1
Q

Are dogs bulk limited? *

A

No. They are designed to eat large, infrequent meals

2
Q

energy budget is comprised of: *

A

energy in: metabolizable energy in food

energy out: requirements under different conditions

3
Q

3 methods to determine how much to feed. Which is best for estimating energy needs of an individual animal? *

A

1) a good diet history: multiply energy density of each ingredient by amt. eaten and total (best)
2) calculation from BW (calculate MER of an average animal)
3) look at package

4
Q

requirement = *

A

energy density (kcal/g) x amount fed (g)

5
Q

cans, cups, or g/day to feed = *

A

avg. maintenance energy requirement (kcal/day)/ energy density (kcal/can or cup or g)

6
Q

energy required for maintenance of body weight can vary by up to __% of mean? *

A

40%

7
Q

When should you use a calculation from BW to determine how much to feed? *

A
  • when introducing new food
  • inappetant or obese patients
  • hospitalized patients
8
Q

main problem of using a calculation to determine how much to feed *

A

only gives a mean of a population, not a measure of INDIVIDUAL requirement

9
Q

label reccomendations are based on: *

A

a calculation of population mean. Not necessarily accurate for the individual

10
Q

DER = **

A

daily energy requirement. Includes growth/production

11
Q

MER = **

A

maintenance energy requirement = DER - energy needed for production/growth. Amount of energy necessary to maintain equilibrium over a length of time.

12
Q

RFMR = **

A

resting fed metabolic rate (aka resting energy requirement (RER) or resting energy expenditure (REE)?). Same as basal metabolic rate but not post-absorptive. How much to feed a dog in a cage

13
Q

BMR = **

A

basal metabolic rate. Energy required to maintain homeostasis/minimal metabolism when p is postabsorptive, awake, lying down, in thermoneutral unstressed environment

14
Q

thermonuetral environment *

env. where animal doesn’t have to expend energy to stay warm or cold

15
Q

Does REE directly relate to body weight? *

A

No. Increasing energy requirements more directly related to increasing body surface area

16
Q

REE = *

A

resting energy requirement. Doesn’t have a solid definition. Doesn’t distinguish whether they’ve been fed or not

17
Q

A

LBM

39
