Mostly Indiana, but also was in a few other states briefly. Flew over
New York.... Cripes the size of it!!!!

I couldn't believe the coincidence; there weren't many British people on
the aeroplane & I doubt whether any of the others had anything to do
with chickens. She's Dr Lucy Tucker of Alltech senior poultry manager
for Europe.

I probably didn't do a fair representation of what she said. I never was
much good at writing.... just maths. I think that she did say something
about it being a more readily available source of carbohydrates, quick
ready energy? Thus being more heating & possibly causing irritability,
but she definitely said that it was never hot enough in Britain for this
to be a problem & that there is no real reason why corn should cause a
heating problem in summer months here.
She talked quite a bit about various forms of protein, (especially soya)
& its' availability to chickens (& humans). Apparently we're a bit tied
because of legal aspects. To be quite honest a fair bit about proteins
went over my head to some extent. I think that she said that other
things (enzymes?) are added to make soya a better & more readily
available for chickens. Fishmeal & meat by-products, as I expect
everyone knows, are much more suitable readily available forms of
protein for chickens & humans. She also spoke of how soya was being used
as a cheap ingredient in so many products that she could see allergies
being likely to occur with increasing frequency. That one should never
eat organic cereals because they are not allowed to use fungicides.
Therefore there is an increased risk of mycotoxin build up in the liver.
Apparently this works in a similar way to ragwort toxin build up in the
liver & cannot be cleared?? (Remember I don't know if any of this makes
sense, I'm just repeating my interpretation of what she said.) She said
that the government(???) was keeping a lid on this info but she could
see the lid being blown off it (again???) & a big fuss being made about
mycotoxins within the next (X number) years.

I do remember that she said that the symptoms of selenium overdose in
horses were the same as selenium deficiency. I'll write a bit later &
ask again about the form of selenium which is not good to use. She
spends most of her time travelling the world going to universities &
conferences; which she said becomes rather boring after a few years.
Flying for long distances is really not fun as I found out.

Diagnosed & thus saved a flock from Mycoplasma gallisepticum (acute
form) I'd never seen the acute form before. Recognised Mycoplasma, but
with accelerated progress, managed to get some tylosin used that in
conjunction with oxytet injections for the worst cases. Confused by
rapid progress spoke to a vet who informed me that there are both
chronic & acute forms in US. Disinfected myself on return, I don't want
it in my birds. Another friend (Rourke Hiland) had runners, exhibition
type, .... prefer ours. Rourke also had ancona ducks. Do you know who
created these & where? They have magpie pattern I think that the main
difference is in the beak.
