Abstract

Three different perennial legume species (Lotus corniculatus, Medicago sativa,\ud Trifolium pratense) were cultivated in alternate drills with one of three different grasses\ud each. L. corniculatus is known to be rich in tannins, which are supposed to have\ud positive effects on protein digestion of ruminants and methane emissions. One of the\ud grass components was a Lolium perenne cultivar (cv. Aberavon) with increased\ud concentrations of water-soluble carbohydrates (wsc). The influence of this grass\ud variety on forage characteristics in mixtures was tested compared to other grasses\ud (Lolium perenne cv. Gladio and Lolium multiflorum cv. Ligrande). Dry matter yield of\ud different mixtures was determined and concentration of wsc in herbage before ensiling\ud was analysed. Digestibility of organic matter (DOM) in silages was determined\ud encymatically. Aberavon had higher contents of wsc compared to other grasses but\ud there were no differences in DOM of silages caused by the grass cultivar. Mixtures\ud containing Aberavon yielded less dry matter than other grasses. Dry matter yields of\ud mixtures with L. corniculatus were similar or slightly inferior to the yield of the mixtures\ud with M. sativa or T. pratense. Digestibility of silages including L. corniculatus was\ud similar to M. sativa variants and even superior to T. pratense mixtures in single cases
