Benefits of exposing animals to poor-quality foods early in life
Utah State University Extension
If feeding poor-quality forages (less than 7% crude protein and 50% TDN) are a necessary part of your livestock operation, exposing replacement females to poor-quality roughage early in life with their mothers may make them more productive over their lifetimes. On the other hand, feeding replacement females high-quality diets early in life may actually hinder animals that are expected to produce and reproduce on rangeland that contains poor-quality forages and forages high in toxins.
