Development, recording, validation and optimization of functional traits of Austrian sows and piglets
Abstract
Due to various changes in the Austrian pig breeding industry, comprising housing restrictions, ethical demands of consumers, political concerns and global market changes, the Austrian pig breeders have to revise their breeding goals concerning functional traits. The aims of the project are to define maternal abilities by breeders and to implement the defined parameters into routine recording. The project comprises 5 work packages. The first one includes the recording of direct maternal traits antepartum and postpartum, respectively. Traits are recorded on around 2.200 sows (Large White and Landrace) directly by the breeders. Breeders are will be trained for the assessment of the maternal traits. Regarding the data quality, genetic parameters will be estimated. The second work package includes the assessment leg conformation traits. This will be done by staff of the breeding organisations. Furthermore in the third work package, the vitality of piglets will be considered. Therefore, a vitality index will be set up, including different information of piglets and litters, respectively (weight, heterogeneity of litters, etc.). The information of around 30.240 piglets will be included in the analyses. This index will be implemented into routine genetic evaluation to improve piglet survival and piglet welfare. Genetic parameters will be estimated. In order to understand the economic impact of the new trait(s), calculations concerning the breeding programs using Z-Plan will be done in the fourth work package. In this project functional traits are of interest. However, the conventional way to estimate breeding values is not sufficient enough to increase genetic gain, since the new traits are all lowly heritable. Therefore in work package five, sows will be genotyped to optimise genetic evaluation and to improve reliabilities of estimated breeding values. All the results (definition and recording of maternal abilities, genetic parameters, genomic information, etc.) will be included into routine genetic evaluations to genetically optimise the Austrian pig population, to increase animal welfare and to meet farmer’s economic demands.
