Automated In-Line Mastitis Detection

Bovonic, a New Zealand dairy-tech company, has developed in-line sensors that detect mastitis — the most costly dairy disease globally — during routine milking by analyzing changes in milk composition, somatic cell counts, and electrical conductivity in real-time. The system identifies subclinical infections before visible symptoms appear, enabling targeted treatment of individual cows rather than herd-level antibiotic administration. Bovonic is part of the emerging NZ precision dairy technology ecosystem alongside AIMER and Halter.

Mastitis costs the New Zealand dairy industry approximately NZ$280M annually through reduced milk production, veterinary treatment, discarded milk (antibiotic withdrawal periods), and somatic cell count penalties from processors. Subclinical mastitis — infection without visible symptoms — is particularly costly because it goes undetected until it affects bulk tank milk quality. Real-time detection at the individual cow level enables early intervention that preserves milk quality and reduces antibiotic use.

The technology aligns with growing consumer and regulatory pressure to reduce antibiotic use in livestock, particularly in export markets (EU, Japan) that impose increasingly strict residue testing. For New Zealand, where dairy exports represent approximately 25% of goods exports, protecting milk quality through technology rather than prophylactic antibiotics is both an economic and market-access imperative.
