Animal Feed Formulations Library 

Sample feed formulations for commonly farmed animal species, provided as reference materials

Developed by  Ioannis Mavromichalis, Ph.D.
Presented by WATT Global Media

The Animal Feed Formulation Library is a group of commercial feed formulas for major farmed animals. They were developed to represent common current practices in the United States and Europe. Their role is to provide an educational example for those not directly engaged in commercial animal nutrition. As such, these formulas remain incomplete and generic, focusing only on the basic principles of nutrition.

A qualified nutritionist with knowledge of local conditions could use these formulas as a starting point to create farm-specific finished results with authority and responsibility.

To start, please review the disclaimer below and read the General Information page to understand how these formulas were created and what they can or cannot be used for before perusing these formulas.

General information: How the broiler feed formulas were created

In 2020, WATT Global Media and Ioannis Mavromichalis, Ph.D. decided to publish a series of animal feed formulas as a general information resource material. The first set of diets is focused on broilers. These formulas are not complete, but the exclusions, such as additives and vitamin/mineral premix specifications, are either covered in other publications or will be published in the future as part of this library of feed formulas.

This article acts as a guide to describe Mavromichalis’ approach to the development of the series and frames how to use the information found throughout.

Broiler feed formulations and analysis

Each separate broiler feed formulation feature includes analysis of the defined diet and includes sample formulations of rations at different points in the life cycle of the broiler chicken: starter, grower and finisher.

Available for download

Additions to the Animal Feed Formulations Library

Broiler Feed Formulations is the first installment in a greater feed formulation series. In 2020, we aim to complete additional species throughout the year and enhance existing formulations with further developments (e.g. with phytase and other enzymes) and extensions (to include other cereals or protein sources) based on audience interest and feedback.
