Avian Biologics Services
Testing, IgY Antibodies, & Custom Biologics
AVS Bio has been a trusted source of avian biologics and services for vaccine developers, diagnostics manufacturers, and research institutions since 1961. Our avian capabilities span serological, PCR and 9 CFR testing, IgY antibody production, and USDA-licensed custom biologics manufacturing, including For Further Manufacture (FFM) services — all supported by our own SPF-certified flocks housed in FAPP (Filter Air Positive Pressure) facilities.
Our avian services portfolio includes:
• Diagnostic & 9 CFR Testing — validated serological and molecular assays for poultry pathogen surveillance, SPF flock certification, and regulatory compliance testing.
• IgY Antibody Production — polyclonal IgY antibody production using our own high-yield SPF hens, with naïve immune system advantages for rapid, high-titer responses.
• Custom Biologics & FFM Manufacturing — USDA-licensed outsourced virus, antiserum, and bacterial antigen manufacturing, plus For Further Manufacture (FFM) split-manufacturing support for veterinary vaccine producers.
Whether you need a single diagnostic assay, a custom IgY antibody program, or a scaled biologics manufacturing partner, AVS Bio brings 60+ years of avian biology expertise to your project.
