Nutrivert is developing replacements for antibiotics in livestock production, the largest pharma market on earth.


At Nutrivert, we’re developing replacements for livestock antibiotics, the largest-volume pharma market on Earth. Total livestock antibiotic sales are worth $4.7 billion annually, of which an estimated $3.7 billion is used at least in part to promote livestock growth.


Consumers and regulators object to this use because multiple studies show that livestock antibiotics select for resistant strains of bacteria which then jump from animals to humans. At Nutrivert, we’ve solved the 70-year-old mystery of how antibiotics, even when given at doses too low to cure disease, still promote livestock growth.


We have over 50 years’ experience working with blockbuster animal drugs, including Ivomec, Heartgard, Frontline, and Nexgard. Now we’re developing non-antibiotic replacements for this $3.7 billion global market.
