BioWorma Now Available

BioWorma® can now be purchased in the US. Previously, livestock producers could only purchase Livamol, the supplement that contains BioWorma®. This is because EPA restricts the sale of BioWorma® to veterinarians and feed premixers.

The ACSRPC is a group of scientists, veterinarians, and extension specialists dedicated to helping small ruminant producers control GI parasites in their flocks and herds.
