Heat Detection
Know when to breed
Heat Detection is one of the most valuable activities of your farm management.
Accurate heat detection is critical to the success of artificial breeding (AB). Farmers want it to be easy to correctly select animals on heat
Improvement of whole herd fertility is in your hands. The clip below explains what is happening during the 24 hours of oestrus. Combine this with knowing the signs of cow behaviour, will help you achieve more accurate detection of heats. Heat detection aids, such as Estrotect, are just that – an aid in detecting heat.
