Abstract :This study evaluated the effects of different luminance levels on behavior, feed intake, body weight and blood properties of Japanese black cow in a cattle farm. Six cows which delivered caves two months ago or will deliver calves two months latter ware taken in this experiment. The cows were evaluated in low luminance environment (270 Lux) and control environment (9931 Lux) for 11 days, and the evaluation was repeated three times. Cut roughage was provided as ad libitum feeding and concentrated feed of 1 kg/day was added as supplement. The cows in the low luminance environment showed lower tendency in aggression, threatening and escaping behavior than the cows in control environment. Dry roughage intake, body weight and blood properties were not significantly different between the cows in the low luminance environment and control environment. This study indicates that group feeding of cow in low luminance environment is a possible method to decrease fighting behavior.
