AI Heat Detection for Dairy Farms

Know the 12-hour window. Stop missing heats.

Ovum reads your activity collars and cycle records to tell you exactly when each cow is ready to breed, so you stop guessing and hit your 6-week in-calf rate.

What Ovum Does

Activity collar data plus cycle memory, exact timing

Ovum connects to your existing activity collar system and reads the motion data your cows are already producing. It combines that with each animal's individual cycle history to build a per-cow breeding model.

As each new cycle completes, the model gets sharper. When a cow approaches her fertile window, Ovum sends you a push notification, SMS, or email alert, with the exact window open and close times and a confidence score.

No new hardware. No population averages applied to individual animals. Just a clear alert telling you which cow, which paddock, and how long you have.

Capabilities

Built for herd managers, not for dashboards

Three capabilities that work together to stop you guessing at heat detection.

Per-cow cycle model

Ovum builds a separate reproductive model for each animal in your herd. Not population averages, not breed averages, but the actual cycle length and variation pattern of cow 214 specifically. The first calibration period takes 1-3 cycles. After that, predictions tighten with every new event recorded.

Detection accuracy, same herd, same collars

12-hour alert window

When a cow's fertile window opens, you get a push notification, SMS, or email with the window open time, window close time, and a confidence level. A closing alert fires at the end of the window. You act on clear information, not guesswork at 3am.

Herd breeding calendar

A visual monthly calendar showing upcoming predicted windows and recorded breeding events, per mob. Plan your AI technician visits around predicted cluster events rather than reacting to missed ones. Works for mixed herds with different cycle patterns.

What herd managers say

I used to set phone alarms for every two hours through the night during peak breeding season. Now I get one alert when the window opens and another when it closes. We went from 49% conception to 67% in four months, which I honestly didn't think was possible with the same collars we already had.

The difference with Ovum is that it stopped treating all my cows the same. Cow 87 has a 19-day cycle, cow 43 runs 23 days. When the system knew that, the alerts got accurate fast. After the second cycle with good data, I trusted the predictions. We haven't had a missed heat in the paddock in six weeks.
