T or F: The most palatable feeds available will be used for the high-producing dairy cow in order to achieve high feed intake along with high production
True
T or F: A good source of protein in swine and poultry diets is urea
False
T or F: A feed with about the same feeding value as soybean meal for beef cattle is cottonseed meal
True
T or F: Without microbes in the rumen, ruminants could not digest hay and other feeds containing cellulose any better than we can.
True
T or F: Corn and other grains are fed primarily for the protein content
False
T or F: A good substitute for corn with about the same feeding value is grain sorghum (milo)
True
T or F: Lignin is completely indigestible, increases in a plant as it matures, and decreases the feeding value
True
T or F: A balance of amino acids in the protein of the ration is more important to the horses than it is to the cow
True
A big difference between ruminants and nonruminants is that ruminants rely on _______ much more for their source of energy
Volatiles Fatty Acids (VFAs)
Crude protein is determined by
Multiplying the % nitrogen by 6.25
A polyunsaturated fatty acid has (think about carbons and hydrogens)
Double bonds between carbons and less hydrogens than it could have
Excess protein in the diet
Is broken down and used for energy
What could result from limiting water to livestock
Poor growth, poor feed intake, increased body temp, and death
The difference between starch and cellulose is
Both are composed of glucose, and in starch, the glucose are connected with alpha bonds, whereas and cellulose, the glucose are connected with beta bonds.
What energy value best represents what an animal can actually use for productive purposes?
Net Energy
Which vitamin is not needed in the diet of any farm animals, but is needed in the diet of humans to prevent scurvy
Vitamin C
What substance emulsifies fat
Bile
What enzymes digest carbohydrates
Amylase
What substance digests fats from triglycerides to free fatty acids
Lipase
What is the end product of rumen fermentation of carbohydrates?
VFAs
Which amino acid is required and contains sulfur
Methionine
Which great person of the past provided his insight to investigate nutrition by feeding simplified diets, containing only corn and corn plant, or only wheat and wheat plant, or only oats and oat plant, which showed corn-fed cows performed better, and led to the astounding discovery of whole class nutrients, the vitamins, that were previously unknown?
Dr. Stephen Babcock
The reason B vitamins are not added routinely to beef cattle diets is that
Beef cattle are provided with the B vitamins naturally through the bacterial fermentation that takes place in their rumen
Water plays an essential role in
Maintaining body temperature
Many of the chemical reactions in the body
