Nutritional Assessment & Energy Calculations (4) Flashcards
Dr. Shepherd
What are the nutrition assessment steps?
- assess the patient
- assess the current and prior diet
- assess the feeding management
- repeat as needed
T/F: Like with adult dogs and cats, BCS can beg used with puppies and kittens
FALSE
What BCS is ideal for dogs and cats?
dogs: 4/9 or 5/9
cats: 5/9
Look at BCS table
What are the 4 grades for muscle condition score (MCS)?
- normal 3/3
- mild muscle loss 2/3
- moderate muscle loss 1/3
- severe muscle loss 0/3
What is MCS used to identify?
cachexia and sarcopenia
Where do you measure muscle condition score on dogs and cats?
dogs: head, neck, shoulders, hind limb
cats: head, neck, shoulders
The nutrient requirements of dogs and cats may be expressed as ____
diet concentration on a caloric basis i.e. 80g crude protein/M cal
What are dogs and cats fed?
What questions do you ask yourself when selecting pet food?
- is it safe?
- is it nutritious?
- is it appropriate for this pet?
What are the 2 categories for AAFCO nutrient profile guidelines?
- growth and reproduction
- adult maintenance
What are WSAVA guidelines?
What is resting energy requirement? (RER)
expressed as kcal metabolizable energy (ME) per day
the foundation to which a life stage factor (aka daily requirement factor) is multiplied to estimate
What is daily energy requirement? (DER)
- DER for adult maintenance aka maintenance energy requirement (MER)
- DER for growth
- DER for work
How is the energy content of pet food expressed?
- gross energy
- digestible energy
- metabolizable energy
- net energy
What is metabolizable energy?
digestible energy - urine & gas energy
How is the energy content of pet food expressed?
metabolizable energy
What is net energy?
metabolizable energy - heat increment (energy lost as heat)
How is metabolizable energy determined?
feeding test
by calculation
What is the resting energy requirement equation?
RER (kcal/day) = BWkg^0.75 x 70
T/F: Energy requirements are linear
FALSE - surface area differences
201 kcal/day
662 kcal/day
How do you calculate DER?
DER = RER x lifestage factor
Look at DER requirement differences
DER 1.4-1.6
2,672-3,054 kcal/day
RER = 234 kcal/day
DER = 280-327 kcal/day
What aspect of the nutrition assessment is important in determining whether the calculated DER is appropriate?
BCS & MCS, weight trends, activity level
