More legislation pending in the general assembly would make it illegal for horses to be slaughtered in the state, or to be transported elsewhere to be cut for food.
State Sen. Tom Buford of Nicholasville, Ky., said it will not be tolerated in the quote "horse capitol of the world" end-quote.
Buford also said he decided to take up the fight after a similar initiative failed in Washington last year.
Advocates for protecting horses are heralding the move in Kentucky where there are an estimated 320,000 horses. Defenders of horse slaughter say it offers a cheap and humane way to end a horse's life when the animal is no longer useful. They also say many owners can't afford to care for an unproductive horse.
