*Mainly in dogs and pigs, sometimes ruminants
*'''In pigs''':
**Grossly:circumscribed reddened papules and plaques, thick crusting and scaling, fissures along ventral abdomen and medial thighs, sometimes generalised
**Microscopically: parakeratosis, acantosis, pseudoepitheliomatous hyperplasia, hypergranulosis
**Commonly secondary bacterial dermatitis
*'''In dogs''':
**Siberian huskies and Alaskan malamutes:
***Grossly: scales and crusts around mouthm chin, eyes, joints, prepuse, scrotum, vulva
***Microscopically: diffuse hyperkeratosis extending to follicles, superficial perivascular dermatitis with eosinophils
**Rapidly growing puppies:
***Grossly: scaly plaques on skin, nasal planum and foot pads
*'''In ruminants''':
**Grossly: alopecia, crusts and scales on face, neck and distal extremities and mucocutaneous junctions
**Microscopically: parakeratosis, sometimes hyperkeratosis

 ==Introduction==
 Zinc is an '''essential component of many enzyme systems''', including those related to protein and carbohydrate metabolism, and is essential for maintaining a '''healthy coat and skin'''.

-'''Pigs''' present with a disease called '''parakeratosis''' which appears as circumscribed reddened papules and plaques, thick crusting and scaling, fissures along ventral abdomen and medial thighs. Sometimes the condition is generalised and pigs may show mild lethargy, anorexia and depression. The skin lesions may resemble those caused by ''Staphylococcus hyicus'' however this usually occurs in younger piglets.

-In adult dogs such as the Husky and Malamute, zinc should also be supplemented and this may have to continue indefinitely to avoid relapses.
+In adult dogs such as the Husky and Malamute, zinc should also be supplemented and this may have to continue indefinitely to avoid relapses. Sometimes intravenous supplementation is necessary initially.
 '''In ruminants''', zinc supplementation can increase reproductive performance by increasing conception rate. There is also an improvement in hoof hardness and less white line disease.
