Summary and Implications

The purpose of this study was to estimate the relationship between purebred and crossbred sow reproductive performance. The relationship between purebred and crossbred performance is the foundation of all successful breeding programs. The heritability estimates for all traits ranged from 0.11 to 0.22. The estimated genetic correlations (standard error) for NBA and NBD between the first parity at the nucleus level and parities 2 and greater at the commercial level were 0.98 (±0.20) and 0.40 (±0.22), respectively. The results of this study indicate that a relationship between purebred and crossbred performance exists. Thus, selection on purebred individuals may result in improvement in crossbred performance.
