How does a reduction of 27 seconds add up to a gain of an important 15 minutes and more comfortable dairy cows?
Research funded by the farmer-driven Northern New York Agricultural Development Program and conducted by Quality Milk Production Services and Cornell Cooperative Extension showed nearly two dozen dairy farms just how.
Paul D. Virkler, D.V.M., a veterinarian with the Quality Milk Production Services Animal Health Diagnostic Center, Canton, N.Y., led the project that influenced a simple, but significant, change in the milking parlor settings on 23 farms milking cows two to three times a day in Clinton, Franklin, Jefferson, Lewis or St. Lawrence County.
The project demonstrated how adjusting the setting on the automatic cluster remover, or ACR, unit that controls when the milking unit detaches from the cow based on a decrease in milk flow reduces milking time with benefits to the farmer, the cows, and the farm business.
From the cow’s perspective, taking the milking unit off more quickly by adjusting the ACR alleviates the potential of overmilking and related impact on teat tissue condition, thus making the cow more comfortable, reducing the risk of mastitis, and enhancing animal well-being.
For the farm business, Virkler noted that “Although milking time is significantly shorter, earlier research, and this trial, has shown there is no negative effect on or loss of milk yield.”
Following the main trial at Hillcrest Holsteins in Henderson, N.Y., the project team extended the research results to 22 additional farms, with a change in the ACR setting recommended to 20 of those farms. All twenty made the change with positive results.
