• Animal Health

People throughout the world have close relationships with their pets, which are often treated as part of the family and keep their owners company into old age. Farm animals are suppliers of food, on which high demands are made in terms of quality. Our aim is to protect and preserve the health of animals with our products. We know the needs of our customers – whether veterinarians, pet owners or farmers.

The role animals play in our lives is growing in significance, and as humans and animals live closer together, it has also become more necessary to protect humans from the transmission of disease pathogens. Bayer has secured a leadership position in researching and developing products for animal health and pest control since 1919, and we are constantly developing new, better products and improved forms of administration for the benefit of the animals in our lives.

Our Advantage™ product family for flea and tick control has been a market leader for years. One of the fastest- growing products in this area is our innovative Seresto™ collar. When animals fall sick, we can help with a range of treatment options, especially for bacterial infections.

Farm animals, fish and bees supply foods such as milk, eggs, fish, meat and honey. Their health is therefore of special importance for humans. For this reason our portfolio includes products both for treating sick animals and for preventing disease occurrence.

To this end, Bayer offers veterinarians and farmers innovative medicines and solutions that contribute to the quality of life, health and well-being of farm animals around the world. Among the important areas are in the treatment and prevention of parasitic diseases, anti-infectives, pharmacological therapies and farm hygiene. We also have an ongoing quest to discover and develop new and innovative therapies to make the world a better place for animals and humans.

Diseases cause pain and suffering in animals, too. We support animal owners in preventing pain or ensuring responsible treatment. We also participate in animal welfare projects worldwide, including one to protect mine detection dogs in Cambodia.

30 million

companion animals are treated with our products each year to protect them from external parasites – as are 25 percent of farm animals.


Our goal at Animal Health is to strengthen our leadership position in the companion animals market and achieve profitable growth in the livestock market. We aim to achieve this by expanding our research and development activities and through selective in-licensing and acquisitions.
