Milkrite, a division of Avon Rubber and Plastics, works on products for the agriculture industry and is based out of Wisconsin and California. Milkrite is the world’s largest provider of dairy rubber wear, with their core business focused on creating rubber liners which are used in the milking machine. We reached out to Tom Votny, a representative of Milkrite. During our conversation, we learned about the current state of the milking machine market, what technologies had already been developed for shell and liners, how products were typically tested, and how large companies conducted their market research. The insight we gained helped the product development further understand that the direction they are going with the milking shell is feasible, but simultaneously allowed them to find out what other components of the milking machine they would have to consider. We also learned that farmer feedback is essential to making sure that our project as a whole would do well in the market. As a result, we launched into contacting as many farms as we could to garner that feedback.

At this point, it had been nearly two months since our last visit with Daryl Nydam of Quality Milk Production Services. He had given us a plethora of valuable information while we were still in the beginning stages of the project, so we chose to go back and talk to him again once our ideas were more fleshed out. We talked to him about the progress of our bacteriocin research, and Dr. Nydam lent us a field guide for mastitis that gave us a solid foundation of how we should move forward with bacteriocin testing. He also agreed to provide us with infected milk samples that we could use as test targets, and genomic preps of Lactococcus lactis and Bacillus subtilis, two promising bacteriocins that required genes too large to synthesize. We then spoke to Dr. Nydam about the milking shell that we were developing for the milking machine to aid in the prevention of the disease. He particularly liked the iodine spray, UV light, and cold shock modules. He thought the idea of the cold shock was extremely innovative, but suggested that we talk to more experts to discover if physiologically it would work. No research seems to have been done on the temperature that would be required to achieve the cold shock. We also spoke to Dr. Nydam about our ideas for the app we are going to give to farmers. He referred us to research articles he had read that would help us with the economic analysis of treating or culling a cow. He told us to refer to the published scientific literature for the most accurate descriptions to be used for CowMD, but that the symptoms for each type of mastitis often blur together so a search engine taking inputs of symptoms would not be useful. In addition, he was fascinated by the somatic cell counter and urged us to further pursue that option. While there are tests like the California Mastitis Test that already allow farmers to quickly detect mastitis, this new innovation could change the way the disease is approached and dealt with by farmers. Dr. Nydam praised us for choosing a project in the dairy industry because of the strong agricultural presence in New York, along with the connections that Cornell has. Overall, Dr. Nydam emphasized something that everyone we have met has said: farmers want ease and effectiveness. Throughout the rest of the creation process, we kept that in mind through the rest of our project.

We were thrilled to schedule our next farm visit to Scipio Springs Dairy in Scipio Center, NY because it was very different from the previous two farms that we had visited. Scipio Springs Dairy is a much larger farm with 800 cows and is set up like a traditional milking parlor, with 12 cows in parallel with one another. We met with Bill Morgan, who looks over the operations of the dairy farm, and the herd manager of the farm, allowing us to get a more well-rounded feedback on our wet lab, product development, and app components of our project. Bill was extremely interested in implementing bacteriocins on his farm instead of using traditional antibiotics. He was impressed by our modular idea for the shell because he believed that it was an all-encompassing prevention to mastitis. Bill believed that the UV light would be a great alternative to the traditional use of heat because heat changes the functionality of the proteins in the milk as well as the milk’s flavor. He also liked the idea of the temperature sensor because gram negative bacteria mastitis typically causes an increase in temperature. Using a temperature sensor would be better than the conventional way of finding out that the mastitis is caused by gram negative bacteria visually because by the time the cause is found, the damage to the cow and its milk is already done. Overall, Bill Morgan was supportive of our idea, and was interested in trying out our prototype and app once we finalized them.
