A sexually mature female pig in good health should cycle every 3 weeks if she is not pregnant or lactating. (The estrous cycle of swine lasts approximately 21 days.)Pigs are ready to breed when they are 8 months old, weigh 300 pounds and are in standing heat. This is a quick checklist for you. You need to have all four things before breeding the gilt! Most breeding stock pigs are ready to breed at 8 months of age. This will give you a first litter at one year of age for the gilt.

How do I know when my pig is in heat?
Vulvas of pigs nearing heat may be swollen, red, and discharge mucus. 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. Often the female’s ears will be in an erect position during standing heat. Her tail may also move to expose her vulva.
How long does a pig go into heat?

An easy way to remember this is “3 months (90 days), 3 weeks (21 days), 3 days” (90 + 21 + 3 = 114).
What is heat detection in pigs?
