In the News


Connecticut Dairy Outlook Video Conference

Extension and Outreach Programs

  • Dairy Technology Tour: 2015. The UConn Dairy Farm Technology Tour: Robots and Beyond, was hosted by Dr. Sheila Andrew. The tour brought us through MA, VT and NH touring dairy farms that have adopted robotic milking systems, energy generation, and cow health monitoring technologies, e.g., rumination collars.
  • Coordinates the Annual Connecticut Dairy Conference
  • Mastitis/Milk Quality - Applied Research: Collaborators are an Honor’s student, professor emeritus, department compliance officer and numerous students and dairy farms.  In 2013, the research has been brought to commercial dairy farms that have mastitis concerns. We are collecting data and providing recommendations and free testing for the dairy farms. Mastitis prevalence is reducing on these farms.  
  • Dairy Cattle Nutrition: In this applied research/extension area, I have focused on the feeding value of an alternative feed, snaplage, that provides energy/starch in dairy cattle rations and can be produced on the farms, which reduces the cost of feeding the dairy herd. I have received 2 grants, and have trained a graduate student and 2 undergraduate students. I will be visiting farms in the Summer of 2013 to collect samples of snaplage and consult with dairy producers. In addition, I have consulted with approximately 12 dairy farms concerning dairy nutrition issues.
  • Dairy Farm Advisory Board: The board is meeting less frequently in 2013; however, the impact of this board is becoming more evident. In a meeting of 2 farms, the profitability of both farms has increased over the last 12 months.
  • State of Connecticut Cost of Production Study: The Connecticut State Department of Agriculture commissioned a project with the Department of Resource economics to determine a cost of production estimate for CT dairy producers. This is an essential figure because diary producers should understand their costs and this will be used by the State Dairy program for grant to dairy farmers. I assisted with data collection, summary and reporting to dairy producers.
