Question 4

What is the difference between RER + MER?

Answer 4

RER = Resting Energy Requirements
1. Energy required by an animal in a thermo-neutral environment 12 hrs after eating
1. Value used for calculating energy needs of hospitalised px

MER = Maintenance Energy Requirements
1. Also reffered to as DER (Daily Energy Requirements)
1. RER + energy required for exercise, digestion + absorption of food

Question 5

What is RER?

Answer 5

Resting Energy Requirements
1. Energy required by an animal in a thermo-neutral environment 12 hrs after eating
1. Value used for calculating energy needs of hospitalised px

Question 6

What is MER?

Answer 6

Maintenance Energy Requirements
1. Also reffered to as DER (Daily Energy Requirements)
1. RER + energy required for exercise, digestion + absorption of food

Question 7

What is DER also known as?

Answer 7

MER

Question 8

What is the RER calculation for dogs + cats between 2kg - 30kg?

Answer 8

RER = (BW (kg) x 30) + 70

Question 9

Calculate the RER for a 22.6kg dog?

Answer 9

RER = (BW (kg) x 30) + 70
1. RER = (22.6 (kg) x 30) + 70kcal
2. = 678kg + 70kcal
3. = 748 kcals p/day
