No bull, the Food and Drug Administration approved a drug on Tuesday that aims to make cattle manure just a little less aromatic, NBC News reported.
The drug, called Experior, is designed to reduce the amount of ammonia released by cattle dung when the animals are in feedlots being fattened for slaughter.
"Today’s approval is the first time the agency has approved a drug that reduces gas emissions from an animal or its waste," the FDA said.
The goal is to make a little less of a stink, the FDA said. "Ammonia gas emissions are a concern because they have been implicated in atmospheric haze and noxious odors. High concentrations of ammonia can cause irritation of the eyes, nose and throat in both humans and animals," the agency said.
