波德代、陶赛特与蒙古羊的高代杂种血液生化指标比较

Comparative research of blood bio-chemical indexes of Mongolia sheep and its latter generations of Borderdale×Mongolia and Poll Dorset×Mongolia hybrid

对波德代、陶赛特与蒙古羊的高代杂种5个品种12项血液生化指标进行了测定.结果表明:5个品种血清钙含量依次为蒙古羊(M)(2.58±0.98)mmol/L,陶赛特×蒙古羊杂种二代(DMF2)(1.95±0.24)mmol/L,波德代×蒙古羊杂种二代(BMF2)(1.99±0.17)mmol/L,陶赛特×蒙古羊杂种三代(DMF3)(1.84±0.21)mmol/L,波德代×蒙古羊杂种三代(BMF3)(1.89±0.32)mmol/L,均低于正常值(3.91±0.17)mmol/L;血清磷含量依次为M(1.83±0.70)mmol/L,DMF2(3.28±0.96)mmol/L,BMF2(2.73±1.01)mmol/L,DMF3(2.64±0.85)mmol/L,BMF3(3.01±0.56)mmol/L,均高于正常值(1.16±0.28)mmol/L,其它生化指标都在正常值范围内或与正常值相近.而与生产性能有关的血清总蛋白、白蛋白、钠含量高代杂交羊均高于当地蒙古羊,表明高代杂交羊对当地自然生态环境和饲养管理条件有较好的适应性,能较好地发挥其肉用遗传潜力.

Twelve blood bio-chemical indexes of five breeds of Mongolia sheep and its latter generations of Borderdale × Mongolia,Poll Dorset × Mongolia were studied. The results showed that the serum Ca^2＋ content of five breeds was lower than the standard（3.91±0.17 mmol/L）,while the serum P content was higher than the standard（1.16±0.28 mmol/L）,and other ten indexes were normal or approached to the standard. The total protein, albumin and Na^＋ of serum of four latter generations,which were relative to production performance, were higher than those of local Mongolia sheep. In short, hybrid sheep were adapted to the local natural ecological environment and raising management condition very well and could bring their genetic potential in mutton production into full play.
