This research proposal focuses on optimizing the use of nitrogen (N) resources to ensure the sustainable development of swine productions that currently face significant environmental, economic and societal challenges. The general objective is to reduce N excretion by optimizing its use by animals, by adjusting, as accurately as possible, the contribution to the needs of the animals to avoid reducing performance. This will in turn reduce the release of N into the environment. Research project will focus on both piglets and growing pigs that face the same issues. The achievement of these objectives will be done through the training of a MSc, an undergraduate and a post-doctoral student. Two objectives will be developed 1) Estimation of piglet response to valine and impact of the other branched-chain amino acids (BCAA), leucine and isoleucine, on this response through a meta-analysis approach and 2) giving the few data available in growing pigs, an in vivo trial on the response of growing pigs to dietary valine.

该研究建议着重于优化使用氮（N）资源的使用，以确保猪的可持续发展目前面临着巨大的环境，经济和社会挑战。总体目标是通过尽可能准确地调整动物的贡献来避免降低性能，从而减少n个排泄。反过来，这将减少N释放到环境中。研究项目将重点放在仔猪和面临相同问题的猪的成长上。这些目标的实现将通过培训MSC，本科生和博士后学生来实现。将制定两个目标1）对门仔的反应估计以及其他分支链氨基酸（BCAA），亮氨酸和异亮氨酸的影响，通过荟萃分析方法和2）提供了少数数据，可提供少数数据。猪，一项关于生长猪对饮食瓣膜的反应的体内试验。
