Boar-to-Boar Variations in Quality Characteristics of Sperm from Different Ejaculates Following Freezing-Thawing.

ABSTRACT: The main objective of this study was to investigate boar-to-boar variations in the quality characteristics of sperm from the sperm-rich fractions (SRFs) and whole ejaculates (WEs) following freezing-thawing. Several sperm attributes, such as motility patterns analyzed by the computer-assisted sperm analysis (CASA) system, mitochondrial function, membrane integrity, and DNA fragmentation were used to compare the cryo-survival of sperm from SRFs and WEs from boars with good and poor semen freezability (GSF and PSF, respectively). In this study, boars with post-thaw total motility (TMOT) more than 30% (>30%) were classified as having GSF, while those with post-thaw TMOT less than 30% (<30%) were classified as having PSF. Principal component analysis 1 (PCA1), which is the main component of th
