Best Sire Genetics was established in the year 2014. Best sire genetics deals in all type of frozen animal semen. Semen in the early days of artificial insemination was delivered every day as semen was not frozen at this point. In the 1960s the Robert Cassou invented a package in France that utilized a plastic straw. This straw was made of PVC material and had two cotton plugs with powder in-between them. Since then the technology has advances and today we are in a position to produce top quality semen to genetically improve the quality of the offspring.
