| + | Also Known As: '''''Yellow Fat Disease''''' |
| | | |
− | *Yellow fat disease
| + | ==Introduction== |
− | *Many species except ruminants
| + | '''Steatitis''' is also known as ''''yellow fat disease''''. It occurs in many species including cats, reptiles and mink. It is not seen in ruminants. |
− | *Cause by diet high in polyunsaturated fat and low in tocopherols
| |
− | *Inflammatory response of adipose tissue to oxidative damage
| |
− | *Vitamin E responsive
| |
| | | |
| + | The condition occurs in animals fed on a '''fat-laden diet''',''' high in polyunsaturated fat and low in tocopherols'''. This causes an '''[[Inflammation|inflammatory response]]''' of '''adipose tissue''' due to '''oxidative damage'''. [[Vitamin E Deficiency|Vitamin E deficiency]] is thought to contribute to the condition. |
| + | |
| + | ==Clinical Signs== |
| + | The animal normally presents with '''firm nodules in subcutaneous tissue''' that are '''yellow or orange in colour'''. Mink may also present with abnormal locomotion and sudden death. |
| + | |
| + | ==Treatment & Prevention== |
| + | The condition is '''vitamin E responsive''', therefore affected animals should be treated with oral or injectable vitamin E supplementation and fed on a '''low fat diet'''. |
| + | |
| + | The condition is prevented by feeding an '''appropriate diet''' (low in polyunsaturated fat) and supplementing the diet with '''vitamin E'''. |
| + | |
| + | ==Prognosis== |
| + | If the condition is recognised when the signs are mild, then prognosis is good - with complete reversal of signs. More chronic lesions are harder to treat as they may be walled off by a dense capsule of fibrocollagenous [[Connective Tissue Histology resource|connective tissue]]. |
