Reprinted with permission. Energy values are estimated based on a consumption rate 3 times the rate of consumption at maintenance. These are representative values intended primarily for relative comparison among feeds. Analyzed values of actual feed samples will vary substantially, especially among forages. Laboratory analyses of feeds and forages are always advisable for both comparative evaluation and ration balancing. | ||||||||
