Well just for you Jay I went and slapped on the gloves and grabbed Big Momma. She's the larger of the two breeding ASF females I have right now and she is as of tonight 103 grams (she's likely pregnant just not heavily so at the moment).
Here's a picture with a dollar bill for comparison. Sorry for the poor quality of the picture but this is the best I can do with the fast moving little boogerheads LOL.
So basically an adult breeder ASF in good body weight is about 2.5 times the weight of an adult mouse I would say. The ones I feed off are less than this size though but I'm not going to try and catch one of those wigglers for a picture or weight LOL.
