Transfer Factor from any animal except cow - cross post

[Guest guest]

Has anyone heard of or used transfer factors from any other animal

working for entrenched viral illness esp in ASD kids (eg., pig,

chicken, sheep, etc)? We are trying to scrupulously avoid cow

products to eliminate BSE (mad cow) risk, and surely there are other

forms of transfer factor that are effective. Does anyone know where

to get them? There is the whole country of India with over a billion

people, most of whom are loathe to consume any cow products; perhaps

some Indian doctors know of alternatives of transfer factor used there.
