Interpretive Summary: Developmental programming is the biological process by which environmental factors influence the development of the organs and tissues in the body. There are two areas of developmental programming being investigated with applicability to beef production systems to improve performance of replacement heifers. Fetal programming encompasses the area of developmental programming that influences the quality of the gametes or the development of the embryo/fetus and impacts performance of the progeny of the target individual. Nutritional programming encompasses the area of developmental programming that directly influences the individual during the first year of life and impacts their subsequent performance. While there are other environmental triggers that stimulate developmental programming, most researchers believe that nutritional interventions are the ones that will be most readily adaptable to beef production systems to improve performance of replacement heifers.
