The aim of this work was to study the lipid metabolism and energy status skeletal muscle pigs as affected by dietary protein restriction. Eighteen growing were distributed into three treatments, each group fed one levels (20, 17, 14%) crude (CP) diets. Our results showed that 20% CP had greater (P < 0.05) gain:feed weight than those 14% CP, but no differences between 20 17% treatments. Additionally, restriction tended increase = 0.07) content intramuscular fat (IMF) up-regulated expression lipogenic-related genes. Energy changed and, concomitantly, AMP-activated kinase α pathway inhibited reducing level. These indicate could be useful improve IMF through regulating associated utilization in muscle.
