Krškopolje pig is the only Slovenian authochtonous pig breed, that is lately gaining the importance due to demands of global goals of sustainable development (biodiversity, animal welfare, sustainable use of natural resources, food quality). Similar to other local pig breeds, it remains poorly exploited and studied. Data on performance, nutritional requirements, carcass properties and meat quality traits are lacking, as well ad in-depth studies on genetic and metabolic level. Studies in controlled environmental conditions and with comparison to modern breeds are required. Profound characterization of Krškopolje pig genetic structure and metabolic properties in association to other phenotypic traits is needed to better understand their relation to performance and meat quality ensuring sustainable breed development, including its conservation. In porder to respond to the foreseen objectives of the project, experimental work will be organized in two main tasks, corresponding to either genetic or metabolic characterization of Krškopolje pig, respectively. As for the genetic characterization, the proposed research aims to advance the present knowledge on the genetic variability of Krškopolje pig population and to perform a genotype-phenotype association studies. Whole genome sequencing of individuals and genotyping with SNP array will be carried out on a representative sample ob the breed population. The second task will investigate Krškopolje pig breed at the level of geneexpression (using either candidate gene or transcriptomic approach) together with histological, biochemical and qualitative characterization. Comparison of conventional lean breed to Krškopolje pigs, and rearing under different dietary conditions, will be tested. Special emphasis will be given to adipose tissue deposition (differentiation, hypertrophy), lipid metabolism (fatty acid synthesis and desaturation) and muscle metabolic profile (myofiber metabolic type), also in relation to fat and meat quality. The obtained information will enable a deeper insight int the genotype-phenotype association, further elucidating metabolic properties of traditional fatty type breeds and with results help to enhance the exploitation of Krškopolje pig potential. In addition, the study will also aid to understand fat and muscle tissue metabolism in general.
