摘要
以2017年上半年在农业部种猪质量监督检验测试中心(广州)集中测定的种猪性能测定成绩为研究数据,使用统计工具SPSS,探究集中测定环境下被测种公猪的剩余采食量(RFI)与背膘厚、眼肌面积、日增重等校正生产指标的相关性,分析了根据RFI分组的不同组间的指标异同,发现RFI与饲料效率有极显著相关,与背膘厚、眼肌面积、日增重等无显著相关。提出结合RFI指标评价种公猪饲料效率,可为选择终端父本提供更多参考。
The data of breeding swine performance tested in Breeding Swine Quality Supervision Inspection & Testing Center of Ministry of Agriculture was analyzed with SPSS to study the relationship between corrected performance as backfat thickness, loin eye area, weight gain and residual feed intake(RFI). Significant corelation was find between RFI and feed efficiency, reveals it could be used as an efficient reference for the selection of the terminal sire.
