Breeding season — mare side
Track a mare from heat cycles through breeding, pregnancy checks, foaling, and progeny — all on one connected timeline.
For a broodmare, HorseBook follows the whole season on her profile: heat cycles, the breeding itself, pregnancy checks, the foaling, and the foal that results. Each cover flows into a pregnancy and then a foaling, drawn as one connected timeline, so a mare's reproductive history reads top to bottom instead of scattered across separate lists.
Open a mare and go to her Breeding tab to find all of it. (Geldings don't get breeding tools, and stallions get the stallion side instead.)
Heat cycles
Log a mare's cycles as you track her — dates, and the details your vet gives you like follicle size, uterine edema, ultrasound and palpation notes. It's the running record you look back on when you're deciding when to breed.
Recording a breeding
When she's covered or bred, log it with the method:
- Live cover — by hand or at pasture
- Artificial insemination — fresh, cooled, or frozen semen
- Embryo transfer
- ICSI
You can note the stallion, the date, and — for AI — the semen's shipping condition. That breeding date is what everything downstream counts from.
Pregnancy and checks
Once she's confirmed in foal, a pregnancy status card rides at the top of her Breeding tab — where she is, how long along, and the due window counting down. Log each pregnancy check your vet does with its result — positive, negative, or recheck — and how many days along she was. HorseBook tracks the checks so you can see the pregnancy hold across the season.
If a mare loses a pregnancy, you can mark it, and the record reflects it honestly rather than pretending the season's still on.
How the due window works
A horse pregnancy runs about eleven months, and no foal reads a calendar. HorseBook builds a window off the breeding date rather than one hard date — an early edge, an expected date, a normal-range end, and an overdue mark — and surfaces the window as foaling approaches so you know when to start watching. It's a planning aid, not a prediction; your vet's read is the one that counts.
Foaling
When she foals, record it: the date, the foal's sex (colt or filly), presentation (normal, or the ones you hope not to see — breech, dystocia, red bag), and the early-care details you and your vet track, like IgG. Recording the foaling closes out the foaling window on your calendar.
Progeny
The foal can become its own horse in HorseBook, linked back to the dam (and sire) so the family tree connects. From there it's a full profile like any other — its own records, photos, and someday its own breeding history.
Both web and iPhone
The full mare workflow — cycles, breeding, pregnancy, foaling, progeny — is on the web dashboard and the iPhone app, and it syncs. Log a pregnancy check from the barn aisle; it's on the web that evening.
