Hops & Organic Chickens
Northwest Crop Could Replace Poultry Antibiotics
YAKIMA, Wash. -- Hops give beer flavor. They also inhibit unwanted bacteria growth.
Now, researchers say they may do the same in chickens.
HopsUniversity of Arkansas researchers have found that hops show promise as a stand-in for antibiotics to promote poultry growth.
The demand for more natural chickens has grown dramatically in the past couple of years. So has the demand for cage-free chickens and eggs from cage-free chickens.
Most commercial chickens are kept in tiny cages until they reach nearly full size, then they're slaughtered for food. Egg-layers are also kept in cages, and often filled with hormones and antibiotics to increase production and prevent disease.
Now, the researchers say hops may be an organic replacement for those antibiotics, especially in broiler checks.
The Arkansas researchers workd with a hops chemists and growers in Eastern Washington state.
Their research indicates that adding ground hops to feed can boost growth without antibiotics. Organic chicken farmers are already expressing interest, as are hops growers. Hops are a major commercial crop in Oregon's Willamette Valley.
