In beef cattle, the hierarchy for nutrient use of an individual animal is first body maintenance, followed by body development, growth, lactation, reproduction and then fattening. If a situation occurs where nutrients are limited, those items lowest within this hierarchy are the first to suffer. In this presentation, Dr. Francis L. Fluharty, Ohio State University Professor Emeritus in the Department of Animal Sciences and presently Department Head at the University of Georgia Animal and Dairy Science Department, details the implications for reproductive performance, fetal development, and calf performance if nutrients are inadequate.
