1. Growing pigs develop rough thickened skin with a dull coat and poor growth rates.
2. Lesions are most obvious over the abdomen, legs, and behind the ears.
3. The skin is dry and crusty rather than greasy.
4. The ration history suggests mineral imbalance affecting zinc availability.
5. No mites are found on skin examination.

Diagnosis

Swine Parakeratosis

This case is most consistent with Swine Parakeratosis because the pigs have dry hyperkeratotic skin disease with a ration history suggesting zinc deficiency. The most important clues are the crusting pattern and absence of mites, which make mange less likely.
