For everyone just getting started in raising any live stock, as we are. The one thing no one has ever mentioned to us or even written about in husbandry articles we have read. I have read over 200 articles and scientific papers on raising hogs and specifically on raising our Guinea Hogs, in none of these were the issues of diseases or parasites mentioned. Sadly, these two subjects didn't even enter my mind, until it happened and I started reading up specifically on diseases and other problems. The issue we currently have is Parasites, in our case it is Haematopinus suis commonly known as the Hog Louse or Pig Louse. We bought our breeding stock from closed herd operations, three different ones to ensure we had as much distance, genetically, as possible in this endangered species we decided to raise. None of the breeders we purchased from even mentioned that parasites could be a problem to watch out for. Once we found out we had an infestation, by doing our routine ear check/ belly rub, calls were made to our extremely helpful breeder hog providers and they all said "I've never had that problem", none of them could even give us a method of eradication other than using poisons. We do not want to put any stress on our livestock, we use no poisons on our land, so if we could find a way to address this issue without having to resort to poisons all the better. Calls went out to determine just how these lice could have suddenly appeared on our healthy hogs. Short of it is, these lice only live on hogs, the lice die if away from a host for two days and they don't have wings. This means, one of our hogs had them when we brought them home, or we inadvertently brought them home from the county fair we attended this year to meet other hog breeders and show animal people. The county fair doesn't allow infected animals on the grounds and every animal goes through an inspection and certification process before being shown, so it seems the lice wouldn't have come from there. More calls to our breed providers and none of them acknowledged that they might have had an infestation, so we are in the dark as to exactly where the bugs came from. We will be purchasing disposable coveralls and shoe covers for any more "visits" to other places to see animals. We will build a confinement pasture just for new arrivals, since we will be adding at least two more hogs to our breeding stock. No more trusting that a closed herd is insurance against big issues. What we do know now is how to treat the infestation with non-poison methods. In one day we have good results but we will continue to keep on top of this problem until it is absolutely gone. Vegetable oil works, Mineral Oil works, both will eradicate the nymph and adult stages, eggs are not effected by anything, not even the poisons so we will keep treating until all the eggs can either be removed from the hairs they are glued to or hatch and get wiped down with oil which does kill them by suffocation. Unfortunately the only way to insure no re-infestation is to spray down the whole pen area, all the trees, the hog house, the feed trough, the watering pool and pans, fence and posts, everything the hogs come in contact with. The spray is permethrin, unfortunately it has to be used since it is the only way to insure every possible nook and cranny is treated. Fortunately it is an organic and is relatively safe for the hogs and us along with our other animals. Lesson learned, if you are getting into any animal husbandry don't forget to learn about any and all problems that the critters could come up against especially diseases and parasites. We have treated our hogs; Adam, Eve and Lillbit twice now with the vegetable oil, the adult and nymph lice are gone but we will continue treatments for a month while I segregate them from the current pasture, treat it at least three times and then move them back. We are still in the process of building pasture paddocks and eventually we will have the ability to move them once a week for three months before they are back on the starting pasture area. We also inspect our hogs once a week, but now we will be doing daily checks so we find any issue before it can escalate to a real problem. I wanted to post up this experience for others just getting into livestock, I hope it saves someone else the Traumatic distress of discovering something wrong with their animals that was not expected or prepared for.
