Key Points

This study aims to investigate the effects of high-fiber, low-energy feed on carcass and meat quality traits in Jinhua and Duroc composite-breed pigs.
Compared two feed types: low-energy feed (73% TDN) and conventional feed (77% TDN).
Used 24 pigs (12 with low-energy feed and 12 with conventional feed) for the experiment.
Measured backfat thickness at specific vertebrae and compared carcass weights.
Low-energy feed group showed reduced backfat thickness at vertebrae 9 to 13 (p<0.05).
Thickness of mid-layer backfat significantly decreased in the low-energy feed group (p<0.05).
No significant differences were found in overall meat quality traits between the two groups.

Evaluates carcass and meat quality traits in composite-breed pigs, suggesting dietary adjustments may reduce excessive fat accumulation.
