Effect of a Reduced-Protein Diet Supplemented with Essential Amino Acids on the Muscle Proteome of Female and Entire Male Finishing Pigs.

ABSTRACT: Crude protein (CP) decrease coupled to amino acid (AAs) supplementation is interesting for swine nutrition. A proteomics approach unraveled physiological events underlying differences between sexes fed two diets: control and low CP in fast-growing Duroc X (Landrace X Large white) finishing pigs. Sixty animals per sex were distributed in pens (five replicate pens/group), fed ad libitum with two isoenergetic diets (145 vs. 125 g CP/kg with AA supplementation; control and low-CP) for 42 days. Semimembranosus muscle was sampled. Five samples per group were used for Label Free proteomics. Four comparisons were considered: Control Males vs. Control Females; Control Females vs. Low CP females; Control males vs. Low CP males, and Low CP males vs. Low CP females, identifying, respectively, 2
