Formulation of a ration or diet requires knowledge of the nutrient requirements of the animal (discussed in this part) and the nutritional value of the foods (discussed in Part 3) and, in order to combine these two, the amount of foods the animal can consume. Therefore, Chapter 17 gives details of factors affecting food intake in both monogastrics and ruminants and the methods used to predict food intake. 

The main users of feeding standards are commercial companies that supply concentrate feeds as complete diets for pigs and poultry and as complementary feeds to forages consumed by ruminants. Nutritional advisers and consultants also use them to formulate diets and advise farmers. Commercial feed companies often modify published standards in order to meet the specific needs of their customers. For example, the nutrient requirements of poultry tend to change from one generation to the next because of the speed of genetic selection and improvement. Consequently, national feeding standards fail to...
