Sperm cells are the endpoint of male spermatogenesis and have particular anatomic and
metabolic features. Sperm cryopreservation and storage currently require liquid nitrogen or …

Building on the successful structure of the first edition, the second edition of Reproductive
Technologies in Farm Animals has been totally updated and revised to provide an up to date …

Pregnancy rate following artificial insemination (AI) in sheep is variable depending on
several factors. The Churra breed (milk breed of the North-West of Spain) yields lower …

In sheep, artificial insemination serves as an important technique for breed improvement. In
this context, genetic material from a small number of superior sires can be used in a large …

In this study, two following experiments were performed to improve post-thaw motility and
viability of frozen-thawed ram spermatozoa. We examined i) the effects of different …

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

The objective was to evaluate the effects of various antioxidants and duration of pre-freezing
equilibration on cryopreservation of ram semen. Semen samples from four rams were …

Contents Artificial insemination in ram is scarcely widespread comparing with other
domestic species. This has been due not only to fertility results being irregular and low but …

In the last few decades, farm animal genetic diversity has rapidly declined, mainly due to
changing market demands and intensification of agriculture. But, since the removal of single …

A detailed examination of the cervical canal in the ewe was carried out. This analysis could
be used to design new catheters for artificial insemination (AI) to achieve deeper cervical …
