Abnormally Large Babies!

[Logandew]

Hi everyone,
I had a litter on Wednesday 7/5 to It's All Good on my Rollin Doubles gilt. She is 1.5 years old. She had 5 babies in her all weighing 4.75-5.5lbs, and 14"-16" long. She was due Tuesday 7/4. She was in labor for around 14 hrs. Had to pull everyone because they were just to big for her to pass. None them made it. She is fed the same amount as every other sow I have feed. Im just confused why these ones were so big? What do you think the reasoning could be to them being so big?

Thanks

Part of the reason is she only had 5 pigs in her. Fewer pigs usually correlates to bigger pigs at birth.
