Abstract

Understanding the nutrient requirements and metabolism dynamics can be an important tool for adjusting nutritional programs to farm animals under a sanitary challenge. Therefore, this project aims to deepen the performance trial previously proposed to FAPESP (Process No. 2019/20150-3) by performing different approaches to the statistical analysis of the experiment data, interpreting, and discussing the results in collaboration with an international research group. In the project presented initially to FAPESP, we proposed to characterize the growth performance and the dynamics of metabolism of growing pigs under a sanitary challenge. For that, this project proposes an international partnership to evaluate the correlation between initial body composition (protein mass) on growth performance and blood parameters of growing pigs fed diets supplemented with Trp, Thr, and Met under a sanitary challenge (Salmonella Typhimurium inoculation + poor housing condition). If successful, the application of this technique can fill gaps in this area of study, and the results obtained can be used in future projects searching for new nutritional strategies to increase the efficiency of the use of nutrients of pigs under challenging environments. In addition, the internship period will allow the interaction of the Ph.D. student with an internationally recognized research group specialized in this area of the study and apply this knowledge to UNESP-FCAV.
