The concept of fetal programming is based on the idea that nutritional status and environmental conditions encountered by the dam during pregnancy can have lifetime impacts on her offspring.  These changes in the gestational environment have been shown to influence fetal development and subsequent growth performance, carcass composition, and meat quality characteristics. Beef fetuses can be particularly prone to experiencing variations in the maternal environment during development due to a relatively long duration of pregnancy that can expose the dam to environmental temperature stress and seasonal conditions that compromise feed quality or quantity.  If feed is limited or forage conditions are poor a maternal deficiency in protein and/or energy can occur as well as fluctuations in body condition of the dam.  As a result, the fetus may receive inadequate levels of nutrients, potentially altering fetal development.  There are critical windows of development during each stage of gestation in which various tissues, organs and metabolic systems may be impacted.  Skeletal muscle and adipose tissue are particularly vulnerable to alterations in the gestational environment due to their low priority for nutrients relative to vital organs and systems during development.  The timing and severity of the environmental event or stressor as well as the ability of the dam to buffer negative effects to the fetus will dictate the developmental response.  Much of the current research is focused on the influence of specific nutrients and timing of nutritional treatments on offspring carcass composition and meat quality, with the goal of informing strategies that will ultimately allow for the use of maternal nutritional management as a tool to optimize performance and meat quality of offspring.
