Pet Food Reviews (Australia)
Carbohydrates don’t need to be listed on the label of pet foods in Australia, but we can use a simple calculation to offer us a rough idea. It’s not perfect, and I’ll explain why, but the following method is how to calculate carbohydrates in a pet food:
100 – Protein % – Fat % – Moisture % – Ash %
There’s a little more to it than that, but that will give us a very good ballpark carbohydrate percentage. Other factors to consider are undisclosed moisture and ash percentages and variance from min & max percentages.
Moisture & Ash
Moisture and ash are usually listed, but as these percentages aren’t required to be listed we can use an average 10% moisture and 8% ash for dry food only. Wet foods contain significantly more moisture.
Min & Max
We often find percentages are listed with a guaranteed minimum or maximum. This makes our simple calculation somewhat vague. If a pet food contains Protein (min) 20% then it’s possible the protein, on average, is higher.
How to Calculate Carbohydrates: An example
Let’s say a dry dog food contains 20% protein, 10% fat, 10% moisture, and 8% ash:
100 – 20 – 10 – 10 – 8 = 52
This product would contain approximately 52% carbohydrates.
So that’s it, that’s how to calculate carbohydrates in a pet food.
If our cat and dog food reviews help, then help us by telling others. The price compare and adverts are our only source of revenue to keep the website running. Thank you 🙂
