This study was conducted to validate the relationship between environmental temperature during feeding period and performance indices in commercial poultry farms in Korea. A total of 406 performance data were used to analyze and the data were provided from the commercial farms which belong to the integrated broiler company in Korea. The data were collected from August 2013 to November 2014. The environmental temperature used in this study was an average temperature of Chungcheong-do in Korea where the commercial farms located. The average environmental temperature negatively correlated (p<0.05) with all performance indices except the ADG, medicine cost and total income. There were positive correlations (p<0.05) in medicine cost and total income per gain (won/kg/d) with the average environmental temperature. In conclusion, the higher environmental temperature reduced the ADFI, feed cost and total cost but increased total income in the commercial broiler farms in Korea.
