Semen donor selection by in vitro sperm mobility increases fertility and semen storage in the turkey hen
Semen donor selection sperm mobility semen storage turkey hen
2009/2/17
Commercial turkey production relies on the artificial insemination (AI) of pooled semen. However, semen quality ultimately depends on the quality of individual ejaculates. The purpose of this stud...
Selection of acrosome-reacted sperm with MH61-immunobeads
acrosome-reacted sperm MH61-immunobeads
2009/2/12
Separation of acrosome-reacted viable sperm is an important problem in the analysis of sperm function and the micromanipulation of gametes such as the microinjection of sperm into ooplasm and subzon...
