
assimilates feed components for promoting growth, milk, or fiber production and
replacing worn or injured tissues
6 classes of nutrients - Answers - Water, carbs, protein, lipid, vitamins and minerals
4 factors that influence food and feed production - Answers - 1) Government regulatory
practices
2) Prices received for products
3) Environmental conditions
4) Input costs (fertilizer, labor, equipment)
True or False: All animals require the same nutrients - Answers - False
What are examples of natural feedstuff? - Answers - corn, soybean, wheat
What are examples of natural processed feedstuff? - Answers - SBM, wheat bran, corn
gluten feed
What are examples of synthetic feedstuff? - Answers - crystalline amino acids, vitamins
What is a ration? - Answers - amount of diet consumed in 24 hr period
What is the most important nutrient? - Answers - Water
In what ways can an animal derive water? - Answers - Drinking
Feedstuffs
Metabolic
What is free water? - Answers - the moisture associated with the feed.
How is metabolic water made? - Answers - Chemically bound and released when
nutrients or body tissue are broken down by metabolic processes
, A general definition for good-quality water is that it should contain less than 2,500 mg/l
(0.25%) of __________. - Answers - Dissolved solids
True or False: Water could be a source of mineral toxicity - Answers - True
Carbohydrates serve as a source of ________. - Answers - Energy
Carbohydrates comprise up to ___% of the dry matter of forages and as much as ___%
in grains - Answers - 70%
80%
Chemically, carbohydrates are composed of _____, _______, and ______ - Answers -
C, H, O
What is the simplest form of carbohydrate? - Answers - monosaccharide; it contains
either five or six carbons, and often referred to as a sugar
What are the 2 most common simple sugars in feed? - Answers - Sucrose (table sugar)
and Lactose (milk sugar)
___________ and ____________ are the two polysaccharides found in plants in the
highest concentrations. - Answers - Starch and cellulose
In monogastric animals, dietary carbohydrates must be converted to ____________. -
Answers - Simple sugars
The primary source of amylase (enzyme) is the_______ - Answers - pancreas
Which animal needs a diet that is
lower in carbohydrates? - Answers - Cat
Simple sugars are absorbed rapidly by the _____________. - Answers - Small intestine
True or False: When young ruminant animals are born, they are functionally
monogastric animals - Answers - True
Microbial organisms cause the ________ in rumen to develop & mature - Answers -
papillae
True or False: In ruminant animals, the amount of amylase and other enzymes secreted
into the small intestine is very high, as compared to monogastric animals - Answers -
False; In ruminant animals, the amount of amylase and other enzymes secreted into the
small intestine is quite LOW, as compared to monogastric animals. As a result, ruminant
animals are LESS able to
digest starch in the small intestine
