Defining Feed Efficiency
Gordon Carstens, Texas A&M University, presented information defining feed efficiency at the general session “Where Do I Fit With My Production Environment?” at the BIF symposium, April 20.
Feed inputs and outputs are measured in targeted stages of the beef production cycle, Carstens said. Since it is not practical to measure forage intake of mature cows, emphasis is placed on growing animals.
“Expectations are that appropriate use of a feed efficiency trait in growing cattle, which accounts for genetic variation in efficiency of feed utilization to support maintenance and growth requirements, will generate progeny that are efficient in all segments of the industry,” Carstens said.
