Biotin Deficiency Dermatitis in Geese

Biotin deficiency dermatitis is a skin disorder caused by too little available biotin, also called vitamin B7, in the diet. In birds, biotin helps support normal skin and keratin formation. When geese do not get enough usable biotin, the skin can become dry, rough, inflamed, and prone to cracking. In poultry, the most typical lesions develop on the feet and on the skin around the beak and eyes.

Although most published veterinary references describe this problem broadly in poultry rather than geese alone, the same nutritional principles apply to waterfowl. Geese raised on an incomplete ration, spoiled feed, or a diet not formulated for growing waterfowl can develop deficiency signs. Young birds are usually more vulnerable because they are growing quickly and have less room for nutritional mistakes.

This condition is often manageable, especially when caught early. Still, skin disease in geese is not always caused by vitamins. Footpad injury, wet bedding, bacterial infection, parasites, and other nutrient deficiencies can look similar, so it is wise to involve your vet if lesions are spreading, painful, or affecting walking.

The most common cause is an imbalanced diet. Geese need a complete ration that provides vitamins in the right amounts and in a form the body can use. Problems can happen when birds are fed homemade diets without proper formulation, old or poorly stored feed, or feed intended for another species or life stage. Growing goslings are especially sensitive because their nutrient needs are higher.

Biotin deficiency can also be linked to feed quality, not only feed label claims. Veterinary references note that some biotin in feed ingredients may be poorly available to birds, and rancid fats can further damage vitamin stability. That means a ration can look adequate on paper but still fail in practice if the feed is stale, oxidized, or improperly stored.

Another important point is that skin lesions are not unique to biotin deficiency. Pantothenic acid deficiency can cause similar facial and foot dermatitis in poultry. Wet bedding, abrasive surfaces, frost injury, parasites, and bacterial pododermatitis can also create crusting and sores. Your vet will look at the whole picture before deciding whether biotin deficiency is the main issue.

Diagnosis usually starts with history and pattern recognition. Your vet will ask what your geese are eating, how long the problem has been present, whether the feed was recently changed, and whether other birds are affected. A physical exam helps map where the lesions are located and whether there is pain, swelling, discharge, or signs of infection.

In poultry medicine, nutritional deficiencies are often diagnosed from the combination of diet history, clinical signs, and response to correcting the ration. Feed review is very important. Your vet may recommend checking the feed tag, replacing the ration with a fresh complete waterfowl or all-flock feed, and evaluating storage conditions. If available and practical, feed analysis can help confirm whether the ration is deficient or degraded.

Testing is sometimes limited because blood biotin levels are not considered very sensitive indicators in birds. Veterinary references note that liver or kidney biotin levels are more useful, but these tests are not routine for backyard geese. Your vet may also rule out look-alike problems such as pantothenic acid deficiency, bumblefoot, mites, fungal or bacterial skin disease, and environmental foot damage.

Prevention starts with a complete, species-appropriate diet. Geese should be fed a balanced ration that matches their life stage, especially during rapid growth. If you use an all-flock feed, confirm with your vet or feed manufacturer that it is appropriate for geese and that birds are not relying too heavily on treats, scratch grains, or pasture alone.

Feed handling matters too. Buy fresh feed in amounts you can use promptly, store it in a cool and dry place, and discard feed that smells stale, oily, or moldy. Vitamins can degrade over time, and poor-quality fats can make nutrient problems more likely.

Good housing supports healthy skin. Keep bedding dry, reduce mud and manure buildup, and provide footing that does not constantly abrade the feet. If one goose develops suspicious skin lesions, review the whole flock's diet right away. Early correction is usually much easier than treating advanced foot sores later.
