ベーリンガーインゲルハイム
In August 1997, Merial started as a joint venture between the animal health subsidiaries of Merck &amp; Co. (MSD AgVet) and Sanofi-Aventis (Rhône-Mérieux). Merial became the animal health division of Sanofi, when Sanofi bought out Merck's 50% share of the joint venture. On December 30, 2016 Boehringer Ingelheim completed a swap of their OTC business for Sanofi's animal health business. Merial is now owned by Boehringer Ingelheim and combined with their animal health business, Boehringer Ingelheim Vetmedica, to form Boehringer Ingelheim Animal Health.
