Simple Summary We estimated genetic parameters and conducted genomic prediction for
five types of sperm morphology abnormalities in a large Duroc boar population. Results
reflect that the studied traits showed moderate to low heritability and moderate to high
repeatability. Both genomic best linear unbiased prediction (GBLUP) and single-step
GBLUP (ssGBLUP) showed comparative predictive abilities, and ssGBLUP outperformed
GBLUP under many circumstances. To our knowledge, this is the first time that the genetic …

Artificial insemination (AI) has been used globally as a routine technology in the swine
production industry. However, genetic parameters and genomic prediction accuracy of
semen traits have seldom been reported. In this study, we estimated genetic parameters and
conducted genomic prediction for five types of sperm morphology abnormalities in a large
Duroc boar population. The estimated heritability of the studied traits ranged from 0.029 to
0.295. In the random cross-validation scenario, the predictive ability ranged from 0.212 to …
