Abstract

ABSTRACT Norwegian Elkhound Grey is used for both leashed and non-leashed tracking. This study provides influence of fixed effects and estimates of genetic parameters of traits related to both types of tracks. In total, 5393 records from 1991 animals tested in the years 1995–2014 on lashed performance (5 traits), and 5405 records from 2070 animals tested in the years 2005–2014 on non-leashed performance (10 traits) were included in the dataset. The pedigree file contained 8623 animals. Heritabilities were generally low for the non-leashed traits and a bit higher for the leashed traits. Genetic correlations within trait group were very highly positive for the leashed dog traits, but variable among some traits in the non-leashed group. Genetic correlations between performance traits in the two groups were generally negative and unfavourable. Genetic trends were generally positive for the time periods.

挪威麋鹿系带和非系带试验系统狩猎性状的遗传分析

挪威灰elhhound Grey用于牵引和非牵引跟踪。本研究提供了固定效应的影响，并估计了与这两种类型的轨道相关的性状的遗传参数。该数据集共包括1995-2014年对1991只动物进行捆绑性能(5个性状)测试的5393条记录，以及2005-2014年对2070只动物进行非捆绑性能(10个性状)测试的5405条记录。谱系文件包含8623只动物。非系带性状的遗传力一般较低，系带性状的遗传力略高。在性状组内，系带犬的性状遗传相关呈极显著正相关，而在非系带犬组中，部分性状遗传相关存在差异。在两组中，表现性状之间的遗传相关性通常是负的和不利的。在这段时间里，遗传趋势总体上是积极的。
