Dairy Farm Business Summary and Analysis (DFBS) projects are an integral part of Cornell Cooperative Extension's agricultural education program in New York State. The Charles H. Dyson School of Applied Economics and Management of the Cornell S.C. Johnson College of Business, The College of Agriculture and Life Sciences at Cornell University, PRO-DAIRY, and County and Regional Extension staff cooperate in sponsoring DFBS projects. In 2017, over 200 dairy farms participated, including dairy owners, renters, full-time, part-time, organic, and out-of-state farms. Business records submitted by dairy farmers from 36 New York counties provide the basis for continuing Extension programs, data for applied studies, and for use in the classroom. Regardless of the use of the data, confidentiality of individual farm data is maintained.
