Feed efficiency is one of the most economically important traits in beef cattle production. However, genetic improvements in feed efficiency have been limited and slow, primarily because measuring the actual feed intake of individual animals is extremely labor intensive, time consuming and expensive. A better understanding of how various physiological and metabolic processes influence feed efficiency is important to developing inexpensive, rapid methods of reliably predicting feed intake. Genetic relationships between efficiency and other economically important traits such as health and reproductive performance are also relatively unknown.
Funded by the National Check-off and Canada’s Beef Science Cluster, researchers are currently working to Continue reading
