Germplasm storage and transportation in artificial insemination (AI) and other advanced
technologies are facilitated by cryopreservation. In reproduction, the cryopreservation of …

Semen was collected with an artificial vagina from four adult rams. The ejaculates were
pooled and diluted, using a split-sample technique, in four different extenders: one for milk …

Successful artificial breeding underpins rapid genetic and production gains in animal
agriculture. In sheep, artificial insemination with frozen semen is performed via intrauterine …

The ability of a range of extenders to cryopreserve ram spermatozoa was tested. The
extenders were modified by the inclusion of citrate, Tris buffer, trehalose, and EDTA …

In this study, certain enzymes in ram semen involved in reactive oxygen species elimination
and their changes during the cryopreservation process were characterized in order to …

The aim of this study was to evaluate the effects of lyophilized egg yolk extender on ram
semen cryopreservation. Ejaculates with a thick consistency, rapid wave motion (3–5 on a 0 …

The aim of the present work was to evaluate plasma membrane integrity, motility, vigor and
morphology of fresh and frozen goat spermatozoa with or without seminal plasma. Semen …

This study was carried out to investigate the effect of the semen freeze–thawing process on
the functionality and molecular structure of ram spermatozoa. The temperature of pooled …

Hu sheep is a valuable sheep breed in China, and semen cryopreservation of Hu sheep is
important for sustainable development of the agri-food industry. This study aimed to evaluate …

Simple Summary Sperm cryopreservation is an important step to optimize artificial
insemination protocols for rams. Traditionally, the improvement of ram sperm …
