This market study is part of the close collaboration between Universidad Tecnológica de la Costa and the productive sector. The objective was to determine the feasibility of expanding the market of the dairy products produced by the company named Villahgo, towards the municipality of Santiago Ixcuintla Nayarit. There were applied 117 surveys to calculate the sample set at a maximum error margin of 8%, working with 92% level of confidence. Data collecting was randomly picked from the chosen neighborhoods. It was determined that most households in the city of Santiago are used to consume dairy products due to flavor and nutritional values. The fact that some percentage of people do not consume dairy products due to lactose intolerance, was also detected; therefore it was determined that the expansion of the company Villahgo is in fact feasible.Keywords: Dairy products, marketing, Santiago Ixcuintla.
