The complex process of transformation of poultry industry in the Zulia region of Venezuela and the amplitude of this value chain require determining management policies oriented to management of stocks (inventories), as a key element to ensure continuity on its operations. In this sense, the aim of this paper is to analyze the inventory management in the poultry company La Rosita S.A. (AVIROSA) case. Thus, first of all, the authors identified all the types of inventory used by the organization; and, afterwards, the policies implemented for planning and control of these assets were studied. A descriptive methodology under a non-experimental approach was used, based on secondary sources and also primary data collection; this latter were obtained through a questionnaire in the form of surveys, as well as in-depth interviews with key people working inside the organization. Main results indicate that the company uses raw materials, work-in-process and finished goods inventories in various stages of the value chain; moreover, planning policies and control to this area are flexible and defined in terms of two factors: 1) internal changes made in the production process, and 2) external requirements demanded by the market. It concludes that an irregular management of inventories of raw materials, work-in-process and finished goods has been applied during the supply chain; additionally, the inventory policies are not accurately systematized for compliance; instead, these policies are determined by personal experience in the poultry industry.
