Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:

Hoornbeek, Frank K. (Frank Kent), 1928-

Abstract:

The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...
