Abstract

This survey was conducted to give the basic information and temperature and humidity variation by cooling systems in dairy farms in Korea. A total of 36 farms were surveyed in Gyeonggi province with the general information of farms such as milk production, and milk quality, types of cooling systems, and its operation method of dairy farms. All of surveyed farms have cooling fan and some have 1 more cooling systems such as sprinkler, foggy systems, ventilation duct, and shower system. Although the indoor THI of cow house was decreased by either ventilation duct or foggy system during hot season, the range belongs to mild heat stress scale for dairy cows.
