Agriculture Secretary Brooke Rollins $ROL, who also spoke at the news conference, noted that the share of the market held by dominant processors has surged dramatically since 1977, when concentration sat at just 25%. Rollins said the national cattle herd had fallen to roughly 86.2 million head at the start of the year, a level unseen since the Eisenhower era, while more than 100,000 ranching operations had disappeared over the previous decade. Rollins also warned that the companies' sprawling networks of subsidiaries funnel cattle producers into a marketplace with few competitive outlets. "Together, these companies operate through dozens of subsidiary businesses, creating a landscape that leaves many of our cattle producers with limited marketing options," she said.
