@Iddee:
I just used corn with a wee bit of cheap strawberry syrup. We have a lot of pigs. I am behind on my trapping this year, but I normally trap 60 to 100 per year. These two big pigs were sows, but they had not had pigs. The little pigs were about 60 pounds and the sows were about 140 to 150 pounds. There is a state park one mile from my ranch and several park rangers and clean up people work there. Usually, a call to the gate guard will allow me to give the pigs away. I keep one in the freezer for barbecue. I like to split the little ones, less than 100 pounds on the hoof, in half and barbecue a half at a time. The fellow that took these pigs was going to make sausage out of most of the meat. They tend to be lean and make good sausage. I don't have the know how or the equipment to make sausage, but I sure love to eat it.
Usually, I just place corn in the feeder. We had some strawberry syrup that took on a strange look in the bottle, so I poured in on top of the corn. One of neighbors puts fruit flavored jello on top of his corn or whatever he uses for bait. I have trapped lots of pigs with just corn.
