Abstract

We used data obtained from a mastitis survey conducted by the Ministry of Agriculture, Forestry and Fisheriesto analyze the management practices currently in use at 109 tie-stall dairy farms in Hokkaido and five prefecturesin mainland Japan. Bulk milk somatic cell counts were found to be significantly lower in farms thatowned milk wagons, always conduct post-dipping, frequently checked overmilking, used rubber mats and maintaineda low moisture content in cow bedding. Farms with higher bulk milk somatic cell counts had significantlylower average annual milk yields, indicating that mastitis may result in serious economic losses for farmers.It is essential to inform farmers of proper management practices for milking hygiene to reduce somaticcell counts in bulk milk.
