Developmental Programming in a Beef Production System

Abstract

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 different environments may advance cowherd efficiency.
