NNYADP Dairy Research: Follow Protocols to Keep Calves Healthy

Dairy calf health research funded by the farmer-driven Northern New York Agricultural Development Program and conducted by Cornell University Cooperative Extension dairy specialists demonstrates the value of keeping good calf health records and following proper calf management and, when needed, treatment protocols.

In 2018, Cornell Regional Dairy Specialist Kimberley Morrill, Ph.D., worked with eight dairy farms in Northern New York to analyze dairy calf treatment protocol impact on calf health and costs.

With assistance from Cornell PRO-DAIRY Dairy Herd Health and Management Specialist Robert Lynch, Morrill collected and analyzed more than 6,200 on-farm treatment records for non-lactating dairy heifers from birth to calving on eight Northern New York dairy farms.

The data analysis included age and treatment by illness, treatment frequency, farm compliance with established protocols, and standardized drug cost per animal per event and in total for the eight-month study period from January 1 to August 31, 2018. Written on-farm protocols were followed to treat 91.64 percent of the illnesses over the eight-month period.

“Following best management practices that have been developed with the herd veterinarian and other consultants to prevent and reduce calf health issues from ear infections to respiratory illness early in life positively impacts calf growth, future milk production, and farm costs. This type of research supports opportunities to enhance animal welfare, farm efficiency and consumer confidence in dairy products,” said Morrill.

This research builds on previous projects evaluating the impact of environmental conditions, housing, ventilation and climate stress on calves on Northern New York dairy farms. Learn more on the Northern New York Agricultural Development Program website at www.nnyagdev.org.

An abstract of this research project has been submitted for consideration for presentation at the June 2019 meeting of the American Dairy Science Association (ADSA). ADSA featured Morrill’s NNYADP dairy research focused on reducing calf respiratory illness at its 2018 annual meeting.

Funding for the Funding for the Northern New York Agricultural Development Program is supported by the New York State Senate and administered by the New York State Department of Agriculture and Markets.
