Abstract

Breed differences, heterosis, and reciprocal cross differences from beef cattle crossbreeding experiments have been summarized in prior reports from U.S. Meat Animal Research Center and reports from other research stations.

However, there have been only limited reports to characterize the Red Poll breed relative to other breeds. This report summarizes results from an experiment where reciprocal crosses and straightbreds were produced to estimate heterosis, breed maternal effects, and breed effects for growth rate of the Red Poll and Hereford breeds.
