Critics of horse slaughter asked a lawmaker on Wednesday to give a bill a hearing that could lead to up or down votes on the facilities.
Last year, lawmakers passed and Gov. Mary Fallin signed a measure to lift the state ban on horse slaughtering. However, federal funding for inspections has not been forthcoming, essentially putting such facilities on hold.
The law bans the consumption of horse meat in the state.
Supporters said the measure was necessary to deal with abandoned or abused animals and allow owners the option for disposing of the animals.
