The results showed that the mean milk yield and mean ruminating time decreased as the temperature humidity index (THI) increased. For the ruminating time, the variance increased, and the distribution changed into bimodal one from unimodal one in the heat period. When cows were assumed to be heat-sensitive or heat-resistant based on the mean ruminating time immediately before the heat period, the ruminating time and its reduction were shorter and larger respectively in the heatsensitive cows (405.7 ± 51.7 minutes/day and –25.0 ± 47.6 minutes/day respectively) compared to the heat-resistant cows (537.1 ± 43.5 minutes/day and –11.7 ± 39.6 minutes/day respectively, p \u003c 0.01).
