These play a critical role in programming for its future environment available resources. Fetal reportedly affects neonatal mortality morbidity, postnatal growth rate, body composition, health, reproduction. Two mechanisms responsible fetal DNA methylation histone modifications. Alterations genome can be passed through multiple generations. Maternal (nutrition, age, physiologic status) program progeny heifer reproductive performance.
