Özet:

In Turkey, roughages are insufficient to meet the quality roughage needed by the existing livestock population. For this reason, alternative roughage sources should be included in the rations. Some plants are important in terms of rumen health and animal productivity with contain the secondary metabolites (phenolic, flavonoid, condensed tannin, etc.). While these metabolites control nutritional stresses, such as rumen fermentation, bloating and acidosis, they can also be used as natural antibiotics. The hop (Humulus lupulus L.) is known as "beer flower" among the people and is a perennial herbaceous plant with a climbing stem from the cannabis family. The unused parts of hops such as stems and leaves are more than the parts used in beer production. The plant contains a significant amount of polyphenols, crude protein and crude ash, it has a high digestibility. Besides, hop has condensed tannin, therefore, it inhibits ammonia production and contributes to the reduction of greenhouse gas emissions. In this review, it is aimed to give information about the evaluation of hops as a fodder crops and to contribute to the national literature.
