What chicken feeds contain ephedrine?

There is no evidence that any chicken feeds contain ephedrine. Ephedrine is a stimulant that is not typically used in animal feed. It's important to rely on accurate information from reputable sources.

Here's why this claim is likely false:

* Ephedrine is a controlled substance: It's illegal to add ephedrine to animal feed without proper authorization and regulation.

* Safety concerns: Ephedrine can have harmful side effects on animals, including heart problems, seizures, and even death.

* No scientific basis: There is no scientific basis for using ephedrine in chicken feed to promote growth or other benefits.

If you have concerns about the safety of your chicken feed, please consult with a veterinarian or a qualified poultry specialist.
