摘要/Abstract

摘要： 为探讨影响种猪活体性状测定的因素，以杜洛克猪、长白猪、大约克夏猪为对象，采用B超测定仪对每头试验猪个体的背膘厚、眼肌深度和眼肌面积进行测定，对所测结果进行相关性分析和方差分析，并建立回归模型。结果表明，B超测定种猪活体性状的结果受品种和结测体重影响，与测定人员的实操技能有关，且受检测设备的制约；背膘厚平行法与垂直法测定结果呈显著性正相关，相关系数达0.836，且差异不显著，可以相互替代。上述结果为规范种猪生产性能测定技术规程提供科学依据。

关键词: 种猪, B超, 背膘厚, 眼肌深, 眼肌面积

Abstract: In order to investigate the factors influencing pig live performance, this paper took Duroc, Landrace and Large Yorkshire as the objects and tested the back fat thickness, eye muscle depth and eye muscle area of each experimental pig by B-mode equipment. The data were analyzed by correlation analysis and variance analysis, and regression equation was built. The results showed that measurement of pig live performance by B-mode equipment was affected by breed type, final weight; related to operation skill of the tester, and also limited by the test equipment. There were no significant differences between back-fat thickness testing results by parallel viewing and cross viewing. So these 2 methods could replace each other. Above results provided scientific basis for standardizing the technical regulations for production performance measurement of breeding pigs.

Key words: pig, B-mode equipment, back-fat thickness, eye muscle depth, eye muscle area
