Equine Care API
Horse-care maths as an API, computed locally and deterministically — the everyday numbers a horse owner, barn manager or vet tech runs without reaching for a chart. The weight endpoint estimates body weight from a weight-tape measurement using the classic formula weight ≈ heart girth² × body length ÷ a type divisor (adult 330, yearling 301, weanling 280, pony 299) with measurements in inches — a horse with a 72-inch girth and 66-inch length comes out at about 1,037 lb (470 kg), the number you actually dose wormer and feed against. The feed endpoint turns body weight and a goal into daily forage: horses eat roughly 1.5–2.5 % of body weight in dry-matter forage a day, so a 1,000 lb horse on maintenance wants about 15–20 lb of hay, more to gain and less to slim. The gestation endpoint gives the foaling due date and the normal 320–362 day window from a breeding date — a mare bred on 1 April is due around 7 March the next year, give or take three weeks. Everything is computed locally and deterministically, so it is instant and private. Ideal for barn-management and horse-care apps, breeding and foaling trackers, feed-calculator and tack-shop sites, and equine-vet tools. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational estimates — not veterinary advice.
