Where do laboratory animals come from?

Rat breeding: mother rat with offspring.
Rat breeding: mother rat with offspring.  

Bayer obtains its laboratory animals almost exclusively from qualified breeders who are authorized specifically to breed laboratory animals. Without the appropriate official authorization, Bayer would not work with them. The breeders are also inspected by Bayer’s Animal Welfare Officer. The farms are also monitored continuously by the relevant veterinary authorities.






Only in the following exceptional cases does Bayer depart from this tried-and-tested procedure:
  • Where no official breeders exist for agricultural livestock and fish. Bayer obtains these animals from selected agricultural farms and fisheries – an exception expressly permitted under the German Animal Welfare Law.
     
  • Bayer breeds a small number of its own animals. These are mainly genetically modified (transgenic) mice.
