Sexed sorted semen in Dairy Industry

For many years, animal scientists and livestock owners have dreamed of having a calf of their desired sex. In the case of cows, pre-conception selection for a particular sex is typically economically justified. Due to the mechanisation of agriculture, male cows are raised by livestock owners less frequently, and when they do, the animals are either slaughtered—which is illegal in the majority of Indian states—or left to starve to death. So, we can use sex-sorted semen technology to protect ourselves from this unusual predicament of having "unwanted" male calf born (Gaur et al., 2020). Sexed semen, also called Gender Enhanced Semen (GES) has been commercially available in the Indian dairy industry for approximately six year.This technology is being used on a limited basis, and there seems to be considerable interest in this new tool on dairy farms. There was no reliable way to identify the sex of sperm cells before the 1980s. At the Lawrence Livermore National Laboratory, Dr. Daniel Pinkel created the first sperm sorting technology. Additionally, Dr. Pinkel created the first flow cytometer. Researchers from Oklahoma State University and Lawrence Livermore National Laboratory showed that flow cytometry could distinguish between X and Y sperm based on changes in DNA content (Loggan, 2019). The system was later patented under the name “Beltsville Sperm Sexing Technology,” and in 2001 Sexing Technologies (ST), Texas, acquired a licence to utilise it commercially in the United States. In many European states, the USA, Canada, Mexico, Brazil, China, and Japan, among others, Sexed semen now commercially produces sex-sorted semen.
