| The demand for organic products in Europe is growing, especially organic products of animal origin. Organic dairy milk production requires grazing of cows, which results in a feed ration that is pasture-based. The breed that is kept by far the most for dairy production in Europe is the Holstein Friesian cow, a high-yielding dairy cow. This cattle breed has been developed in North America and was selected for its high milk yield. The disadvantages of this one-sided selection for production manifest in the health, fertility and longevity of the cow. More important, the high milk yield of the Holstein Friesian is only achieved when the cows are fed a diet of high quality and especially concentrates, which is not always possible in a pasture-based system.

| An experiment was conducted to test whether dietary sainfoin (Onobrychis viciifolia), a plant containing condensed tannins, affects feeding and rumination behaviour of dairy cows fed different roughage-only diets. Out of a herd of sixty lactating Swiss Fleckvieh cows, twenty-nine were chosen for a 6-week experiment. Cows were fed pasture, fresh cut grass and hay. During week 1 (baseline) and weeks 2-4, they had access to pasture for 4 hours during day, and received approximately 6 kg DM/day fresh grass and 4 kg DM/day hay in barn. In week 5 and 6, daily pasture allowance was 2 h; hay offer was doubled. In week 2-6, each cow individually received respectively 1 kg of pelleted feed in the morning and in the evening. Ten cows received ryegrass pellets in week... |
