| 摘 要： | 本研究采用公畜内半同胞相关法，分别从产奶量（350头）、耐热产奶量（116头）、直肠温度（200头）和红细胞钾（144头）四个方面估算奶牛群体遗传力，结果分别是0．334、0．196、0．20、0．318．利用SAS8．1版本对数据进行二元回归分析，得到回归方程：y=0．23853-0．0096xa＋0．000827x2（x1为直肠温度，x2为红细胞钾含量）．运用BLUP法估算公牛育种值，以色列公牛育种值最高，为85．12． |

| Abstract: | The heritability ill milk yield（350 caput）, heat tolerance milk yield （350 caput）,recta temperature（350 caput） and potassium concentrate of erythrocytes（350 caput）were estimated using half-fellowmen correlation in bull. The results were 0.334, 0.196, 0.20 and 0.318 respectively. Using SASS.1 to analysis the data,got the dualitye linear regression equation mezu： y=-0.23853-0.0096xl＋0.000827x2 （xl as rectal temperature,x2 as potassium concentrate of erythrocytes）.The breeding value of Israel bulls estimated by BLUP method was 85.12 and it is the highest among the bulls. |
