Question 2

Answer 2

Average Atwater factors

Question 3

Question 4

What is the maintenance energy requirement for an adult neutered male 50lb pet lab in an ideal weight?

Answer 4

Steps:
BW in kg = 50lbs / 2.205kg = 22.6kg
RER= 70 * (22.6kg)^0.75 = 726 kcal/day
MER = (1.4)(726) = 1016 kcal/ day

Question 5

If a dog had a MER of 1016 kcal/day, and their food said:
calorie content = 307 cal ME/cup and 3324 cal ME/kg
How much food should it get a day?

Answer 5

(1016) / (307) = 3 1/5 cups per day
(1016) /(3324) = 0.306 kg/day

Question 6

If a dog food has 14 grams of protein, 13 grams of fat, and 30 grams of carbs, how much energy is in a kilogram of food?
What if it was human food?

Answer 6

14 grams/100 grams = 140g/kg = 140 * 3.5 = 490 kcal protein
13 grams /100 grams = 130g/kg = 130 * 8.5 = 1105 kcal fat
30 grams/100 grams = 300mg/kg = 300 * 3.5 = 1050 kcal carb
490 + 1105 + 1050 = 2645 kcal/kg of food
If human = (140 4) + (1309) + (300*4)= 2930 kcal/kg
