Semen processing and artificial insemination in health management of small ruminants. (Special Issue: Reproductive health management of sheep and goats.)

摘要

Artificial insemination has changed the small ruminant industry and has allowed increased genetic improvement, better control of reproduction and sexually transmitted diseases, dissemination of valuable genetics and preservation of the genetics of endangered breeds. Recent developments in this technology have focused on preserving the vitality/fertilizing capability of fresh and frozen spermatozoa by improving the composition of extenders, and by changing cooling/freezing protocols. The other main issue is the development of minimal invasive techniques for proper deposition of fresh or frozen semen. The paper discusses state of the art in methodology and technology currently used in small ruminant artificial insemination, as well as future perspectives after their wide application in these animal species.
