We discussed the information needed to formulate diets.
What is the first step in balancing a diet for animals (in other words, what do you need to know first
about the particular animal you are balancing for)? - Answers obtain reliable source of nutrient
requirements
We discussed the information needed to formulate diets.
In the US, what is the primary source of this information needed to balance the diet? (Spell out, don't
just give initials) - Answers national research council
We discussed the information needed to formulate diets.
So after you have step 1 figured out, what other information is needed to balance the diet ? -
Answers what ingredients you have and their nutrient density
Why are ruminant diets typically balanced on a dry matter basis? - Answers moisture can vary
What is meant by the term "ad libitum"? - Answers a feeding technique in which the animal has
access to as much food as he or she desires to eat
Generally, poultry will eat to meet their __ needs - Answers energy
Fats are routinely added to poultry diets. To which of the following are minimal amounts of fat added
to their diets?
Broilers
turkey
Layers
all have added fat at high levels - Answers layers
When adding fat to diets, what should happen to the amino acid requirement as a % of the diet?
Why? - Answers it should increase because chickens eat to meet their energy requirements and when
the fat content is increased, the energy is increased per pound of feed and feed intake will decrease.
When feed intake decreases, there is a chance of amino acid deficiency
Feed costs represent ___% of the total cost of poultry production in the United
States. - Answers 50-75
Trace minerals are added to poultry diets at ______% of the diet. - Answers 1-4%
On average, 60 to 70% of commercial poultry diets consists of:
Cereal grain
fat
Protein supplement
feed additives to promote growth - Answers cereal grain
In poultry, why are nutrient requirements for energy expressed in terms of metabolizable energy (ME)
rather than digestible energy (DE)? - Answers because feces and urine are excreted together so it is
impossible to distinguish how much energy is lost in one or the other
Energy requirement for layers is:
2500 kcal/kg
3200 kcal/kg
2800 kcal/kg
3400 kcal/kg - Answers 2800
Amino acid requirements are different in poultry than in most other species. In addition to the normal
10 essential amino acids, our guest speaker mentioned 2 that are required in poultry diets. What are
they?
Lysine and methionine
taurine and glycine
Glycine and serine
, serine and valine - Answers glycine and serine
What is the most limiting amino acid for poultry fed corn/SBM diets? - Answers methionine
What is the second most limiting amino acid for poultry fed corn/SBM diets? - Answers lysine?
When crystalline amino acids are used in poultry diets, what happens to the CP content of the diet? -
Answers increases
What is the average range for market weight for commercial poultry?
2 to 3 pounds
4 to 6 pounds
5 to 8 pounds
We want big 10 pound chickens! - Answers 4-6
In the typical corn-soybean meal diets for poultry, the TSAA are the first limiting amino acids. Which 2
amino acids are these TSAA (total sulfur amino acids)?
Lysine and methionine
Methionine and arginine
serine and glycine
Methionine and cysteine - Answers lysine and methionine
The total sulfur amino acids are limiting in corn/SBM diets for poultry (because of the high content of
these AA's in feathers)
Which one is typically added in crystalline form to poultry diets. - Answers
During days 0 to 49, commercial poultry have a FCR of 2.0 or less.
What does FCR stand for? - Answers feed conversion ratio
During days 0 to 49, commercial poultry have a FCR of 2.0 or less.
If the FCR =2, how many pounds of feed must the chicken consume to gain 5 pounds? - Answers 10
lbs of feed
During days 0 to 49, commercial poultry have a feed conversion ratio (FCR) of 2 or less.
What does a FCR of 2.0 mean? - Answers
During days 0 to 49, commercial poultry have a feed conversion ratio (FCR) of 2 or less.
How does this FCR in commercial poultry compare to beef cattle? - Answers
During days 0 to 49, commercial poultry have a feed conversion ratio (FCR) of 2 or less.
If a chicken has a FCR of 1.5, how much feed does it take to produce 6 pounds of meat? - Answers 9
lbs
