Predicting New Life with Precision
Successful livestock and pet breeding requires meticulous record-keeping. Our Animal Gestation Calculator helps you estimate the due date of your animals based on the date of service or conception, using species-specific averages.
Gestation Periods at a Glance
- Cattle (Cows): Average 283 days.
- Horses (Mares): Average 336 days.
- Sheep/Goats: Average 150 days.
- Dogs/Cats: Average 63 days.
- Swine (Sows): Average 114 days (3 months, 3 weeks, 3 days).
Factors Influencing Due Dates
While averages are helpful, several factors can influence the actual birth date:
- Litter Size: Larger litters in dogs or pigs often lead to slightly shorter gestation periods.
- Breed: Different breeds within a species can have variations of several days.
- Seasonality: Environmental factors and day length can impact equine gestation.
