Thanks! That's what I was thinking it stood for, oddly, even though I

hadn't seen it. That's so weird that that thought was actually

verified. Ok, hopefully this link has a conversion factor...

Argh! No conversion factor! But thanks to your verification of the

meaning, I was able to dig up a few other things, but still with no

luck for a conversion factor. The best thing I've got is this rather

vague statement:

" Vitamin D 1 I.U. = 1 USP unit= the vitamin D activity of 0.025

micrograms of crystalline vitamin D3. Products assayed against this

new standard (official May 1, 1951) will have only 93.4 per cent of

the unit dosage? shown when assayed against the last USP Cod Liver Oil

Reference Standard. An even greater difference is shown when the new

USP Standard is used for assay of chicken feeds. Products assayed

against the new standard show about 75 per cent of the unitage shown

when assayed against the last USP Cod Liver Oil Reference Standard. In

order to differentiate between the present A.O.A.C. Chick Unit, and

the new Unit which is 33 per cent larger, the term " International

Chick Unit " has been adopted. "

http://www.mail-archive.com/sciencelists (DOT) csi.cps.k12.il.us/msg00055.html

....and the Kansas Dept. of Agriculture has this enormous list of

regulations that has at least one reference to it, that told me

nothing, and might define it elsewhere but the document is too

enormous to look for it. A search for " international chick unit " with

quotes Googles up only a few results in English.

It seems like it is equal to an IU of D3, and not relevant to D2.

That's my impression. But I can't find anything to clearly say that.

Thanks Lana. What I need to find, though, is a conversion factor

between ICU and IU. I was hoping that 1 IU D3 = 1 ICU D3 but

apparently that's not the case. It's hard to tell though. What on

earth is " mu.g " ??? Is this suppposed to be some whacked out

abbreviation for micrograms? Usually " mcg " is used if the Greek

letter that is absolutely not pronounced like " moo " is not an

available character. This is a little confusing.

Well, the way I read the aside in the parenthesis is one thousand IU =

1 MIU = 1 ICU.

mu.g is mili units per gram.

Lana,

Are you sure? The universal symbol for " per " is " / " . A period is not

a valid symbol for " per. " Also it wouldn't make much sense for a unit

to be given in terms of per gram per kilogram. Also, one MIU is said

to be equal to 1000 ICU, not 1 ICU:

> " The control group ( " control " ) was provided with a feed supplement of

> CC at a concentration of 55 .mu.g/kg feed (2.2 MIU/ton; where " MIU " is

But what is unclear is if " international units, " as equated with

" international chick units " is the same international units that

applies to non-poultry units. If they gave a clear mass equivalency I

would be able to convert it into the convetional IU easily. What is

confusing is the term " mu.g " which appears to be a mass unit, but

isn't one I've ever seen before. And I don't think it is possible for

it to mean milliunits per gram, for the reasons stated above.

Thanks for your help and anymore that can be offered.
