When do teets begin filling?

This will be Ms. Piggy's third litter. Reading on the net, it appears as her teets should start filling 3-4 days before she delivers. I can't remember when she began filling with the first two litters. I had tagged her due date at April 6th but her teets began filling today. I'm soooo confused!!

Her teats will begin filling 3-4 days prior... However, she will be letting milk down (you will be able to milk her) 10-12 hours prior to labor.

Do not mistake bag filling with their bellies dropping, some older sows have a natural sag to their teet area, so as their uterus expands their sack keeps dropping; if the area feels firm but not hard then it is filling.

It can appear as though the teats are enlarging as much as three weeks prior to farrowing. The 10-12 hour mark for milk expression is the single most accurate indicator ime though.

The teats will seem to elongate and then the udder will begin to fill. As others said, the teats themselves don't begin to have any milk in them until 3 to 4 days prior...you will get only drops of milk if you try to express some. You will get a good stream of milk within 12 hours of farrowing.

That is what I had understood. She's in with a new boar and I had her due date on April 6th. Maybe he's just uhmmmm faster than normal.... I'd better get some of her "home improvements" done this weekend. Her teets are definitely larger today than yesterday.

it can happen up to a week before they deliver ... i have been watching mine carefully.

I have 4 berk gilts that are bellied to the ground and are due the earliest of March 29th. As long as you know the due date, pigs are RARELY off more than 1 or 2 days.
