Early detection of mastitis: technologies and benefits for livestock farming

What mastitis is and why it must be promptly addressed

Bovine mastitis is one of the most common and costly diseases in dairy cow farms. It is an inflammation of the mammary gland that compromises both the quantity and quality of the milk produced.

When the somatic cell count exceeds 200,000 cells/ml (an indicator of subclinical mastitis), up to 180 kg of milk per lactation can be lost. Besides the production drop, mastitis reduces lactose content (by up to 20%) as well as fat and protein levels, negatively affecting cheese production and the economic value of the milk. Each case of mastitis also involves veterinary costs, additional labor, and premature culling of the affected cows.

The benefits of early mastitis diagnosis

Identifying mastitis in its early stage allows to:
• Intervene promptly by isolating the animal and starting targeted therapy;
• Reduce production losses;
• Limit the spread of infection within the herd;
• Decrease antibiotic use;
• Improve animal welfare and the productive longevity of the cows.

Modern technologies for early mastitis detection

Milk electrical conductivity sensors

During milking, sensors integrated into the system measure the electrical conductivity of the milk from each quarter. Out-of-range values indicate ionic changes related to inflammation and increased somatic cell counts. The data are recorded in real time and can signal subclinical mastitis even before obvious symptoms appear.

Optical detectors for clots and blood in milk

These devices, positioned along the milking lines, detect the presence of clots or blood, signaling clinical cases of mastitis. The systems trigger immediate alarms and prevent contaminated milk from being mixed with healthy milk.

Automated somatic cell counting

Inline analyzers or portable devices allow precise measurement of the SCC (Somatic Cell Count) during each milking. This enables the detection of subclinical mastitis and monitoring of mammary health trends over time.

Collars and sensors for animal health

Smart collars and pedometers track behavioral parameters such as motor activity, rumination, food intake, and temperature. Variations can early signal inflammatory states like mastitis. The systems generate alerts and enable targeted animal monitoring.

Benefits of early mastitis detection for livestock farming

Reduction of production losses

Early diagnosis and timely treatment reduce the production decline associated with mastitis and preserve the qualitative parameters of milk (fat, protein, lactose).

Higher milk quality and quality premiums

Keeping the SCC low in bulk milk ensures higher quality milk, suitable for processing and rewarded by dairies.

Lower veterinary expenses and reduced drug use

Targeted and early treatments limit antibiotic use and reduce the need for complex interventions, lowering overall healthcare costs.

Improvement of welfare and fertility

Cows treated promptly suffer less, remain healthier and more fertile, and maintain high reproductive and productive performance.

Support for management decisions

Thanks to data collection and analysis, it is possible to identify recurring patterns of mastitis onset and intervene in routines and facilities to improve prevention.

Consclusions

Early detection of mastitis, enabled by sensors and automated systems, today represents a strategic ally for dairy farms. It protects herd health, ensures product quality, and improves the farm’s economic efficiency. Investing in these technologies means choosing a smarter, more sustainable, and competitive management model.
