The use of net energy as a more precise system to formulate swine diet

Feeding swine is the most important cost of pork production accounting for up to 70% of the variable costs. Within feed price, energy appears as principal factor affecting price. Optimal energy system is very important in order to control cost and best meet animal needs. Net energy system is currently the most suitable system for animal deposition and has already been adopted by about 50% of the worldwide swine feed production operation.
