Zootrition - A Dietary Management Software

Ingredients Database

Contains nutritional data on more than 3000 feedstuffs, with data derived from published information for human, livestock, pet, and wild foods.

Energetics Calculator

Estimated daily calorie or joule requirements for a variety of mammals, birds, and reptiles easily calculated by standardized equations, based on body weights, feeding habits, activity levels and/or physiological state.

Nutrient Recommendations Database

Information on published requirements for livestock, pet, and wildlife species of differing production states or physiological stages available for diet assessment/ targets.


Combining amounts and information from the Ingredients Database, you are able to create diets and feeding records including schedules/preparation details. "In-House" Mixes (for example green salad, fruit, vegetable or seed mixes) can be saved separately for use as a single Ingredient in complex diets.


Using the comparison module, composition of multiple feedstuffs and/or diets and/or recommendations can be simultaneously compared in a spreadsheet format.

Feeding Groups

Tools for scaling diet preparation, ingredient bulk ordering, and food delivery reports are available by linking basal diets with animal inventory, location and enclosure details.


Customizable Summary and Detailed reports can be created for printing/saving/sharing within various modules (Diets, Ingredients, Recommendations, Comparisons, Orders).

Reference Library

Example Consultation, Research, and Evaluation Forms available as downloads, along with information on Nutrient Toxicities, Stability, Feed Handling/Storage, Calculation of Energy Needs, Enrichments, and source of all material provided.

(...) It's an easy-to-use software, and it has lots of information. For sure, the animals in our care are thankful for it too.
