What is the effect on the baby's immune system once they are born? lower in the babies from the stressed mothers. Disappears afterwards: recovery. T & B-cell proliferation-indices were lower in prenatally-stressed piglets Graph: blue= size of thymus gland that produced lymphocytes: smaller in the babies from stressed mothers: anatomical changes!!
