Hmm!! Very interesting.
Hmm!! From what I gather, most of the birds they test and deal with are from farms larger than the average backyard keeper. If so, those poults were almost certainly fed a commercial feed. Even if they were from a small keeper, many of us feed commercial feeds. Not to always be suspicious of commercial feed, because goodness knows many of us depend on it, but I always wonder at quality vs. quantity. Cheaper ingredients (specifically fats) are less stable over the period of a month or three, and make fat soluble vitamin deficiencies much more likely.
Just got this in an email from UC Davis:
In it is this:
Poultry and Other Avian
Nutrional encephalomalacia due to Vitamin E deficiency was diagnosed in 3‐week‐old turkey poults with increase in mortality (1.5% per day) in a flock of 10,000 birds. The birds were ataxic, lying in lateral recumbency and paddling. Necropsy revealed severe petechial hemorrhages on the cerebellum associated with microscopic multifocal necrosis and thrombosis. Vitamin E levels
in the liver ranged between 0.53 and 2.2 ppm (normal range: 3‐15 or greater).
