Central to much of the research conducted by this group is the principal that events occurring while the oocyte is developing in the ovary and during the early stages of embryo development affect the integrity of all tissues and organs of the body, contributing to the future health and performance of the animal, thereby ensuring health and optimising productivity.
Current research projects are investigating the effects of altered pre-conception and prenatal nutrition, prenatal stress and genotype on ovarian follicular fluid composition, feto-placental function and the development of key organ systems in offspring.
A major area of current research involves understanding the contribution of the uterus and the placenta to foetal growth restriction in the pig.
