Impact of dietary protein on lipid metabolism-related gene expression in porcine adipose tissue.

ABSTRACT:

Background

High dietary protein can reduce fat deposition in animal subcutaneous adipose tissue, but little is known about the mechanism.

Methods

Sixty Wujin pigs of about 15 kg weight were fed either high protein (HP: 18%) or low protein (LP: 14%) diets, and slaughtered at body weights of 30, 60 or 100 kg. Bloods were collected to measure serum parameters. Subcutaneous adipose tissues were sampled for determination of adipocyte size, protein content, lipid metabolism-related gene expression, and enzyme activities.

Results

HP significantly reduced adipocyte size, fat meat percentage and backfat thickness, but significantly increased daily gain, lean meat percentage and loin eye area at 60 and 100 kg. Serum free fatty acid and triglyceride concentrations in the HP grou
