Energy and feeding doses Flashcards
What does it mean if a nutrient is conditionally essential?
It is required during certain physiologic or pathologic conditions
What does it mean if a nutrient is essential?
The body can not synthesize it, so it is indispensable
What is the most common analysis done for nutritional testing?
Proximate/guaranteed analysis
although this can be inaccurate on the petfood label
What analysis is more accurate than the proximate analysis and where can it be found?
Average nutrient analysis
This is available from the petfood company: product guides, company websites, or customer service
What is the resting energy requirement (RER)?
Energy used by adult at rest in a thermoneutral environment
What does the RER NOT support?
activity
growth
reproduction
T/F: The RER is the same as basal energy requirement
FALSE
similar but not the same
How do you calculate the RER for a 20kg animal?
(30 x wt in kgs) + 70 = RER
(30 x 20) + 70 = 130 kcal
How do you calculate the daily energy requirement of a patient?
DER = RER x maintenance factor
What variations are considered when picking the most appropriate maintenance factor?
species, age, sex, reproductive status, environment, and activity level
T/F: The DER only represents an estimate for calculating the initial food dose
TRUE
What maintenance factor should be used for any indoor cat that is neutered (even if the BSC is 3/5)
Obese prone bc it is so common in fixed indoor cats
What factors belonging to the animal will make them more prone to obesity?
Breed, genetics, endocrinopathy, age, current medications, activity level, musculoskeletal dysfunction, neuter status, if the patient is already over weight
When calculating the RER, what body weight should be used?
IDEAL body weight
What is the complete and balanced diet concept?
Feeding enough food to meet the patient’s DER - will supply all the nutrient requirements for the patient
