They get mazuri feed. I've been mixing youth and adult feed to help them keep on weight due to the super cold weather. They also get some mixed veggies, chicken, eggs, and sometimes apples. Alright I'll get some treatment for him. Should I treat the other two young ones as well? The have it missing around their eyes and that's it. It's weird because both of the adults hair is fine. Not missing any hair.
I don't know about pigs but I had mites come in on Straw and infest my rabbits and since rabbits would eat it and it was nutritionally void I just quit using straw all together and switched to locally sourced hay with zero problems since. I believe I have heard of suspicions that goats have contracted mites from straw as well from several people.
From what i can see in the pics i think they are perfectly fine. The first winter on young pigs can very often cause excessive dry skin and make them itchy so they rub their hair off in places. If you can rub anything that looks flaky off of them fairly easily it is not mange.
I doubt mites would come in on straw. Mites that affect pigs can only live for 5 days away from a host. Also if the adults dont look like they are rubbing their hair off and have mange you can be pretty darn sure it is not mange because mange is very contagious and only has an incubation time of approx 15 days. Mange signs are head shaking A LOT and rubbing on sides of pen(to the point of bleeding/creating scabs). After approx 2 months being infected they will develop red pimples all over their skin and become even more itchy after that comes the crusty patches.
Also ivermectin treats mange so if you have wormed them with ivermectin lately it isnt mange.
I use straw for warmth since it holds heat better, and hay for extra grain since grass is lacking. They're not itching at all when out so maybe it is just dry skin.
Mange or mites in small numbers of backyard pigs that do not come from auctions or other large scale breeding farms generally will never see a case of mites or mange, it just isnt really common because as i mentioned it can only be spread from pig to pig or within 5 days after the original host pig leaves.
Okay yeah, we got our oldest 2 from an individual as babies and haven't brought in any new ones. And spot doesn't try to rub against me when I run his patchy areas
