ANSI 3653 Final UPDATED Exam
Questions and CORRECT Answers
There are two greatly different feeding strategies for horses depending on their intended use.
What are typical uses for horses being fed with a traditional feeding strategy vs. a modern,
progressive strategy? - Correct Answer- Traditional feeding strategies are for slow steady
pace horses, NOT for performance or race horses. Modern, progressive strategies are for
rapid growth and performance/race horses.
What are the expected % of mature weight at yearling and 2 year olds for the two feeding
strategies for horses? - Correct Answer- Traditional: yearlings are 50% of their mature weight
and 2 year olds are 75% of their mature weight--mature weight is reached at 3-4 years of age
(Traditional takes longer to reach mature weight but is safe).
Modern: yearlings are 75% of their mature weight and 2 year olds are 100% of their mature
weight--mature weight is reached at 2 years of age (Modern requires more intensive
management and has a risk of developmental issues).
What is a nutrient:calorie ratio and how is it used in the feeding strategy of performance
horses? - Correct Answer- Nutrient:calorie ratio is under the modern, progressive feeding
strategy of horses--maximizes growth by balancing all nutrient requirements.
It provides individualized requirements such as the ratio of lysine, protein, calcium, or
phosphorous to digestible energy (DE).
What is the energy measure used in the formulation of diets for horses? - Correct Answer-
Mcal DE (mega calories of digestible energy).
Determining the energy content of a grain ration for horses is very important. Assuming that a
ration is 75% TDN, what is the Digestible Energy content of the ration in terms of Mcal per
lb.? - Correct Answer- .75 x 2 = 1.5 Mcal DE

It is recommended practice in the proper feeding of mares, to utilize a body condition score.
What is the proper BCS of the foaling mare to optimize reproductive performance? - Correct
Answer- 7.
During late gestation the DE requirement of the mare increases substantially. How much of a
percentage (%) increase in DE requirement above maintenance is associated with the 9th,
, 10th, and 11th months of gestation? - Correct Answer- 9th: 11% increase over maintenance
for DE
10th: 13% increase over maintenance for DE
11th: 20% increase over maintenance for DE
How much milk does a mare produce during early lactation? - Correct Answer- 3% of her
body weight.
In comparison to maintenance, how much of a percentage increase in DE requirement is
associated with the mare's early lactation? - Correct Answer- 100% increase over
maintenance for DE.
Energy expenditure is a function of mass over distance regardless of speed. the level of work
is characterized as light, medium, and intense. provide an example of each form of work.
How much of an increase in DE requirement above maintenance is associate with each of the
categories? - Correct Answer- Light: trail riding: 25% increase over maintenance for DE.
Moderate: ranch work: 50% increase over maintenance for DE.
Intense: race training: 100% increase over maintenance for DE.
Considering the nutrient requirements for exercising horses, what is the difference between
aerobic and anaerobic metabolism and which generates more energy? - Correct Answer-
Aerobic (with O2 or in the presence of O2).
Anaerobic (lack of O2 or O2 intake is inadequate to support demands).
Aerobic generates more energy.
Aerobic metabolism is best for what type of exercise (short duration/high intensity or long
duration/low intensity)? - Correct Answer- Long duration/low intensity.
*********************************
Anaerobic metabolism is best for what type of exercise (short duration/high intensity or long
duration/low intensity)? - Correct Answer- Short duration/high intensity.
