摘要
在昆明犬育种核心群的选育中,通过组建核心群,实行等级选配、品质选配与亲缘选配等综合技术措施制定选育方案。经连续三个世代的选育研究,结果表明:三级种公犬所占比例分别为41%(种犬等级)和37%(训练等级),比母犬相应高;在各项体尺测量中,现有种犬核心群除母犬的体高、荐高、胸深以及公犬的胸深低于1987年的统计结果外,其余都高于1987及2001年的统计结果,但差异不显著(P>0.05);繁殖性能方面,现有育种核心群窝产仔数(9.18±3.5)、产活仔数(8.55±2.8)都显著高于1987年的统计结果(P<0.01)。
The study mainly researched the selective breeding of core flock of Kunming Dog, through a series of techniques of constructing core flock, mating selected in rank. quality, affinity and so on. After the three-generation selection, the result showed that the thirdclass male dogs occupy a proportion of 41% （breeding dog） and 37%（working dog）,Which is higher than female dogs. The body size, besides the body height, back height of female dogs, breast depth of male dogs and female dogs in the core flock, were higher than that of 1987 and 2001 ,but no significant difference （P〉0. 05）;the pup count of nest（9.18±3.5）and the number of born alive（8.55±2.8）in existed core flock are significant higher than that of 1987 （P〈0. 01 ）.
