Effect of single nucleotide polymorphism on the total number of piglets born per parity of three different pig breeds.

Objective: To determine the effects of genomic breeding values (GBV) and single nucleotide polymorphisms (SNP) on the total number of piglets born (TNB) in 3 pig breeds (Berkshire, Landrace, and Yorkshire).

Methods: After collecting genomic information (Porcine SNP BeadChip) and phenotypic TNB records for each breed, the effects of GBV and SNP were estimated by using single step best linear unbiased prediction (ssBLUP) method.

Results: The heritability estimates for TNB in Berkshire, Landrace, and Yorkshire breeds were 0.
