“…In modern pig industry, the artificial breeding of pig traits such as lean meat rate and growth rate has inevitably resulted in the decline of meat quality, which has gradually become the main problem facing the pig industry in China. Specifically, meat quality is mainly measured by meat colour (Büyükalaca & Bulut, ), pH value(Wood et al, ), water binding capacity (WBC) (Luciano et al, ; Otto et al, ), intramuscular fat (IMF) (Davoli & Braglia, ) and meat tenderness (Caine, Aalhus, Best, Mer, & Jeremiah, ). Additionally, muscle fibre type is one of the important factors that determine meat quality.…”
