The Swine Gestation Calculator or Swine Pregnancy Calculator is used to calculate swine pregnancy.
With the Gestation chart, you had to count the days until your Swine’s due date.
Swine Gestation Calculator helps to answer the questions: ‘What is a Swine’s due date?’ or ‘How Long Are Swines Pregnant For?’ or ‘How Long is a gestation period for Swine?’.
It’s important that you enter the 1st day your Swine was bred for it to work properly.
The Gestation or pregnancy Period for Swine is approximately 112 to 115 days from the first breeding.
Steps To Calculate Swine Pregnancy Due Date
Enter the First Date of Swine Mating
Check the Swine's Estimate Delivery Date
Check Min & Max Delivery Date
Swine Gestation Calculator Formula
The Swine Gestation calculator uses the following formula:
Date of Farrowing = Mating date + 114 days
Calculate Swine Pregnancy
The Swine Pregnancy Calculator is a much simpler process to use than the customary Swine Gestation Chart.
Sometimes it’s been called the Swine Gestation Calendar.
These types of Swine Pregnancy Calendars required you to count the days until your Sow’s due date.
This swine gestation calculator is no way to take away from the need for you to seek a vet.
Their pro advice about your swine’s gestation period is invaluable.
There are many items a properly licensed, pro vet will notice about needed care for your swine.
Did you know the bristly hair from swine are often used for brushes?
Did you also know swine meat accounts for 38% of worldwide meat production?
Another interesting fact is older swine will consume three to five gallons of water per day.
Gestation Period for Swine
The Gestation Period for Swine is approximately 112-115 days from the first breeding.
Sows (Female Swine) will not always conceive after one breeding.
Hogs will generally mate multiple times in one cycle.
The Swine Gestation Calculator above attempts to generalize the approximate due date.

Pig Gestation Calendar
Some animals breed during spring, some during summer, and, for others, the season doesn't matter.
Pigs belong to the latter. Pigs reach sexual maturity at 5 to 6 months old and then experience heat every 18 to 24 days.
If you keep a male and female pig together for more than 24 days, there is a high probability that they have bred, and the sow is pregnant.
Pigs can give birth from one to even 20 or more piglets.
On average, the fourth litter is the biggest one.
Both litter size and gestation period depend on the sow's genetics, age, environment, nutrition, weight, and parity.
The most obvious sign that a sow is pregnant is that she doesn't go into heat after an appropriate number of days.
Other much less noticeable signs are physical changes in the belly shape and weight gain.
Near the farrowing date, the sow will act restless and begin to nest.
How Long are Pigs Pregnant?
The gestation period in pigs is 112 – 115 days from the first day of mating.
They have an average gestation period of 114 days.
