Abstract

This project aims to continue the study (JP1) of the factors responsible for the variability of pig performance and thus establish nutritional programs based on the concept of precision nutrition. The health status of animals associated with management practices and ambient temperature has been considered one of the main factors that contribute to this variation. Therefore, the objectives of the project are: a/ to evaluate the effect of different sanitary housing conditions on the on the physiology, metabolism, health status and performance of post weaning piglets; b/ to evaluate the interaction effects of nutritional strategy, health status, sanitary housing conditions and ambient temperature on the physiology, metabolism and performance of growing-finishing pigs; c/ to develop a method to monitor the health status of pigs in real time. For that purpose, the project is divided into 4 phases. In Phase 1, a survey of the management practices adopted during the post- weaning and growing-finishing phase in Brazilian pig farms will be conducted. In Phase 2, a systematic study (meta-analyses) will be performed to qualify and quantify the optimal amino acids levels to be used in the diets according to the different challenges which pigs can be exposed during the growing-finishing phases (sanitary conditions and ambient temperature). In Phase 3 a study will be conduct to evaluate the effect of different sanitary housing conditions on the on the physiology, metabolism, health status and performance of post weaning piglets. In this phase, five others studies will be conduct to evaluate the effects of nutritional strategies (amino acids), health status (pigs from weaning phase raised on different sanitary housing conditions), sanitary housing conditions and temperature on growing-finishing pigs on physiology, metabolism and performance. In Phase 4, based on the results of Phase 3, will be evaluated the effects of nutritional strategies, sanitary status, sanitary housing conditions and ambient temperature on feeding behavior responses of growing-finishing pigs. Finally, a dynamic linear model developed to identify deviations from the normal pattern of pig feed consumption will be validated in this project. (AU)
