Reducing the period of data collection for intake and gain to improve response to selection for feed efficiency in beef cattle

Abstract Shortening the period of recording individual feed intake may improve selection response for feed efficiency by increasing the number of cattle that can be recorded given facilities of fixed capacity. Individual DMI and ADG records of 3,462 steers and 2,869 heifers over the entire intake re...
