Crude Protein (in Dog Biscuits)
Definition
Crude protein in dog biscuits is defined as the total percentage of nitrogen containing compounds in the dog biscuits. This can be determined by the Kjeldahl or Dumas method and expressed as a percentage of the total weight of the product. The FSSAI Standard 2.2.10 and the AAFCO Dog Food Nutrient Profiles (2023) for complete and balanced dog foods (including treats such as biscuits) require minimum crude protein to be stated in the Guaranteed Analysis on the product’s label. For training biscuits, veterinary nutritionists recommend a minimum of 18% crude protein (on a dry-matter basis).

When we talk about crude protein, we’re looking at a lab test result, not a direct measure of how good or digestible the protein is. The way it’s measured is by using the Kjeldahl method, which checks the total amount of nitrogen in the product and then multiplies it by 6.25 to get an estimate of the protein content. The thing is, this method can be a bit misleading because it also picks up on non-protein sources of nitrogen like urea, ammonium salts, or collagen, which don’t actually provide the useful amino acids that our bodies need. On the other hand, high-quality dog biscuits get their crude protein from named animal sources like chicken meal, which has around 65-70% crude protein, fish meal with 60-65%, or lamb meal with 55-60%. These sources are considered to have high biological value, meaning they provide the good stuff – biologically useful amino acids – that dogs need. So, when choosing dog biscuits, it’s essential to look for these named animal protein sources to ensure your dog is getting the best nutrition possible.
When you’re shopping for dog biscuits in India, it’s essential to check the label for the “Minimum Crude Protein %” as required by the FSSAI Standard 2.2.10. But what does this really mean for your pet? The AAFCO Dog Food Nutrient Profiles for 2023 sets a minimum standard of 18% dry matter for crude protein in dog treats, which is meant for adult maintenance. So, if you want to compare different brands, you need to look at the crude protein levels on a dry-matter basis, not as-fed basis. This is crucial because different brands have varying moisture levels, and you want to make sure you’re giving your dog the best nutrition possible. By comparing the crude protein levels correctly, you can make an informed decision about which dog biscuit is the best fit for your furry friend.

Q: How do I convert as-fed crude protein to dry-matter basis for dog biscuits?
Formula: Dry-Matter CP% = (As-Fed CP%) / (1 − Moisture%) × 100. A simple example with a biscuit: 22% as-fed CP and 10% moisture: 22 / 0.90 = 24.4% dry-matter CP. As already mentioned above, when comparing the protein content of products with different moisture contents with other products on the market (offered by other manufacturers!) always calculate on the dry-matter basis! .
Key Takeaways
- Crude protein is calculated by total nitrogen times 6.25. This measure does not express digestibility or availability of essential amino acids.
- For Adult Maintenance (treats and biscuits) as per 2023 specifications, the minimum crude protein content is 18% DM as supplied.
- Individual specific named protein sources such as chicken meal or fish meal have a higher biological value than general unnamed by-products from tissues etc. which have unknown composition and value.
- Dry matter is the basis for comparison of crude protein on pet foods so that companies can compare with other products on the market. As-fed values do not allow for comparison because of the variable amount of moisture in different products.
