Since not all people with genetic predisposition for lupus contract the condition, it is important to evaluate what environmental factors are indicated in disease prevention. While a few genes have been studied as factors for lupus, more may be involved that have not been identified.ince not all people with genetic predisposition for lupus contract the condition, it is important to evaluate what environmental factors are indicated in disease prevention.

Ducks and turkeys with a niacin deficiency show a severe bowing of the legs and an enlargement of the hock joint. The main difference between the leg seen in niacin deficiency and perosis as seen in manganese and choline deficiency is that with niacin deficiency the Achilles tendon seldom slips from its condyles.n the niacin-deficient hen, weight loss, reduced egg production, and a marked decrease in hatchability can result. Turkeys, ducks, pheasants, and goslings are much more severely affected by niacin deficiency than are chickens.
Somebody PM'ed me recently with a question about a lame gosling so I thought this would be a good reminder for all of us. I was reading in Dave Holderread's duck book regarding what he recommends for the all too common niacin deficiency seen in ducklings.Niacin is a B-vitamin lacking in chick starters. Lack of it can cause leg problems in ducklings and goslings.reatment: Ducklings exhibiting niacin deficiencies and be CURED by giving them 100-150 mg. niacin (crush tablet) per gallon until they are 8 - 10 weeks old. If not treated they can have permanently stunted growth and/or crippled.
