How Much to Feed a Australian Cattle Dog: WSAVA Caloric Requirements
Energy intake calibration formulated via the WSAVA nutritional equation (Resting Energy Requirement: 70 × [weight in kg]^0.75) multiplied by physiological activity indices. Gram estimates assume standard commercial dry kibble (3,600 kcal/kg).
| Life Stage / Activity Level | MER Multiplier | Daily Energy (kcal) | Estimated Kibble (Grams/Day) |
|---|---|---|---|
| Neutered / Spayed Adult (Maintenance) | 1.6× RER | 891 - 1163 kcal | ~248 - 323 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 1003 - 1309 kcal | ~279 - 364 g |
| Active / Working Dog | 2.2× RER | 1225 - 1599 kcal | ~340 - 444 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 780 - 1018 kcal | ~217 - 283 g |
| Weight Management / Obese Prone | 1.1× RER | 613 - 800 kcal | ~170 - 222 g |
| Growing Puppy (4+ Months) | 2× RER | 1114 - 1454 kcal | ~309 - 404 g |
