The aim of this project is to study the variability problem of animal response when establishing nutritional programs (pigs) and the application of the concept of the feeding precision (pigs and poultry) using integrated management systems. For this purpose, three studies will be carried out. In the first two studies, the optimal methionine and threonine level for a pig population based on feed intake and growth changes for each individual in real time will be estimated. A completely randomized design with six treatments (six different levels of standardized ileal digestible methionine or threonine) will be used. In the last study, nutritional programs defined by modeling and applied in different feed systems (daily and individual or feed phases and animal group) for growth pigs will be evaluated. Six treatments in a factorial design 2x3 will be used [Feed Program (FP) with animal group and three feed phases or FP with individual and daily phases; three weight groups: light, medium and heavyweight. In both studies the Intelligent Precision Feeder will be used. The last study refers to evaluating nutritional programs establishedby modeling and applied in different feeding systems (four phase vs. multiphase) for chickens. Four treatments will be used in a factorial design 2x2 (Ad libitun feed intake or controlled feed intake; FP with four phases or multiphase). Through of the development of these studies it will be possible to begin the implementation of a new line of research in this unit faculty. Additionally, this project can effectively contribute to the reduction of the environmental load of growing and finishing farms, while ensuring their economic viability. (AU)
