Abstract
- A feeding trial for 91 days was conducted to investigate effects of active immunization against porcine Sox6 (pSox6) on meat quality and myosin heavy chain (MyHC) isoform expression in growing-finishing pigs. Twenty-four castrated Duroc × Landrace × Yarkshire pigs were randomly divided into three groups: (1) Control group; (2) 1 mg/head pSox6 active immunity group; (3) 4 mg/head pSox6 active immunity group (4 mg/head group). The results showed that pigs in 4 mg/head group had a greater a* (Redness) and a higher marbling score, while no significant effect was observed in L* (Lightness), b* (Yellowness), intramuscular fat and cooking loss. Muscle succinic dehydrogenase activity in pSox6 active immunization groups was significantly increased, and muscle lactate dehydrogenase activity was significantly reduced. Meanwhile, active immunization against pSox6 upregulated the mRNA expression of MyHC I , while no effect was observed on the mRNA expressions of MyHC IIa , MyHC IIx , MyHC IIb . In addition, pigs in the 4 mg/head group exhibited lower Sox6 mRNA level and higher MyHC I protein level, while no significant influence was observed on MyHC IIb protein level. Together, our data imply that active immunization against pSox6 could improve the pork quality and promote the MyHC I expression in growing-finishing pigs.
