In today’s swine industry, few producers or nutritionists would consider feeding pigs without giving great attention to energy and amino acid concentrations and ratios, and to optimum vitamin and mineral supplementation. Selection of reasonably priced, good-quality ingredients and proper processing of those ingredients into complete diets is equally important to the overall profitability of a swine farm, yet good feed manufacturing practices often are given little emphasis. This chapter is a review of basic considerations for feed manufacturing that can be used to maximize nutritional value of ingredients and complete diets for pigs.
