摘要

Three different perennial legume species (Lotus corniculatus, Medicago sativa,udTrifolium pratense) were cultivated in alternate drills with one of three different grassesudeach. L. corniculatus is known to be rich in tannins, which are supposed to haveudpositive effects on protein digestion of ruminants and methane emissions. One of theudgrass components was a Lolium perenne cultivar (cv. Aberavon) with increasedudconcentrations of water-soluble carbohydrates (wsc). The influence of this grassudvariety on forage characteristics in mixtures was tested compared to other grassesud(Lolium perenne cv. Gladio and Lolium multiflorum cv. Ligrande). Dry matter yield ofuddifferent mixtures was determined and concentration of wsc in herbage before ensilingudwas analysed. Digestibility of organic matter (DOM) in silages was determinedudencymatically. Aberavon had higher contents of wsc compared to other grasses butudthere were no differences in DOM of silages caused by the grass cultivar. Mixturesudcontaining Aberavon yielded less dry matter than other grasses. Dry matter yields ofudmixtures with L. corniculatus were similar or slightly inferior to the yield of the mixturesudwith M. sativa or T. pratense. Digestibility of silages including L. corniculatus wasudsimilar to M. sativa variants and even superior to T. pratense mixtures in single cases.
