摘要
本试验的分析表明,与罗姆尼相比,考力代不仅种羊易解决.而且适应性强,在我省条件下,对改进后代羊毛性能表现较好。因此,按照我省细毛羊育种指标的要求,引入号力代血液,对改进毛短、毛细、剪毛量和净毛率低等缺点有一定意义。但其后代仍可出现14％的半细毛个体,这一缺点,可通过加强选种选配,回交,一代横交来克服。
In comparison to Romney, Corridale is not only obtainable, but also has strong adaptability. Therefore, it is practical to use Corridale to improve the wool quality in Shanxi province. Although 14% of the progenies are still semi-fine wool sheep, such shortcoming will be hopefully overcome through selective breeding, back-breeding and offspring crossing.
