Max, a 2-year-old, active, castrated male Jack Russell Terrier, weighs 16 pounds and has a BCS of 4/9. What is his approximate calculated daily energy requirement? (MER/DER = 1.6)
496 kcal/day
To calculate Max’s approximate daily energy requirement (DER), we can use the following formula:
DER = RER x Resting Energy Requirement
RER (Resting Energy Requirement) can be calculated based on Max’s body weight using the following formula:
RER = 70 x (body weight in kg)^0.75
First, we need to convert Max’s weight from pounds to kilograms:
16 pounds ÷ 2.205 = 7.25 kg
Next, we can calculate Max’s RER:
RER = 70 x (7.25)^0.75 = 337 kcal/day
Now we can calculate Max’s approximate daily energy requirement (DER):
DER = 1.6 x RER = 1.6 x 337 kcal/day = approximately 539 kcal/day
Therefore, Max’s approximate calculated daily energy requirement is approximately 539 kcal/day. It’s important to note that this is an estimation and may need to be adjusted based on Max’s specific activity level, health status, and other individual factors.
