That's primarily the term of waste from a lean-thinking perspective, which is optimizing the use of all resources. For instance, we know there's a difference in the volume of different types of barley fed to certain breeds of animals, such as certain breeds of cattle, so you're choosing the best variety of grains for the most appropriate genetics in the most appropriate production system.
There are great examples of where it's occurring around the world. We just developed a video on a case study where two years ago the Beef Farmers of Ontario, through a U.K. initiative, reduced the cost of producing a finished beef animal by approximately $400 per head. The primary way they reduced that was by better using the feed more effectively.
