I am laughing my head off at 'hell hounds'... they couldn't even come close, they are the soppiest, loveliest Golden Retrievers...
D0oin, I don't have his direct number asctually, but he's always after mine... 
Flatbread, on an entirely more srious note... I'm not sure where you got the idea from to supplement your puppies diet at all, especially with goats milk and egg yolks, but it's actually quite an old fashioned idea and one that will not provide optimum nutrition for your puppies. A bitch's milk is absolutely the best thing for her puppies in terms of nutrition and for their immune system, in fact, immunity recieved from the bitch can be vital for your puppies. If the bitch is healthy and well then there is no need to supplement the puppies with anything and as her milk works entirely on a supply and demand basis then anything you give her in addition to this not only is a substandard replacement for her milk but will reduce her supply overall. If you felt the need to supplement (and there is no need) then there are specially designed puppy 'forumla' milks which are better than the goats milk and egg yolk, but nowhere near as good as the bitch's own milk.
Regarding the stats re: insurance and everything else re: pedigrees being less healthy than mutts... when you consider than over 90% of KC registrations are from puppy farmers, where a high incidence of inbreeding and breeding with no care for anything at all except making puppies to sell occurs, then on top of that the number of litters registered by BYB's, then the number of 'pedigrees' that aren't registered or registerable due to poor breeding practices that leaves only a very small number of responsibly bred pedigree dogs (in the scheme of things!). So I don't think we can place too much importance on such studies when responsibly and well bred pedigrees are worlds apart from those that are not.
Of course, if you have a study that only takes into account responsibly bred pedigrees and mutts and compares them healthwise, I'd be interested to see it...
