Lecture 3- Energy Calculations

Nutritional goals for dog and cats

Avoid deficiencies and toxicity

promote longevity

promote health

when health can not be achieved, modulate disease

What three things are energy derived from

Protein

fat

carbohydrates

What is energy measured in

Kilocalories ir kilojoules

What is netabolizeable energy

energy that is actually utilized by the body

What does ME depend on

nutrient composition and species of animal consuming the food

What will ME also vary with

overall digestibility and the animal’s individual metabolic efficiency

What is RER

resting energy requirement

Body surface ______ as body weight increases

decreases

IS the RER calculation the same for bith dog and cats?

Yes

What is the RER based off of

energy requirement for a normal but unfasted animal at rest in a thermoneutral environment

What energy needs are included in RER

Needed for digestion, absorption, and metabolism of food and recovery from previous physical activity
