My vet suggested we keep a good broad spectrum anti-biotic (LA200) or something like that on hand, just to save him a trip and me the expense. Also we keep wormer (Ivermectin) , pre-breeding and pre-farrowing vaccinations around. For the piglets we keep iron and some immunizations as preventative, a quick read thermometer, syringes and needles. Our vet is great, he has talked us through a lot, he eats pork too. When it comes to steroids, hormones and the such when needed, he has to come out or we take him the hog (easier said then done). Farrowed once and the sow got a serious infection from a mummy, (109 degree fever) went from great to almost dead in a few hours, thank God for our vet... had her on her feet and nursing in about 6 hours. Almost lost a 40lb due to severe sunburn, resulting in dipody pig syndrome, then worked into paralysis, the vet saver her as well, turned out to be one of the best we raised.... I always seek his advice before administering any meds. Just be very observant, spend time with the hogs, watch and listen, and be specific with the vet... the more info they have the better for everyone. Find a good vet that will work with you, not all of them are in it for the money... We are not vets, but a good vet can talk you through a lot.
