A health calendar for polo horses: vaccines and deworming

In a polo horse breeding operation, health work is the quiet routine that holds everything else up: a herd current on vaccines and deworming performs better, travels without paperwork trouble and avoids losses that cost dearly. The challenge isn’t knowing what to do — your veterinarian defines that — it’s making sure nothing slips when you’re managing dozens or hundreds of horses.

This guide covers the typical checks in a breeding operation and a method to keep due dates from depending on anyone’s memory.

Important: the intervals below are indicative and vary by region, the animals’ age and each farm’s management. Your definitive calendar should be set by your veterinarian.

The usual checks

Equine infectious anemia (EIA): the Coggins test is required for moving horses, and is typically renewed every 60 days for horses that travel, or less often for those that stay on the farm.
Equine influenza: periodic vaccination, usually every six months, and required for transport and competition.
Encephalomyelitis: annual vaccination in most health plans.
Deworming: rotating dewormers every 60 to 90 days depending on parasite load, age and pasture management. Foals usually need a more frequent schedule.
Tetanus and other vaccines: according to the plan your veterinarian defines for your region.

The real problem: scale

With five horses, a notebook is enough. With sixty, the health calendar becomes a matrix of hundreds of constantly renewing dates: each horse has its own last-application date, and each type of check its own interval.

That’s where notebooks and spreadsheets fail: they don’t warn you. The due date you don’t see is the one that slips — usually discovered days before a transport, when renewing a Coggins in a hurry complicates all the logistics.

A method that doesn’t rely on memory

The principle is simple: record every application with its date, per horse, the moment it happens — at the chute, not that night at the office. Everything else follows from that record:

Define the interval for each health type once, for the whole operation (for example: deworming every 60 days, influenza every 180).
Record each application as it happens, on the horse’s profile.
Let the system calculate due dates per horse and show you what’s current, what’s coming due and what’s overdue.

In Polo Breeders this method comes ready-made: you configure the intervals at the operation level, record each application from your phone (it works offline, and with a microchip reader the horse’s record opens by itself when you scan it), and due-date alerts are calculated automatically. If your veterinarian has access to your operation, they record treatments directly while working the field.

The payoff you see at season’s end

A herd with its health current isn’t just peace of mind: it means organizing a transport without paperwork surprises, showing a complete history when selling, and making decisions (like holding back a mare or reinforcing a foal schedule) with data instead of recollections.
