| Organic livestock farms, at least in the northern part of Europe, are dominated by rather specialized units with production based on only one type of livestock, as dairy cows. The specialization is followed by a steady increase in size of the production unit, both in number of livestock and area belonging to the farm. In Denmark has the average organic dairy farm changed from 83 cows and 100 ha in 2000 to 136 cows and 172 ha in 2010; also production per cow has increased in this period from 6825 kg milk annually to 8100 kg in 2010. Such rather large changes over a decade often results in layout of the farm with long distance from the dairy facilities to the farm land. In organic dairy farming this is especially challenging as the dairy herd need to have... |

I mange tilfælde er svineproduktionen indrettet således, at søerne holdes på friland, mens slagtesvinene året rundt opstaldes i stalde med tilhørende udearealer, og det er for sådanne systemer, at videngrundlaget er bedst. |
