ASF growing up with thin to no fur?

I am surprised that some think red, irritated, balding skin is normal.

Its not normal, and is correctable.

that my thing though the skin not red it almost matches the pattern when the hair does come in later ...

well i got the hogg feed at southern states ( looks like rabbit pellets) and we'll see how ( if ) they inprove.

First of I want to state that I raise regular mice not ASF's but with that said I have experienced the same thing. Some of my mice seem to loose their hair or become bald or have little wispy hair. Some of them stay this way to adult some grow out of it and get normal hair again. Their skin is fine is has no sores or redness, just no hair. I DO feed Mazuri feed, have water available at all times, and change bedding often, I use pine shavings from Kotter and Smith (the best deal I can fine 9 cubic feet compressed for $5).

I have no idea what causes it but I dont think it is food, at least not for me. I buy 2-3 50# bags at a time from my feed store, I have a standing order in so it is fresh, hasnt been sitting around for months at a time.

Mice also have a recessive hairless and fuzzy genes. The ASF's with whispy hair does not seem to be related to a hairless or fuzzy gene.

mostly to update and get ideal whatot try next.

I had the asf on the goat/hog feed for almost amonth now andther beenno real change in the tin haird guys ( outside they now have a pink/red skin tone) they are eating the feed and anytihng else I happen to offer them. I am gonig ot try something else the next time I am gett supplies for them. I found them a great snack chew toy by acc. My niece gave them a dog chew bone ( milk bone ) and they go nuts on it i never seen a large scale tug of war over one .. I am consdiering it possible a reactin otthe brand/typ of pine i been getting since it from southern stata and not as dry feeling as the what ihad before.
