Abstract

Successful sex-sorting of goat spermatozoa and subsequent birth of pre-sexed kids have yet to be reported. As such, a series of experiments were conducted to develop protocols for sperm-sorting (using a modified flow cytometer, MoFlo SX®) and cryopreservation of goat spermatozoa. Saanen goat...

Abstract

Flow cytometric sorting for the preselection of sex has progressed considerably in the 20 years since its inception. This technique has allowed the production of pre-sexed offspring in a multitude of species and become a commercial success in cattle around the world. However, due to the stress...

Abstract

Seminal plasma purportedly plays a critical role in reproduction, but epididymal spermatozoa are capable of fertilisation following deposition in the uterus, calling into question the biological requirement of this substance. Through a combination of direct observation of spermatozoa in utero using ...

Abstract

New nonsurgical procedures for inseminating swine with a low number of spermatozoa have been developed and/or evaluated over the last few years. These procedures allow the deposition of the insemination dose into the uterine body (post-cervical insemination) or directly into the uterine horn (deep...

Abstract

Artificial insemination (AI) of swine is widely practiced in countries with an intensive pig production. It is a very useful tool to introduce superior genes into sow herds, with minimal risk for disease transmission. However, the impact of semen that is contaminated with pathogens can be enormous. ...

Abstract

Sex-sorting of mammalian spermatozoa has applications for genetic improvement of farm animals, in humans for the control of sex-linked disease, and in wildlife as a captive management strategy and for the re-population of endangered species. Considerable research has been undertaken worldwide on...

Abstract

Despite being developed in its present form 20 years ago, sex-sorting of mammalian sperm is still a work in progress. While relatively successful in cattle and sheep, the unique challenges of incorporating sex-sorted sperm into pig production have not yet been overcome. Generally speaking, boar...

Abstract

Although cryopreserved boar semen has been available since 1975, a major breakthrough in commercial application has not yet occurred. There is ongoing research to improve sperm survival after thawing, to limit the damage occurring to spermatozoa during freezing, and to further minimize the number...
