Special Issue Information

Dear Colleagues,

The continuous advancement of genetic technologies and methodologies presents unprecedented opportunities for the pig industry, enhancing productivity, health, and environmental sustainability. The "Genetic Improvement in Pigs" Special Issue seeks to encapsulate the cutting-edge research and innovative strategies occurring in the pig genetics, breeding, and biotechnology fields. This issue will explore the latest developments in genetic improvement efforts, including, but not limited to, genomic selection, gene editing, genetic diversity, and disease resistance. We aim to provide a comprehensive platform for researchers, breeders, and industry practitioners to disseminate their findings, share insights, and discuss future directions regarding the genetic enhancement of pigs. This Special Issue will delve into the genetic underpinnings of important traits, the application of next-generation sequencing technologies, and the ethical, economic, and social implications of genetic improvements in swine production. Our objective is to highlight research that contributes to the sustainable and ethical advancement of the pig industry, offering insights into practical applications and theoretical frameworks that drive genetic progress.

Artificial insemination plays a crucial role in pig production, particularly in enhancing the genetic potential of elite boars. To accelerate genetic progress for semen traits in pigs, it is vital to understand and identify the underlying genetic markers associated with desirable traits. Herein, we genotyped 1238 Landrace boars with GeneSeek Porcine SNP50 K Bead chip and conducted genome-wide association studies to identify genetic regions and candidate genes associated with 12 semen traits. Our study identified 38 SNPs associated with the analyzed 12 semen traits. Furthermore, we identified several promising candidate genes, including HIBADH, DLG1, MED1, APAF1, MGST3, MTG2, and ZP4. These candidate genes have the potential function to facilitate the breeding of boars with improved semen traits. By further investigating and understanding the roles of these genes, we can develop more effective breeding strategies that contribute to the overall enhancement of pig production. The results of our study provide valuable insights for the pig-breeding industry and support ongoing research efforts to optimize genetic selection for superior semen traits. Full article
