KUBUS was founded in 1986 and is distinguished by having developed the first commercially available long term and high protection boar semen extender, MRA®, thus revolutionizing the practice of artificial insemination (AI) in pigs, which until then was in its infancy. Since KUBUS’ origins in 80’s, the company has been characterized by being heir to the great work carried out by the distinguished researcher and KUBUS’ its founder, Dr Santiago Martin Rillo. In addition to developing the technology for the conservation of semen, he carried out the essential task of disseminating knowledge and know-how of assisted reproduction techniques and reproductive management in pig farms. With this, he greatly contributed to the standardization and globalization of swine AI techniques at an international level.
