One of the important reasons for variety in protein sources is to vary the amino acid that's in the smallest quantity (which affects protein use), using differing sources with differing weak points.

We got very far afield, but if anyone wants book recommendations (in addition to the one I gave above) about how amino acid content in animal flesh varies by what they are fed, what group of muscles are under discussion -- even (to a lesser extent) the soil makeup of pasture-fed poultry, etc., just PM me.

Connie -- any material on the internet does not qualify to be considered as a peer review. Two references were to book critic by Chris Masterjohn. I was familiar with Masterjohn’s criticism. Chris has no biochemical education and he is associated with Weston Price -- in the business of selling supplements. His review seems scientific but in fact it is full of inaccuracies and misunderstandings of the statistics involved (this review was rebuked by Dr. Campbell and others in various medical journals). The second review is subjective and contains no scientifically grounded and no scientific references to the opinion expressed.
You were criticizing me for bringing The China Study in relation to dog diet, but you referenced material that referenced human diet and not canine diet. Again, my reference to the China Study was only in relation to Dr. Campbell's assessment that Casein represents all animal protein from practice diet perspective.
Here is my bottom line. There is no evidence that so called protein diversity has any benefit for canine diet.
From a common sense perspective, canines in nature living in different geographical areas would be exposed to different sources of protein (some feed on deer, some on Caribou, some on rabbits, etc.) As far as I know, canines in nature do not eat salmon (neither wild or farm raised ). I believe that it is important to feed some organ meat for its nutrient content and a variety of fruits and vegetables ground and mixed with meat (avoiding raising, garlic, wheat, and onions). I avoid feeding too much of very fatty foods.
In my opinion, Connie's original advice to diversify meats for their different protein profiles has no basis from scientific and common sense perspectives. At the same time, I do not see any harm to feeding different meats. I this it is more important to feed the most natural meat source one can get -- clean of hormones, antibiotics, and from animals that were raised on most natural diet.
I don’t see any point to continuing this discussion – we seem to agree on main points anyway.

Every criticism I have seen of the one book you mention repeatedly, including those by people generally lauding the book, includes that basic flaw of equating casein with all animal protein and with lumping all animal protein into one bucket, as it were.

If you would read any book (any other book) about amino acids, such as the 2nd edition of Amino Acids in Animal Nutrition, it would be be immediately clear that the structure of animal protein is not Dr. Campbell's forte, despite his interesting theories and assertions (many of which ARE backed up by research and citations).

QUOTE: Amino Acids in Animal Nutrition
..... since the publication of the first edition, as Amino Acids in Farm Animal Nutrition, there is now a need to take into account advances in the amino acid nutrition of a wider range of animals, including companion animals. In this new edition, the editor has attempted to retain chapters imparting strength to the first version, while introducing authors with new ideas and vision, as well as chapters on other animals such as cats and dogs.END QUOTE from Amino Acids in Animal Nutrition

Using one book makes your information limited. You are obviously literate and intelligent. I'm not sure why you insist on particularly defending the biggest area of "opinion presented as fact" in that one book. Even the simple chart that I provided of amino acid contents of various foods makes it glaringly clear that Campbell misspoke when he lumped casein and all animal-source proteins as interchangeable.

When you say "There is no evidence that so called protein diversity has any benefit for canine diet," I believe that you may be relying 100% on that single book and that you are completely ignoring (for one thing) big ag's manipulation (whether deliberate or not) of amino acid profiles using feed (and other methods).

You are correct. We are arguing the unarguable. The info just is not in that book, and that is the one book you prefer to use.

However, you forced me to drag out some of my course work and textbooks, and that's always a good thing for someone of my "mature" years.

To the reader: I (and Leerburg) urge that you follow Cindy's well-researched Leerburg diet recommendations:

This is obviously in disagreement with "There is no evidence that so called protein diversity has any benefit ....." But even if you fall in with the idea that different proteins are not diverse in amino acid profiles, don't forget vitamins, minerals, and EFAs.

And I we return now to the thread's topic.

Does anyone have a reliable source of shipped canned green tripe?

Connie, I don’t know if the quality is as good (doubt it&hellip but PetCo sells green tripe in a can .

Made by Solid Gold...

Oh, good!

I can't reliably get "fresh" green tripe. (It's hard to describe it with such a nice-smelling word.)

Connie,

Hambone eats the canned tripe from Solid Gold and loves it!!! No itching, swelling, rashes, etc from it. I know that is a subjective recommendation, but Hambone wants you to know, it smells kinda garlicky and not so bad...
but mom still won't try it.

I've ordered Tripett from West coast Supply (Formerly ePet Pals) and got good service. The Solid Gold stuff has potato added. Maybe something else too, I don't remember.

OOOO I like that even better Steve!

Thanks.
