Sequencing of the Cattle Genome Toward Finding Ways to Increase Feed Efficiency of Cattle

Considering the continuous increase in feed cost, the greatest part of the cattle production cost and the growth of environmental concerns, improvement of feed efficiency has potentials not only for increasing profits for cattle producers but also for decreasing environmental impacts of cattle production. The recent sequencing of the cattle genome provides the first opportunity to explore the relationship between genetic and feed efficiency of cattle. This short review aims to describe recent findings from the sequencing analysis of the cattle genome and to illustrate how this new information can be applied increase feed efficiency of cattle.
