Cornell CALS PRO-DAIRY hosts annual Dairy Discovery Workshop for youth

Youth participants used all of their senses during a sensory evaluation of dairy products, where they learned about sensory science, classic defects and the causes of off-flavors in milk. Later, they took part in dissections of udders donated from the local slaughterhouse to gain a better understanding of the anatomy and physiology of the udder and milk veins. A 90-100 day uterine calf also allowed the youth to study anatomy beyond textbook images. Among the hands-on events, they practiced administering antibiotics through the teats of the donated udders and using teat sealant equipment. 

“Seeing new, more efficient ways of doing things helps participants develop ideas they can bring back and apply to their own farms,” said Josiah Freier, a youth participant. He added that his most memorable experience of the weekend was when he ensured that the teat sealant was correctly administered by cutting off a teat to look inside the milk vein.

 Throughout the day, program participants were also transported to the Cornell Teaching Barn, to apply classroom lessons to real-life situations on the operating farm. Rick Watters, AgroChem USA senior animal health advisor, met students at the barn and taught them the details of preventing mastitis with milking, primarily through the proper use of milking machine equipment.

Participants learned that milking equipment accounts for 20% or less of mastitis cases. However, milking equipment can create induced mastitis, which is preventable through correct milking time periods and properly functioning equipment. Watters also explained that the teat canal generally remains open for 30-60 minutes after milking. But if the teat becomes congested from overmilking, it can remain open for one to six hours, significantly increasing the risk of mastitis and sickness in cows.

In addition, participants explored the science behind milk quality and the pathogens that affect herd health through identification and treatment workshops focused on mastitis. They learned that decision-making was a crucial skill, as not all mastitis cases require the same treatment approach. Severity, bacteria type, cow history and stage of lactation all factor into the level of treatment and intervention needed.

In the end, participants were exposed to dairy concepts in a new way and gained shared experiences while practicing hands-on learning. They had the opportunity to learn from experts in the field and on campus.  “Technology within the dairy industry is constantly evolving,” said Grusenmyer. “So there’s always something new to learn.” 

Applications for the Dairy Discovery Workshop will open in January every year and remain open until the program is capped or the March deadline occurs, whichever comes first. Learn more about the program.
