DALLAS (AP) – A federal report reveals infighting and poor oversight contributed to the mistreatment of animals at a Texas A&M University campus.

A September inspection by the U.S. Department of Agriculture found that Texas A&M-Commerce, which is northeast of Dallas, violated provisions of the Animal Welfare Act.

The USDA said in one instance a horse suffered because a manager failed to follow instructions for its care.

Interim President Ray Keck promised in August there would be changes after an internal review found a mare suffered for months with a painful condition before being euthanized.

But the federal report shows two other horses were mistreated over the summer.

A Texas A&M University spokesman says efforts are underway to prevent the mistreatment of animals at the university farm.

Noah Nelson says changes are in response to the USDA report that the university’s interim president, Ray Keck, established a “zero-tolerance policy” toward the neglect and mistreatment of animals. He also ordered a change of management at the university’s School of Agriculture’s farm.
