Domestic pigs (Sus scrofa domesticus) face a range of environmental challenges throughout their life course, and there is considerable variability between pigs in how well they cope with these challenges. The microbiome and the subsequent growth and development of offspring are shaped by the conditions experienced during pregnancy, the location and mode of delivery and the diet of an individual. Given that sows may be located either indoors or outdoors with different farrowing conditions and piglet feeding systems, a piglet's microbiome and development could be heavily influenced by the environment in which it is born, and could affect an individual's ability to cope with environmental challenges, ultimately compromising performance and health. The gut microbiome and its associations with pre- and neo-natal diet and subsequent impacts on performance, health and cognitive development is an area of emerging and increasing interest to both academics and the pig and animal nutrition sectors with substantial potential real-world impact. The overall aim of this project is to investigate the impacts of different dietary constituents in the pre-and neo-natal stages of development, and early life environment on cognitive development, welfare and performance, using pigs as a model system.

家猪（Sus scrofa Domesticus）在其整个生命过程中面临着一系列环境挑战，而且猪之间应对这些挑战的能力存在很大差异。微生物组以及后代的生长和发育是由怀孕期间经历的条件、分娩地点和方式以及个人饮食决定的。鉴于母猪可能位于室内或室外，具有不同的分娩条件和仔猪饲喂系统，仔猪的微生物组和发育可能会受到其出生环境的严重影响，并可能影响个体应对环境挑战的能力，最终损害生产性能和健康。肠道微生物组及其与产前和新生儿饮食的关联以及随后对生产性能、健康和认知发展的影响是学术界以及猪和动物营养部门日益关注的一个新兴领域，具有巨大的潜在现实世界影响。该项目的总体目标是以猪为模型系统，研究不同膳食成分在产前和新生儿发育阶段以及早期生活环境对认知发展、福利和表现的影响。
