Open Live Camera →Operating Protocol & Usage Instructions
- Input patient body weight in kg and select clinical Body Condition Score (BCS 1-9).
- Adjust life-stage activity multiplier based on physiological state (growth, gestation, working, geriatric).
- Review calculated Resting Energy Requirement (RER) and daily meal portion mass in grams.
Scientific & Clinical Inquiries (FAQ)
What is the mathematical definition of RER?
Resting Energy Requirement is calculated via Kleiber's Law: RER = 70 × (Body Weight in kg)^0.75, representing basal metabolic turnover at rest.
How does BCS alter the daily calorie target?
Patients above ideal BCS (5/9) receive a negative adjustment factor (-5% per BCS point) to encourage safe adipose catabolism without inducing hepatic lipidosis.
Why is food energy density critical?
Calorie density determines physical gastric volume needed to deliver adequate nutrients; low-density foods risk volume insufficiency in high-demand animals.
