%X <span style=\"font-family:Verdana;\">Our aim was to evaluate the quality of
ejaculated and epididymal frozen-thawed </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">pig sperm of endangered Vietnam native pig breeds.
Ejaculated sperm was collected from live boars and epididymal sperm was
collected from slaughtered boars of the </span><i><span style=\"font-family:Verdana;\">MuongTe</span></i><span style=\"font-family:Verdana;\">,</span><i><span style=\"font-family:Verdana;\"> Kieng Sat </span></i><span style=\"font-family:Verdana;\">and </span><i><span style=\"font-family:Verdana;\">Co BinhThuan</span></i></span><i><span style=\"font-family:&quot;\"> </span></i><span style=\"font-family:Verdana;\">breeds and frozen in 0.25</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">ml straws using a protocol established earlier for
modern pig breeds. We evaluated the sperm quality after thawing in terms of
motility and rates of viable and abnormal spermatozoa. Our results revealed
that the sperm motility</span><span style=\"font-family:Verdana;\"> and</span><span style=\"font-family:Verdana;\"> rates of viable and
abnormal frozen-thawed sperm were &gt;30%, &gt;44%, </span><span style=\"font-family:Verdana;\">and</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\"> &lt;14%, respectively. The origin of sperm had an
effect on the production of pig embryos </span><i><span style=\"font-family:Verdana;\">in
vitro</span></i><span style=\"font-family:Verdana;\">.</span><i> </i><span style=\"font-family:Verdana;\">In the </span><i><span style=\"font-family:Verdana;\">Co BinhThuan</span></i><span style=\"font-family:Verdana;\"> breed, ejaculated sperm gener</span><span style=\"font-family:Verdana;\">ated higher
cleavage, blastocyst and hatching rates than did the epididymal</span><span style=\"font-family:Verdana;\"> sperm
(60.11% vs</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">56.02%, 17.23% vs 14.31%, 3.78% vs 2.34%,
respectively, P &lt; 0.05). Although no difference in cleavage rate, blastocyst
formation rate and the average number of cells/blastocysts</span><span style=\"font-family:Verdana;\">,</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\"> the hatching blastocyst rate was </span><span><span style=\"font-family:Verdana;\">different between the breeds (P &gt; 0.05).
