Always in control of your herd with CowManager

Farmers are expected to produce efficiently, with optimal use of available resources, while maintaining high standards for animal welfare, fertility and productivity. CowManager enables dairy producers to stay in control by turning cow behaviour into actionable insight, the company says.

CowManager uses smart, reusable ear sensors that monitor cows 24/7. Whether the focus is on health, fertility, nutrition or the transition period, CowManager delivers continuous data, early warnings and clear decision support based on combining ear temperature with activity, eating and rumination behaviour.

The sensors are designed for long-term value. They are reusable, easy to activate and deactivate, and come with a lifetime warranty for as long as the subscription runs.

All technological upgrades are delivered over-the-air, meaning farmers always have access to the latest innovations without replacing hardware or incurring additional costs.

Fertility: Right moment, right decision

Missing a heat or inseminating at the wrong moment has a direct impact on herd profitability. CowManager’s Fertility Module ensures that this risk is significantly reduced.

By continuously analysing activity and rumination behaviour, the system identifies heats in real time and provides clear alerts for the optimal insemination moment.

The benefits are measurable:

• Fewer routine checks
• Structure insemination workflow
• Higher conception rates
• Shorter calving intervals
• Lower fertility-related costs.

Clear heat graphs and smart alerts also highlight irregular cycles or possible abortions, enabling early intervention and improved reproductive management.

Health: Early detection, healthier cows

Health issues often become visible only once productivity has already declined.

CowManager Health Module shifts this dynamic by detecting changes in behaviour at an early stage.

Subtle deviations, such as ear temperature drop, reduced feed intake or rumination time, or changes in movement patterns, are flagged before visual symptoms appear.

This allows farmers to act sooner, reduce the severity of disease and limit treatment costs. Early detection also contributes to better recovery monitoring after treatment, as behaviour data continues to provide insight into the cow’s condition.

Transition: Managing the most critical period

The dry-off and transition period remains one of the most challenging phases in a cow’s lifecycle, with 75% of all diseases occurring in this period.

CowManager Transition Module supports farmers by identifying cows at increased risk of health problems from up to 50 days before calving until 25 days after.

By monitoring changes in eating and rumination behaviour compared to the other dry-off or cows in transition on that farm, the system highlights animals that may develop issues such as milk fever or mastitis. This enables timely, targeted intervention and helps prevent transition-related diseases.

What comes out of it are healthier cows, fewer transition disorders and better control over dry period management, in/out group placements, lactation start and ration changes, say CowManager.

Nutrition: Insight that drives efficiency

Feeding strategy plays a central role in herd performance CowManager explains. CowManager Nutrition Module provides real-time insight into feed intake, group behaviour and heat stress.

This data allows farmers to optimise ration changes, prevent nutrition-related disorders and analyse behaviour patterns across different groups and periods.

By comparing groups and tracking trends over time, farmers can make informed decisions that reduce waste, improve feed efficiency and generate structural cost savings.

New: Youngstock Monitor – One sensor from calf to cow

The future of any dairy herd starts with healthy calves.

CowManager’s Youngstock Monitor follows calves from 14 days of age using the same ear sensor that later transitions automatically to the cow algorithm at 180 days.

Specially developed algorithms for calves and cows ensure that behaviour patterns are accurately interpreted at every stage of life. One sensor, from calf to cow, supports long-term herd development and contributes to a stronger, more profitable operation, CowManager claims.

Farmers can download the Calf Rearing Guide for practical insights into youngstock management.
