These types of Swine Gestation Calendars required you to count the days til your pig’s due date. google_ad_width = 234; if(month < 10) var newdate = new Date(date); // } Pregnancy Gestation Calculators for Helping You Estimate Pregnancy Due Dates. Also, try using any of our other gestation calculators just for fun! var now = new Date(); $('#txtDate').datepicker({}); var date = new Date(tt); var day = now.getDate(); It is wise to keep the animals separated by a fence or other barrier so that AI can be conducted without interference from the boar. amzn_assoc_tracking_id = "gestcalc-20"; If no boar is located on the farm, commercial aerosol sprays that mimic boar odor are available. amzn_assoc_region = "US"; Having an active, mature boar to help with heat checking is the best way to determine standing heat, but is not possible at every farm, especially when Artificial Insemination (AI) is practiced. Standing heat can last two days and breeding can occur every 12 hours during this time. *Uses an average 114 day gestation period for a Pig. It uses a 63 day gestation period for swine. Sows will not always conceive after one breeding. The Gestation Period for Pigs is approximately 112-115 days from the first breeding. All Rights Reserved.

} amzn_assoc_ad_type = "smart"; After weaning, sows will come into heat again as quickly as 3 days but 4-7 days is more typical with an average return to heat of 5 days after weaning. This allows manager observation and oversight of natural matings. var tt = document.getElementById('txtDate').value; The Swine Gestation Calculator above attempts to generalize the approximate due date. Piglet Due Date.


"); document.getElementById('txtReturnDate').value = someFormattedDate; jQuery(document).ready(function($) { var mm = newdate.getMonth() + 1; Take notes on each sow as they begin to exhibit signs of heat and check them every 12 hours until true standing heat is attained. amzn_assoc_marketplace = "amazon"; Knowing both non-heat behavior and heat behavior makes it easier to identify when a female is coming into heat and when they reach standing heat.

Nose-to-nose exposure to a boar will introduce the female to pheromones in the boar’s saliva and greatly enhance heat determination and breeding success. Did you know that bristly hair from swine are often used for brushes. This can be used to help synchronize farrowing dates in small herds so that animals are farrowing around the same time, and can be weaned of piglets (and therefore bred for their next litter) at the same time. Pig Gestation Table / Chart. Females that are receptive to the boar are most certainly in heat, but constant mingling of the animals can lead to female injury due to aggressive maneuvers of the often-larger boar. An easy way to remember this is “3 months (90 days), 3 weeks (21 days), 3 days” (90 + 21 + 3 = 114). A common reason for failure is breeding females before they are in a true standing heat. The swine gestation period is anywhere from 112-115 days.. Farrowing Calculator. //-->

Our farrowing calculator in no way should take away from the need for you to seek a vet.

var today = month + '/' + day + '/' + now.getFullYear() ; if(day < 10) Sows and gilts have an average 21 day heat cycle, although this can range from 17 to 25 days. /* 234x60, created 4/1/11 */ The Pennsylvania State University, 323 Agricultural Administration Building, University Park, PA 16802, Swine Production and Management Home Study Course.

You can use the printable swine or pig gestation table or chart below to determine when your pregnant sow will give birth (farrow). This can be used to help synchronize farrowing dates in small herds so that animals are farrowing around the same time, and can be weaned of piglets (and therefore bred for their next litter) at the same time. Often the female’s ears will be in an erect position during standing heat.

var someFormattedDate = mm + '/' + dd + '/' + y; });

amzn_assoc_ad_mode = "search"; //else{

The Farrowing Calculator is a much simpler process to use than the customary Swine Gestation Chart. Ideally, breeding occurs during a time called ‘standing heat’ during which time the female will ‘lock up’, meaning that she will exhibit a natural behavior of standing rigidly and be receptive to mounting of a boar.

Applying pressure to the back of the animal to see if she will stand rigidly is the most common manner to check for standing heat.

//if (newdate.valid()==true { With proper heat detection two or three matings are possible. This periodic exposure assures that heat responses occur during manager observation and not when you are away from the pigs. month = "0" + month; Please send any questions you may have to askabreeder@gmail.com.
