Analysis Of New Bovine Sex Selection Technology Through Ivf Test
Dongku Kim et al.
Objective: We have developed a new monoclonal anti- body protein to separate the bovine X- and Y- sperm. Using this protein, we make new bovine sexing product, WholeMom-Bo- vine sperm sexing kit (WM-B) (NuriScience Inc. Seoul, South Korea). In genera
In this study, we investigate the developmental efficiency and sex ratios of IVF embryos produced with conventional fro- zen bovine semen straw in comparison with WM-B treated fro- zen semen straw or frozen WM-
