Grazing management for Nordic organic dairy farming

A grazed field experiment based on a randomised block design was conducted in Eastern Finland to evaluate the potential of alsike clover (Trifoliun hybridum L.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) to support herbage production from clover-grass mixtures under organic farming practices. The effect of seed mixture (alsike clover, red clover, white clover, white and alsike clover or grass mixture), year (1996, 1997 and 1998) and grazing period (5 per grazing season) on pre- and post-grazing herbage mass (HM), botanical and chemical composition of pregrazing HM and post-grazing sward height was assessed. The nutritive value of herbage for milk production was also considered. Seed mixtures resulted in different pre-grazing...

The aims of this study were to identify limiting factors and to develop adjusted grazing management for Nordic organic dairy farming conditions. The focus was to combine the aspects of plant, animal and organic production, as they are all involved in organic dairy pastures.

In conclusions, certified organic milk from organic farms had favorable omega FA composition than milk from farms practicing only organic field farming and giving more concentrates. Relatively high milk ALA proportions suggested positive effect of red clover in both farm groups.

Annual pastures, seed mixtures and supplementary feeding in organic milk production

A grazed field experiment was established in 1995 to evaluate alsike clover (Trifoliun hybridum L.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) in clover-grass mixtures under organic farming practices. In this study the effect of seed mixture (alsike clover, red clover, white clover, white and alsike clover or grass mixture), year (1997, 1998) and grazing period (5 per grazing season) on the herbage calcium (Ca), magnesium (Mg), potassium (K) phosphorous (P) and sodium (Na) contents was assessed and the relationships between botanical proportions and herbage mineral contents were studied. Herbage Ca and Na contents varied between the seed mixtures, Ca, Mg, P and Na contents between the years and all measured minerals, except...

The current study was aiming to evaluate annual legume-grass-cereal mixture as a basal feed for dairy cows under organic or other low fertiliser input systems in Nordic conditions. In additional aim was to evaluate the effect of concentrate feeding regimen in order to simplify grazing management.

White clover suited best for cow grazing under organic farming conditions in Middle Finland. However, the clover proportion of all clover mixtures decreased from year to year and varied within grazing season.
