Resumo: | Determination of animal profile from production scenarios by modeling is essential to improve production. The objective of this study was to model and evaluate the performance, the supply and nutrients requirements for pigs, during the growing and finishing phases, in real production scenarios. Six scenarios with 2,200 animals, which consumed six ad libitum diets, were selected. The collected data from the production scenarios were modeled based on the average animal. Animals were housed at 65±7 days old and weighing 22.11±1.41kg and were slaughtered at 159±10 days old and weighing 121.18±7kg. Average of the scenarios was greater than 0.27kg for consumption and 0.12kg for weight gain; feed conversion was equivalent to the standard animal profile (SAP). Scenarios were 1.60g higher for the requirement and 2.67g higher for daily digestible lysine per animal when compared to the SAP. Production scenarios showed differences between performance, supply and nutrient requirements for pigs during the growing and finishing phases. Modeling is a tool that can be used to describe and compare the characteristics of each production scenario.
