摘要
为了研究南方黄牛胴体质量分级问题,采用指标征集、因子分析、相关性分析等方法对南方黄牛胴体质量分级指标进行分析筛选,然后对筛选出来的大理石花纹、体型等级、眼肌面积等指标进行聚类分析,确定以大理石花纹(脂肪含量)作为胴体质量分级的指标。结果表明:根据大理石花纹得出分级标准为:第1类:1.32%≤大理石花纹<7.36%;第2类:7.36%≤大理石花纹<17.86%;第3类:17.86%≤大理石花纹<22.43%;第4类:大理石花纹≥22.43%。
In this paper, carcass quality indicators for carcass grading of yellow cattle from south China were screened and analyzed by factor analysis and correlation analysis. Cluster analysis was carried out on the selected parameters including beef marbling, body type and loin eye muscle area. These analyses confirmed beef marbling （fat content） to be the quality indicator for carcass grading. The grading standards based on beef marbling were established as follows： grade 1, 1.32%≤ marbling〈 7.36%; grade 2, 7.36%≤ marbling〈 17.86%; grade 3, 17.86%≤ marbling〈 22.43%; and grade 4, marbling≥ 22.43%.
