Hops (Humulus lupulus) is a perennial fast-growing, twining, climbing plant of the Cannabaceae family. It has numerous rough, prickly stems that grow up to 20 feet in length and produces yellow to yellowish-green flowers that hang in panicles or catkins, depending on the sex of the plant. It produces scaly, pale yellow-green, cone-like fruits that are develop from the female flowers. Hops are well-known for its use in making beer. The bitter, aromatic taste of beer is mostly due to the hops content. H. lupulus contains high amounts of estrogen and numerous bioactive compounds, including lupulone, a beta-acid derived from hops. Specific applications studied in poultry include:
  • Gastrointestinal protection: Broilers fed 30 mg/kg of hops beta-acids showed a decrease in C. perfringens strains that cause necrotic enteritis in chickens.
