This edition retains all of the data in the 10th that has not been revised by new research findings. The tables of feed ingredient composition were among the material that needed updating, so the committee reviewed the published data and completely revised both the format and the content of the 130-page tables. Other topics include proteins and amino acids, water, models for estimating nutrient requirements of swine, food contaminants, the digestibility of nutrients and energy, and nutrient requirements tables.
