Abstract:

Objective This study aimed to investigate the effects of dietary supplementation with Lycium ruthenicum Murr. extract of different concentrations on lipid profiles, adipose tissue morphology, and the expression of lipid metabolism-related genes and proteins in Bamei ternary hybrid pigs. Method Forty-eight Bamei ternary hybrid pigs aged (50±2) days with an average weight of 7.83 kg±0.52 kg were randomly divided into four groups, with three replicates per group and four pigs per replicate. The pigs were fed either a basal diet (CON group) or diets supplemented with 5, 10, and 15 g/kg of Lycium ruthenicum Murr. extract (LE, ME, and HE groups), respectively. The experimental period was 42 days. At the end of the experiment, two pigs from each replicate were slaughtered, and blood, abdominal subcutaneous fat, and epididymal fat tissue were collected for the measurement of serum lipid levels, observation of fat tissue cell morphology, and mRNA and protein expression of lipid metabolism-related factors in fat tissues. Result Compared with CON group, ①Serum triglyceride (TG) levels of pigs in LE, ME, and HE groups were significantly reduced (P<0.05), serum total cholesterol (TCH) levels were significantly reduced (P<0.05), and serum high-density lipoprotein cholesterol (HDL-C) levels in LE group were significantly increased (P<0.05). ②The area of lipid droplets in the subcutaneous adipose tissue of the abdomen of pigs in ME group was significantly reduced (P<0.05), while there was no significant difference in the area of lipid droplets in the epididymal adipose tissue (P>0.05). ③ In LE, ME, and HE groups, the mRNA and protein expression of lipid synthesis-related factors (PPARγ, ACC, and SREBP1) in abdominal subcutaneous fat and epididymal fat were significantly or extremly significantly reduced (P<0.05 or P<0.01), while the mRNA and protein expression of lipid degradation-related factors (CPT1 and HSL) were significantly or extremly significantly up-regulated (P<0.05 or P<0.01). Conclusion Adding Lycium ruthenicum Murr. extract to the diet could significantly reduce lipid deposition in the abdominal subcutaneous fat of Bamei ternary hybrid pigs by inhibiting the expression of lipid synthesis-related factors (PPARγ,ACC,and SREBP1) and promoting the expression of lipid degradation-related factors (CPT1 and HSL), with the 10 g/kg addition showing the best effect.
