Abstract:

This study aims to investigate the effects and mechanisms of salidroside on bone metabolism in a methylprednisolone-induced animal model of femoral head necrosis in broilers. Thirty-two 1-day-old Arbor Acres broiler chickens were randomly divided into a control group, a methylprednisolone group, a salidroside intervention group, and a salidroside control group, with 8 chickens in each group. At 42 days of age, the chickens were subjected to gait scoring and weighing, followed by the collection of blood and liver samples for triglyceride and total cholesterol analysis. Femoral head tissue samples were collected for bone metabolism marker analysis, and femur and tibia samples were taken for bone density and strength testing. Results were as follows: Compared to the methylprednisolone group, the salidroside intervention group showed a significant increase in body weight, femur weight, length, Young's modulus, and fracture load, as well as a significant increase in tibial stiffness; The transcription of Collagen-1 and Runx2 genes in the femoral head was significantly upregulated; There was a reduction in cartilage lacuna vacuolation, with significant upregulation of Collagen-2, Aggrecan, and BMP2 gene transcription in cartilage; a significant downregulation of MMP13 gene transcription; the levels of triglycerides and total cholesterol in the liver and serum significantly decreased; the expression of FASN and SCD1 genes in the femoral head was downregulated. The results indicate that salidroside can regulate lipid metabolism and cartilage matrix synthesis, and alleviate methylprednisolone induced femoral head necrosis in broiler chickens.
