Developmental Programming and Growth of Livestock Tissues for Meat Production
Maternal regulation of fetal development has consequences for growth and development of carcass tissues. Severely restricted fetal growth can reduce postnatal growth capacity, resulting in smaller-for-age animals that take longer to reach market weights but has little effect on feedlot efficiency or carcass and meat quality. Specific nutritional supplementation, particularly during later pregnancy, may limit fetal growth retardation and enhance postnatal growth capacity and carcass characteristics, and may improve development of intramuscular fat. Continued improvements in understanding developmental processes and their re...

Multigenerational Effects
Environmental influences resulting in epigenetic mediation of gene expression can affect multiple generations via direct effect (first generation); direct or maternally mediated effects on the fetus (second generation), or gonadal cell lines of the fetus (third generation) when pregnant animals are exposed to the stimuli; and through generational inheritance. The cumulative effects are rapid changes in phenotypic characteristics of the population when compared with rate of phenotypic change from genetic selection. With extensive data collection, significant potential exists to propagate desired characteristics in the lives...

Developmental Resiliency
Stimuli experienced in utero can have a lasting impact on livestock growth, reproduction, and performance. Variations in environment, production system, and management strategies lead to discrepancies in the literature regarding how specific treatments influence animal performance. Studies comparing the influence of maternal undernutrition to well-fed counterparts typically result in decreased productivity of offspring. Via adaptation to nutritional or environmental stressors, dams may develop mechanisms to ensure proper nutrient supply to the fetus. It appears nutrient deprivation must be severe for consistent results. Po...

Developmental Programming in a Beef Production System
Beef production is a complex system, in which cows are expected to perform in varied environmental conditions. In cattle, the most commonly reported developmental programming influence is nutrient restriction during the prenatal period due to climatic conditions affecting forage availability and quality. Recent research has demonstrated maternal or prepartum nutrition can affect more than just subsequent pregnancy rates. Studies in different species report how maternal nutrition influences progeny performance, health, and reproduction. Better understanding of developmental programming and nutritional management within diff...

Developmental Programming in Livestock Production
The concept of fetal programming, also known as developmental programming, was first hypothesized using human epidemiologic data, where environmental stimulus in utero resulted in long-term development changes in growth and disease susceptibility in children from undernourished mothers during the Dutch famine. This concept is important due to the impact that maternal stimulus or insult at a critical period in fetal development has long-term effects on the offspring. While maternal nutrient delivery during pregnancy has been shown to program the growth and development of the fetus, both during pregnancy and later into adult...
