US scientists to research cattle genetics to lower feed costs

Genetics tinkering may lead to cattle gaining more weight for less feed.

Some animals gain more weight than other in the same herd, and scientists are looking to unlock the genetics that cause this trait and breed it into other cattle.

Forage agronomist Ron Kallenbach said breeding those genetics into cattle could lower winter feed costs by 10-30 percent when combined with good pasture management.

On pastures, feed-efficient animals require 15-20-percent less forage, he said.

However, Kallenbach warned producers not to focus on only one trait; feed efficiency, for example, has little value if the cow in question produces little milk.

University of Missouri beef specialist Monty Kerley said this study should last for several years at both the University of Missouri and at Texas A&M.
