This document discusses factors that influence how much feed livestock can eat each day, including feed quality, the animal's size and production level, and environmental conditions. It provides a table showing approximate dry matter intake for different quality forages. For example, a 400kg animal eating low-quality feed can intake 6kg of dry matter daily, while the same animal on good quality feed can intake 10kg of dry matter. Feed quality has the largest impact, as higher quality forage allows animals to consume more dry matter and crude protein each day.
