摘      要：With the increasing demand for high-quality pork,more nutritional substances have been studied for the regulation of meat ***-dimensional fullerenes(C60)can modulate the biological behavior of a variety of cell lines and *** this study,we report the biological effects of C60 on finishing pigs at different concentrations.A total of 24 barrows(Duroc×Large White×Landrace),with an average body weight of 21.01±0.98 kg,were divided into 3 groups and each treated daily with C60(100 or 200 mg per kg feed)or a control diet until the end of the *** results showed that dietary C60 supplementation improved flesh color,marbling scores,and flavor amino acid contents of longissimus dorsi(LD)of growing-finishing pigs(P0.05).C60 improved meat quality by regulating lipid metabolism and muscle fiber morphology by mediating the expression of genes,L-lactic dehydrogenase(LDH),myosin heavy chain(MyHC)IIa,MyHCIIb,peroxisome proliferator-activated receptor γ(PPARγ),and fatty acid transport protein 1(FATP1)(P0.05).Moreover,C60 substantially promoted the mRNA expression of antioxidant enzyme genes(P0.05),which also contributed to improving meat *** findings have important implications for the application of C60 in the livestock industry,especially for improving the meat quality of fattening pigs.
