Fig. 6From: Betaine affects muscle lipid metabolism via regulating the fatty acid uptake and oxidation in finishing pigThe relative mRNA expression of factors involved in fatty acid oxidation in muscle. mRNA expression was performed by RT-PCR and β-actin was chosen as reference gene. a,bValues without common superscript letters differ significantly (P < 0.05). Low betaine and high betaine represent 1250 mg/kg and 2500 mg/kg betaine addition, respectivelyBack to article page
