The demand for food destined for animal nutrition has increased over the years, causing industries to increasingly invest in production processes. To improve process efficiency, Kaizen is a viable tool for the implementation of continuous improvements. In this sense, this study aimed to implant Kaizen in an animal nutrition industry to obtain several improvements in the production process of this company. The research method consisted of a case study with application of the steps proposed by the Kaizen tool, which started with the definition of the value flow map and followed with action plans for the proposed improvements. Among the results, ten enhancement measures were implemented in the different sectors of the company, which allowed an improvement in the production of products for animal nutrition. The practical implication is the method of applying Kaizen as a tool for continuous improvement with the help of the value flow map in a food company.
