Heritability of the elk hunting traits in the Finnish Jämthund population

ABSTRACT The aim of our study was to estimate the genetic parameters of elk hunting traits in the Finnish Jämthund population. The phenotype data included 40 402 trial observations recorded in Finland between 2012 and 2020 and the pedigree data included information of 34 495 Jämthunds. The genetic parameters of the elk hunting traits were estimated using a repeatability animal model. Season, place, and type of the trial, weather during the trial, and dog sex and age were considered fixed effects in the models, and trial judge and dog litter were treated as random effects. Variance components were estimated with the AI-REML method using the DMU-software. Heritability estimates were generally low (0.01–0.04). The highest estimated heritability was 0.04 for searching. Repeatability estimates for elk hunting traits varied between 0.04 and 0.14. Genetic correlations varied from very weak to very strong (−0.21–1.00) and were particularly strong between the barking traits.

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.
