Transitioning from conventional to automatic milking: Effects on the human-animal relationship

Area of Science:

• Animal behavior and welfare
• Agricultural technology
• Dairy science

Background:

• Conventional milking systems (CMS) and automatic milking systems (AMS) differ in management, but their impact on the human-animal relationship is underexplored.
• Understanding these differences is crucial for animal welfare in modern dairy farming.

Purpose of the Study:

• To investigate the effect of transitioning from CMS to AMS on farmer-cow interactions and cow behavior.
• To assess changes in cow fearfulness and stress responses post-AMS implementation.

Main Methods:

• A survey and observational study on 5 Australian dairy farms during their transition from CMS to AMS.
• Data collection included farmer surveys, documentation of farmer-cow interactions, measurement of cow avoidance distances, and a handling test before and after AMS transition.

Main Results:

• Farmer-cow interaction time decreased on 4 out of 5 farms after AMS transition due to reduced milking tasks.
• Cows exhibited a significant decline (approx. 27%) in avoidance distances from humans in AMS environments.
• Handling tests showed cows required more vocal effort but displayed reduced running and slipping, indicating less fear and stress.

Conclusions:

• While AMS reduces direct farmer-cow interaction time, it leads to less fearful and less stressed cows.
• The transition to AMS positively impacts the human-animal relationship by reducing cow fearfulness around people.
• AMS technology can contribute to improved animal welfare on dairy farms.
