Importância da qualidade do PDI nas rações para aves

Abstract

The present work had the thematic quality in the process of the production of rations for birds taking into consideration the studies about the PDI carried out in a company in the West of Paraná that operates in the branch of Poultry. Before going into the process itself, a historical survey was made on the theorists that permeate this theme through the twentieth century by discussing the growth indices of feed production in Brazil, which justifies the need to carry out research of this kind in our country, since it does not yet have its own literature in this area. Throughout this research we deal with the historicity of control and quality, an opportunity in which we raise the historical bibliography that runs through, in a brief way. We also present the product to which our research is dedicated: the ration, in which we present SINDIRAÇÕES numbers. The parameters in the quality of feed production were discussed by explaining and presenting the specifications in the grinding, mixing and pelletizing processes, in the same way as we list the factors that influence the PDI. The work was carried out as action research, with research done through documents, quantitative approach and data collection are classified as secondary. Two-stage feed rations, 1 plant growth and 1 plant removal were performed to verify the PDI quality of the pellets in different scenarios. At the first moment, sieves with smaller drilling and times in the same mixture were used in both sen-siurs with 60 seconds of dry mix, 40 seconds of wet mixing and total mixing of 180 seconds, resulting in a more resistant pellet, at the second moment we used sieves in the thicker drilling mill which resulted in a lower strength pellet with its lower durability index.
