| This study was carried out to compare the thermoregulatory behaviours of low and high producing dairy cows in a hot environment. Forty-one Holstein Friesian cows in their first lactation were allocated to two groups (n=21 for group 1, n=20 for group 2) on the basis of their milk production: low (<20kg) and high (>25kg). For a period of 4 weeks, and 2 days per week, the behaviour of each cow was registered every 10min for 6h (06:00–07:00h, 10:00–11:00h, 13:00–14:00h, 16:00–17:00h, 20:00–21:00h and 23:00–00:00h), recording the frequency of eating, drinking, ruminating, standing, resting and locomotion. When air temperature increased from 06:00a.m. to 16:00p.m., the frequencies of eating (31.7–17.4%) and ruminating (18.1–14.6%) decreased while standing (25.0–38.4%) and drinking (5.2–7.4%) increased in high producing dairy cow (P<0.001). However, the changes the respective frequencies for low … |
