Feed conversion ratio (FCR) is the core indicator of feed economy. The finer and more uniform the particles, the fuller the contact with digestive enzymes and microbes, and the higher the conversion rate.

Research shows that reducing chop length from 20mm to 6-12mm can raise fiber digestibility by 8% to 12%, meaning animals produce more meat or milk from less feed.

For large-scale farms this directly lowers the feed cost per kilogram of milk and per kilogram of weight gain.
