Nutrivert announces first close on $6 million Series A-2 funding round
April 17, 2026 - Nutrivert Inc., a developer of non-antibiotic replacements for antibiotic growth promoters in livestock, today announced it has completed the first close, raising $2.375 million, of its Series A-2 funding round of $6 million. The round was led by global animal health investor Arrow Ventures with participation from other investors. The funding will be used to further develop Nutrivert’s manufacturing, human food safety and target animal safety and efficacy packages for the company’s lead product Nutrivert LDPP.
Nutrivert LDPP is a proprietary, novel, orally available, lipidated synthetic enantiomeric desmuramyl analog of muramyl dipeptide, the smallest conserved immunoactive component of bacterial peptidoglycan. LDPP has no antibacterial effect but has consistently promoted growth and improved feed efficiency in pig studies. LDPP binds to the mammalian NOD2 receptor and is the only NOD2 ligand reported to inhibit the inflammatory signal NF-κB. In pilot studies, LDPP rescued 70kg pigs from an otherwise lethal dose of porcine reproductive and respiratory syndrome virus (PRRSV) and abrogated influenza disease symptoms in piglets.
The Company intends to develop LDPP for all major livestock species worldwide. Patents have been granted in most major markets.
The global antibiotic growth promoter market is worth an estimated $5.8 billion. Approximately 73% of all antibiotics are fed to livestock. The market is believed to be the world’s largest drug market by volume, with ~100,000 tons of active pharmaceutical ingredient administered annually. FDA’s latest data, for 2024, show a 13% rise in U.S. livestock antibiotic use since 2017. The Food and Agriculture Organization reports that livestock antibiotics are mostly given to speed animal growth. Regulators and non-governmental organizations have called for reduction of antibiotic use in livestock, citing concerns that the global, intensive use of antibiotics, often at subtherapeutic doses, selects for antimicrobial resistance: bacteria that are “immune” to antibiotics and that therefore pose a threat to public health. Spillovers of antibiotic-resistant bacteria from livestock to humans have been documented.
“Nutrivert LDPP has consistently improved feed efficiency in pigs without antibiotics,” said Bernhard Kaltenboeck, CSO. “We are excited to have the support of Arrow Ventures and our other investors in bringing a new tool that will help producers reduce production costs and reduce selection pressure for antimicrobial resistance.”
