In the thesis, we make a review of the literature related to organic milk production and analysis of organic milk production of two Slovenian organic dairy farms, which are oriented towards the production of organic milk. In the review of literature, we tried to obtain the most recent findings, which has related to the production of organic milk in Slovenia and in the world, and what is the organic milk price in some countries of the European Union. We also mentioned differences between the organic and conventional way of milk production and differences in quality of organic milk compared to conventional milk. In the analysis, we included two Slovenian organic dairy farms that are rearing dairy cows and selling organic milk on the market. In 1999, these two farms decided for the transition to organic farming. Family farm Meden breeds Brown Swiss cows, while in the farm Kocjančič they rear Holstein-Friesian cows and crossbreeds. We examined the production of organic milk for these two farms in the period 2010 - 2017. On both farms, there are still many opportunities for improvement, which could improve production results on both farms. On the farms, they could better use grasslands (attaining grass, application of organic mineral fertilizes, …), which could consequently also lead to better quality of forage and higher milk yields on farms. They could reduce income losses by lowering the heifer age at first calving, shortening the calving interval and days open.
