I thought this study was interesting. It's a shame we don't/can't recycle more food waste into livestock feed.
Abstract - There is renewed interest in utilizing food waste as animal feed due to its potential benefits in reducing feed cost and environmental impact while improving global food security. This study was conducted to examine the efficacy of recycled food waste-based feed for laying hen performance, egg quality, and nutrient digestibility.
Feeding recycled food waste improved feed efficiency in laying hens from 24 to 43 weeks of age
