Abstract

Through genetic selection pigs now deposit relatively more protein and less fat than they did twenty years ago, primarily because of the pressure from consumers to reduce the amount of subcutaneous fat on pork products. As a consequence, the requirement for amino acids relative to energy has slowly increased over this time. It has been several years since experiments to determine the requirement for amino acids relative to energy have been conducted on Australian pig genotypes. The hypothesis of this experiment was that grower pigs will respond to increasing levels of available lysine (Av Lys) per MJ digestible energy (DE) by having an increased growth rate and improved feed conversion ratio, until a plateau is reached at their genetic potential.
