Methods for lowering the incidence of hemorrhagic heart disease in swine

A method of reducing the incidence of Mulberry heart disease in a Sus scrofa population comprising:

• identifying selection candidates in the population;
• for each selection candidate, determining i) an allele of a single nucleotide polymorphism corresponding to position 204959669 of chromosome 13 of Sus scrofa, or ii) an allele of a genetic marker in linkage disequilibrium with the single nucleotide polymorphism wherein the allele of the genetic marker in linkage disequilibrium with the single nucleotide polymorphism is perfectly predictive of an allele of the single nucleotide polymorphism;
• selecting parents from among the selection candidates based on the determined allele of the single nucleotide polymorphism or based on the determined allele of the genetic marker in linkage disequilibrium with the single nucleotide polymorphism in the population;
• and
• producing progeny from the parents.
