摘要: 本研究旨在探讨双能X射线在绵羊肌内脂肪(IMF)含量等营养指标测定中的应用价值。试验选取19只8月龄蒙古绵羊作为研究对象,利用索氏抽提法测定IMF含量,利用组织成分检测仪测定胴体骨密度(BMD)、胴体单位矿物质的脂肪含量(FBMC)、胴体单位矿物质的肌肉含量(LBMC)、后腿单位矿物质的脂肪含量(LFBMC)、后腿单位矿物质的肌肉含量(LLBMC) 5个指标,再将这些指标进行相关性分析、通径分析及回归方程的构建。结果显示,FBMC对IMF的决定程度最大,且FBMC与IMF构成的回归方程极显著,表明可通过检测FBMC来进行绵羊胴体IMF的预测。该研究为双能X射线在肉品质快速评定中的应用提供了必要的依据。

Abstract: In order to study the value of application in determining the intramuscular fat (IMF) content and other nutrition with dual energy X-ray.Nineteen Mongolian sheep at 8 months of age were chosen to determine the IMF content by soxhlet extractor method and tissue components tester was used to determine the carcass bone density (BMD), fat content of carcass unit minerals (FBMC), the muscle content of carcass unit minerals (LBMC), fat content of the hind legs unit minerals(LFBMC) and hind legs muscle content unit minerals(LLBMC), and these indicators were analyzed by correlation analysis, path analysis and establishing regression equation.The results showed that FBMC had the most significant determinative effects on IMF, and the regression equation consisted of FBMC and IMF was greatly significant differences.Consequently, according to FBMC could predict the IMF in Mongolian sheep carcass.This study provided the necessary basis for the application of dual energy X-ray in the rapid evolution of meat quality.

Key words: intramuscular fat; dual energy X-ray; carcass; sheep
