The animal breeding industry worldwide is restructuring, with consolidation occurring both vertically and horizontally. This process is occurring during a time of simultaneous breakthroughs in reproductive technologies, genomics, bioinformatics, and molecular biology. The result will be a much smaller group of companies that will have evolved from traditional artificial insemination organizations into breeding companies with nucleus herds. These companies will offer a variety of products including marker-assisted selection (MAS), embryos preselected for certain traits, clones, gender-specified semen and embryos, and reproductive technologies which will improve fertility. The overall impact of these technologies will be to add value to a pregnancy and improve the uniformity and quality of beef.
