I’ve been using this sheet since it was released and it has become an essential part of my day to day work. I use it in my day to day veterinary to audit and formulate diets, and more recently it has also become an invaluable tool for teaching other veterinary professionals and owners how to formulate diets safely to recognized nutrient standards. A superb and versatile science based sheet!

NRC, FEDIAF, and AAFCO Nutrient Requirements

Compare recipes using any set of nutrient requirements, including NRC or FEDIAF for homemade and AAFCO for commercial analysis. The sheet automatically adjusts how nutrient requirements are calculated according to the energy requirements of the pet- a core feature missing from all other competitor’s products. 

Create Unlimited Amount of Cooked and Raw Recipes, Pets, & Ingredients

Create as many recipes as you want for as many pets as you want. Comes with hundreds of commonly used ingredients. New ingredients can be added quickly and easily using the RFN add-on. No need to manually type in nutrient analysis from the USDA database. This formulation sheet can be used with adult diets, including those with a PMR or BARF base.

The single formulation sheet comes with sample, balanced formulations for you to further customize.

Automatic Nutrient Goals Adjustments

Color coded nutrient ratios to help guide the formulator in making a balanced formulation, rather than just focusing on meeting nutrient requirements. Adjusts nutrient goals to account for dark fur colors, higher levels of certain nutrients (such as certain fatty acids), and accounts for different biological activity of nutrients, such as the various forms of omega 6 fatty acids.

Personalize Nutrient Goals with Feedback

Create custom fiber, calorie, and macronutrient goals. Direct control over bioavailability settings to account for nutrients with higher or lower bioavailability depending on ingredient selection. Submit formulations to the RFN community and receive feedback from experienced professionals and pet owners.

AAFCO Commercial Food Converter and Kibble Fresh Food Toppers

Input commercial foods or analyses easily. Perfect for fresh food topper formulations where kibble is the base of the diet.

Cloud Based: Mobile and Desktop Viewing

The RFN sheet provides multiple builders for when you want to work on desktop, mobile, or tablet. Access your sheet from multiple devices with just one purchase.

Export your formulations to create batch shopping & prep lists. Printable, detailed full nutrient analysis and guidelines. Perfect for sharing with your veterinarian and keeping a detailed nutrient history for your pet.
