Fermented mixed feed alters growth performance, carcass traits, meat quality and muscle fatty acid and amino acid profiles in finishing pigs.

ABSTRACT: This study was conducted to investigate the effects of fermented mixed feed (FMF) on growth performance, carcass traits, meat quality, muscle amino acid and fatty acid composition and mRNA expression levels of genes related to lipid metabolism in finishing pigs. In the present study, 144 finishing pigs (Duroc × Berkshire × Jiaxing Black) were randomly allocated to 3 dietary treatments with 4 replicate pens per group and 12 pigs per pen. The dietary treatments included a basal diet (CON), a basal diet + 5% FMF and a basal diet + 10% FMF. The experiment lasted 38 d after 4 d of acclimation. The results showed that 5% and 10% FMF significantly increased the average daily gain (ADG) of the females but not the males (P < 0.05), but FMF supplementation showed no impact on carcass traits.
