Good heat detection is essential

  

This routine generally yields good oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals. detection rates of around 60 to 70%. High producing herds may require more frequent observations or most likely associate the use of synchronization programs and oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals. observations to keep oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals. detection rates above 60%.

Automated electronic oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals. detection devices are also a good option for some herds.

Heat detection in dairy herds

Cows producing more milk tend to stay less time showing behavioural oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals.. For example, the graph below shows that cows producing less than 30 kg of milk/day can be detected accepting mounts (main oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals. sign) for roughly 15 h. In contrast, high producing cows averaging more than 40 kg/day stay in oestrusAlso known as heat, is the physiological and behavioral phenomena which precedes and accompanies ovulation in female mammals. for only 5 h. or less!
