Kentucky Governor Steve Beshear is using his executive authority to implement a regulation allowing only government veterinarians to administer race-day drugs to horses. Thursday’s action comes days after the proposed regulation appeared stymied by objections from state lawmakers. Beshear says it's in the racing industry's interest to let the rule take effect. Republican State Senator Damon Thayer praised the governor’s action. He says it sends the message that Kentucky will be at the forefront of efforts to change perceptions about the use of drugs in horse racing. The regulation would also set lower amounts of some medications given to horses within days before a race.
