[HTML][HTML] Pregnancy rate and birth rate of calves from a large-scale IVF program using reverse-sorted semen in Bos indicus, Bos indicus-taurus, and Bos taurus cattle
Obtaining sexed sperm from previously frozen doses (reverse-sorted semen [RSS]) provides
an important advantage because of the possibility of using the semen of bulls with desired
genetic attributes that have died or have become infertile but from whom frozen semen is
available. We report the efficiency of RSS on the pregnancy rate and birth rate of calves in a
large-scale program using ovum pick-up and in vitro embryo production (IVEP) from Bos
indicus, Bos indicus-taurus, and Bos taurus cattle. From 645 ovum pick-up procedures …
