This study was conducted to investigate feeding management and milk production in domestic organic dairy farms and find out ways to overcome difficulties in organic dairy farms. The number of domestic organic dairy farms was 35, which representing 0.57% among 6,068 of total dairy farms in 2011. Eleven farms among 35 organic dairy farms were surveyed. Average total raising head was 142, composed of 69 milk cow, 13 dry cow and 60 heifer and calf. The ratio of cow replacement was 42.4% in surveyed organic dairy farms. Among surveyed farms, 14.3% showed under 20kg of milk production, 57.1% represented 25~30kg of milk and 28.5% produced more than 30kg of milk. Average milk fat percentage in surveyed organic farms was 3.3%, which was lower than 4.04% milk fat percentage of whole country (2010). Based on bacterial counts (5,775 CFU/ml) and somatic cell counts (192,500 number/ml), milk quality appeared excellent in surveyed farms. 90% of surveyed farms agreed that organic milk production increased income. Among reasons for switching to organic dairy farm, environment-friendly farm management was the highest reason (54.5%). However, 45.5% of surveyed farms suffered difficulty in supply of organic feed. Therefore, stable supply of organic feed will be necessary to expand organic dairy farm in the future.
