ABSTRACT: Growth rate affects adipose tissue development and variations in growth rate may potentially impact adipokine expression. Samples of subcutaneous (SQ) and perirenal (PR) adipose tissues and longissimus muscle were collected at day 21 of age from the fastest and slowest growing piglets within seven litters. Reverse transcription and real-time PCR were used to quantify adipokine mRNA abundance. Leptin, adiponectin, tumor necrosis factor α (TNFα ) and lipoprotein lipase (LPL) mRNA abundance were lower in SQ from slow growing piglets (SGP) than in fast growing piglets (FGP, P α gene expression were reduced in PR from SGP in comparison to FGP (P β (IL1β), IL15 and LPL were increased in the longissimus of SGP relative to FGP (P
