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.
期刊介绍：
Acta Agriculturæ Scandinavica, Section A – Animal Science publishes results of original research in animal science and their applications related to the following topics:
-Animal breeding and genetics
-Molecular genetics
-Animal physiology and reproduction
-Nutrition and feeding
-Animal behaviour and welfare
-General animal husbandry and systems of production, including economic and technical aspects
-Hygiene and quality of animal products
In addition to original articles, covering basic as well as applied subjects, the journal features review articles and short communications.
Acta Agriculturæ Scandinavica, Section A – Animal Science forms part of a trilogy of titles published on behalf of the Nordic Association of Agricultural Scientists (NJF). The series also includes Section B - Soil & Plant Science and the recently launched Section C - Food Economics .
Acta Agriculturae Scandinavica A, B and C are available to purchase as a combined subscription. This provides access to all three journals in the series, and is available to institutional subscribers only. For full pricing information, please view the Taylor & Francis Journals Price List here.
Scientists in research, teaching and extension with specialised interest in animal science and production.
