6. Boehringer Ingelheim Vetmedica - Top 10 animal health companies

Boehringer Ingelheim Vetmedica
2013 Revenue: $1.8 billion
HQ: St. Joseph, MO

Boehringer Ingelheim's animal health unit, Vetmedica, worked hard to pull in total revenue of about $1.8 billion last year. The St. Joseph, MO-based operation made strides in the animal vaccines arena in 2013, releasing its FLEXCombo for swine in September and its new Vetera XP line of vaccines for horses the following November. This year, product launches are still going strong: Vetmedica launched another swine vaccine in April and then its Fel-O-Vax, a vaccine for cats with 50% less volume per dose, in May. Vetmedica said in last year's earnings report that its top-selling animal health products are its swine vaccines Ingelvac Circoflex and Ingelvac PRRS, as well as Metacam--a joint pain medication for dogs--and Duramune, the company's canine vaccine. Just this month, Vetmedica got approval in Japan for its telmisartan treatment for chronic kidney disease and renal failure in cats. -- Justin Heifetz (email | Twitter
