I have been using hog feed maybe same amount now as well, I feed blue seal pig and sow grower i beleive it is and doggie bag dog food-as was said the hog feed lowere in fat. Pretty much all of mine have been doing great. I did lose a couple s but the rest have been fine so may be unrelated. My litter numbers still about same. I did lose 3 pregnant hairless though and was a bit concerned about that but not sure if pregnancy related or food relate-it was there first litters and I obtained them as s so didnt know there history. They definitely go through the hog feed quick though. I just couldnt afford to feed mazuri anymore-can get 100# of food now less than 50# of mazuri was
