The perception exists that feed produced for livestock competes for human food supplies and represents an inefficient or wasteful use of resources.
This perception can create confusion in communicating with retailers and other supply chain partners, policymakers, and consumers.

In this CAST publication, scientific experts examine the facts and provide science-based information on which reasoned choices can be made in determining appropriate resource allocations regarding livestock production.

The global livestock industry faces a considerable challenge because a presumed dichotomy exists between the increasing demand for animal source foods conferred by population growth and consumer concerns regarding livestock production sustainability. Many consumers are unaware of the advantages of livestock productivity gains conferred by modern practices, by-product feeds, and use of technology.
