Abstract: | Sorting stallion semen into two separate populations of enriched X- or Y-bearing sperm can be done successfully. For this, stallion semen can be shipped to a sorting facility, but the mare must be in close to the sorting laboratory. Fertility rates when using 20-40 million sperm are an acceptable 60% per insemination. The procedure can be implemented in embryo transfer programs, with no deleterious effect on the pregnancy rate or embryonic death. |
