Oestrus detection in dairy cows by milk temperature measurement

Abstract
The efficiency of oestrus detection is probably the most important factor determining the profitability of the dairy farming enterprise. With current trends towards larqer herds and fewer stockmen, achieving a 365 day calving interval has become increasingly difficult, with each oestrus missed representing considerable economic loss (Esslemont and Bryant, 1976). This highlights the need for an accurate method of oestrus detectionAn experiment was undertaken to evaluate the use of milk temperature as a method of oestrus detection.
