Artificial insemination
Sperm sorting by flow cytometry is an established technique in veterinary practice, and in the dairy industry most female cows are artificially inseminated with sorted semen to increase the number of female calves (using sperm sorting is less common in other species of farm animals, however artificial insemination is common). Artificial insemination of farm animals with sorted sperm is recognized by the Food and Agriculture Organization (FAO) as a promising way of increasing efficiency of agriculture needed to produce enough food for the growing human population. Utilizing artificial insemination with sorted sperm is seen as a way to create an optimal ratio of male and female calves to increase dairy milk production.
