Differential protein profile in sexed bovine semen: shotgun proteomics investigation.
The preparation of sexed semen is based on the differential DNA content between the X and Y chromosome bearing sperm cells determined by fluorescence-activated cell sorting. In spite of its intrinsic limitations this represents the only effective method. However, the employment of sexed sperm for breeding food producing animals on a large scale requires additional knowledge in the protein reper...
متن کاملEconomic opportunities for sexed semen on commercial dairy farms
Dairy farmers and others have been discussing the use of enriched X-bearing semen (sexed semen) for many years (Seidel and Garner, 2002). Sexing bovine semen is possible because X-sperm have 3.8% more DNA than Y-sperm. This difference can be identified with a flow cytometer by staining the sperm with a fluorescent dye that binds to the DNA. The technique is reasonably accurate (10% error rate) ...

متن کاملIn vitro and in vivo quality of bovine embryos in vitro produced with sex-sorted sperm.
In this work we analyzed the effects of three culture systems on developmental ability of bovine embryos in vitro produced with sexed sperm, the survival to vitrification (cryologic vitrification method) of such blastocysts, and their pregnancy rates after embryo transfer to recipients, both as fresh and after vitrification/warming. Finally, we measured the accuracy of the sorting protocol by a...
متن کاملApplication of sexed semen technology to in vitro embryo production in cattle.
Use of sexed semen in conjunction with in vitro embryo production is a potentially efficient means of obtaining offspring of predetermined sex. For thousands of years, livestock owners have desired a methodology to predetermine the sex of offspring for their herds. The ability to sort individual sperm cells into viable X- and Y-chromosome-bearing fractions made producers' sex selection dreams r...
