The invention discloses a method for manufacturing a fermentation bed for livestock cultivation and a method for breeding pigs on the fermentation bed. The livestock cultivation fermentation bed is characterized by being manufactured by paving a loess layer on a foundation layer of an organic gasket and sprinkling sodium chloride, brown sugar and strains consisting of compound microbial inoculants where effective microorganisms and indigenous microorganisms coexist, rice bran and wheat bran on the loess layer. Green feed serves as main feed for the pigs on the fermentation bed, and energy feed and supplementary feed consisting of Chinese medicaments having the functions of benefiting gastrointestinal health, facilitating digestion and expelling toxin to improve the immunity of the pigs also can be fed to the pigs. Compared with the prior art, the livestock cultivation fermentation bed has the advantages that the pigs bred on the bed have strong immunity, need no vaccines and antibiotic and can be fed with the green feed for bulls and sheep; and the meat of the bred pigs has the same pleasant taste as wild pigs.

The invention provides a major SNP (single nucleotide polymorphism) marker influencing the growth traits of pigs. The SNP marker is located at a nucleotide sequence of an HMGA1 gene of a pig chromosome 7, a locus of the SNP marker is the nucleotide mutation of C857-G857 with an SEQ ID NO:1 sequence labeling position of 857, corresponding to a 34983991st nucleotide locus C> on chromosome 7 in a reference sequence in an international pig genome version 10.2, G mutation, or one of seven other loci completely linked with the locus. The invention also provides the application of the SNP marker in the genetic improvement of growth traits of breeding pigs, and provides the application of an SNP molecular marker with a linkage disequilibrium degree (r2) with the SNP marker of greater than 0.8 in the genetic improvement of growth traits of breeding pigs.
