| 摘 要： | 对猪的Ag—NOR_s与其肥育性能相关分析结果表明,二者间呈显著负相关。猪品种的Ag—NOR_s均数、8Ag—NOR_s~+平均染色体型频率与日增重和瘦肉率间的相关系数分别为-0.5968(P<0.01)和一0.6235(P<0.005);-0.6550(P<0.005)和-0.7036(P<0.001);个体的Ag—NOR_s均数、8Ag—NOR_s~+染色体型频率与日增重的相关亦高达-0.6591(P<0.05)和-0.4984(0.1>P>0.05)。Ag—NOR_s有可能作为一项选种指标,用于猪肥育性能的选择。

| Abstract: | The correlation between Ag-NORS and fattening performance in swine was analysed in this study. The result showed that there was a significant negative correlation between them. In pig breeds, the correlation coefficients between the mean of Ag-NORs, 8Ag-NORs+ average chromosome-type frequencies and daily gain, lean meat percentage were -0.5968(P<0.01) and -0.6235(P<0.005); -0.6550(P< 0.005) and -0.7036(P< 0.001) respectively. In individuals, the correlation coefficients between the mean of Ag-NORs, 8Ag-NORs+ chromosome-type frequencies and daily gain were -0.6591(P<0.05) and -0.4984(0.1 >P>0.05). There was a tendency that Ag-NORs could be used as a selection criterion for fattening performance in swine. |
