Roundworms in Pigs

[bingo]

Hoping for some help/reassurance. I'm so paranoid about worms to begin with. We purchased our first pigs ever: two 7 week old feeder pigs in August. As soon as they were home we gave them a ivermectin injection, and put them out in the area we fenced for them. Two months later we saw round worms in their poop. I had thought that you usually only see adults if they have a very heavy infestation, or right after deworming (which we hadn't done since bringing them home). However, my husband had been feeding them lots of acorns which I thought I remembered reading can be antiparasitic and wondered if this was why they were coming out in the poo. I used pour on ivermectin with a dose I found online because they are now waaay to big and pushy for me to catch and give an injection to. We saw more round worms in the poop after that, and I tried to keep it picked up for a few days. I just dewormed them again yesterday (14 days later), and we are seeing adult roundworms again in the poo. I had thought that if the first deworming worked, then it would have killed all of the adults and we wouldn't be seeing them after the second deworming?? Right? Now I'm worried that I need to switch to something else?
Also, I'm terribly concerned about their pen. They are in about a 1/4 acre lot with a small "pond" which they poop in, so I can't possibly get all the poop out. Will they just continue to get reinfected? We plan on butchering sometime around February.
Also also, we were wanting to keep pigs in this area regularly in an effort to "seal" the pond. How long should we, or should we at all wait, before introducing new babies into this area after these pigs are gone? Will the water in the pond ever be free of round worms?
Sorry this is so long, and thank you for reading. I'm seriously stressed about his. Intestinal parasites are kind of a phobia of mine!

I deworm our pigs on a monthly basis. The first of the month, simply because it is easiest to remember. I use Wazine, which recommends adding it to their water, but I just put it in their feed because they will NEVER drink all the water in their tank.

I've never seen worms in their manure, other than the first set of pigs we ever got.

Ok, so good to know! For some reason most of the things I happened to read online suggested just doing it once when they came home and they would be good. I have wazine  from the chickens so I'll try that.... Thanks!

No, they will be shedding eggs along with the adult worms and by deworming on a schedule, it keeps them from carrying a heavy load.

OK, calm down and don't worry. We had our own "battle" with worms a while ago. We used wormers and still had worms. I am not for chemical wormers.
We use vinegar in the water and garlic in the feed and I have yet to find a worm in poop or at slaughter time, NONE. We provide a mineral block for the pigs. I think we use about a gallon of vinegar per 250 gallons of water. Don't feed them on the ground, use a trough or pan. That will help prevent intake of worms. Yes, they will still be rooting around, but it will help. If you have pigs that are more vulnerable to worms than others, eat them. That will improve your herd's resistance to them. Hope this helps.

We've had a few that seemed to stay wormy but most of our pigs don't have worms, and I clean the intestines for sausage casings, so I'd see them if they had them! I think some of it is just that some pigs are more prone to worms than others. I don't think the injections or pour-on are as effective as the dewormer in the feed. We use Safe-Guard. For pigs they say to break up the dose over 3 days, not sure why, but you can find the dose online to use if all you can find is for cattle or something. Ours won't eat it if it's gone rancid, and some of those packages seem to be old already when you buy them, but if you get a bad batch you can probably add molasses or something to get them to eat it - I've also seen people say they injected ivomectin into a Twinkie and fed that to the pigs.

We tried the ivomec in the treats. It did work, but the vinegar and garlic are easier and constant. We would sprinkle about 1/8 cup of garlic powder on their feed or mix it in. A little will make the whole load stink like garlic. I mean stink. WOW! I much prefer the vinegar. It works and they drink more water.

Just come upon this thread and have a question. Do you do both the vinegar and garlic at every feeding or just once a month? Thanks!
