| The aim was to examine if including a range of grassland species could help to balance the diet on organic dairy farms compared with traditional mixtures. Four different grass species and four legume species were grown and harvested in mixtures with one grass and one legume for two growing seasons. The species turned out to have very individual mineral, vitamin and fiber profiles and organic matter digestibility, not influenced by year. Among the legumes red clover (Trifolium pratense) and white clover (Trifolium repens) had the highest feeding value and red clover had further a high content of Co, Cu and Zn. Lucerne (Medicago sativa) had as red clover a high growth potential in mixture but had in general a low content of macro and micro minerals with... |

| The aim was to investigate the micro-mineral profile of herbage as affected by grassland species, cutting time and seasonality and in relation to dairy cow requirements. The different grassland species were grown and harvested in mixtures with one grass and one legume for two growing seasons. The species turned out to have very individual mineral profiles, not influenced by year. Among the legumes red clover (Trifolium pratense) had high concentrations of Co, Cu and Zn, white clover (Trifolium repens) of Mn and Fe, lucerne (Medicago sativa) of Se and lotus (Lotus corniculatus) of Co, Mn, Zn and Fe. Among the grasses perennial ryegrass (Lolium perenne) generally had the highest concentrations of all the micro-minerals. Hybrid ryegrass (Lolium hybridum) had... |
