Feeding rates are estimates, and other factors, such as animal health and environment, can have a greater impact on how animals perform. There is no guarantee that animals will perform as expected if fed the suggested rates. Rations should be balanced to provide enough energy and protein for animals, and they should include enough forage to keep the rumen healthy. Animals also need access to fresh water at all times.
