hallo brini,
wie ist dann jetzt deine entscheidung bezüglich orijen ausgefallen? als zweitfutter oder nur als leckerli?
kann dir nur empfehlen mal in ein forum unserer amerikanischen kollegen hineinzuschauen. dort wird orijen über alles gelobt. und der amerikanische markt ist sicher größer als der bei uns.

u.v.m.
eine interessante email von einem anerkannten tierarzt der studien vorlegt, die das gerücht, hohes protein schade dem hund, widerlegen:
zu sehen auch im letzten link:
I want to leave you with an email that was sent to us by Dr. Steve Marsden. He assisted us in formulating this food. He is very well known and respected in his industry(he is a homeopathic vet and nutritionist). Below he addresses some typical concerns regarding high protein diets-including large breed puppies and accelerated growth.
"
* higher protein diets are believed to accelerate bone growth
o Nap RC, Hazewinkel HA, Voorhout G, Van den Brom WE, Goedegebuure SA, Van 'T Klooster AT reported on this issue in J Nutr. 1991 Nov;121(11 Suppl):S107-13. The study was entitled Growth and skeletal development in Great Dane pups fed different levels of protein intake. The authors found that while relationships exist among growth rate, calcium/phosphorus ratios and overall energy content of the diet, dietary proteins have no discernible accelerating effect. The maximum protein level tested was essentially the same as the protein level in Orijen.
* higher protein diets cause kidney problems
o Many studies have demonstrated that protein restriction is often helpful in managing chronic renal failure in dogs, but there are no studies to suggest higher protein diets can cause renal failure. Some studies have demonstrated rises in blood urea nitrogen following use of higher protein diets, but none show significant increases in creatinine. Between the two, urea and creatinine, only creatinine is a specific indicator of renal failure. Urea levels vary widely for a number of reasons, including the level of protein in the diet, anorexia, the effect of various drugs, and of course impaired renal blood flow. Rises in urea in the absence of rises in creatinine and normal urine concentration do not indicate renal failure.
o Following is a reference specifically confirming that high protein diets do not cause renal failure:
o Bovee KC; High dietary protein intake does not cause progressive renal failure in dogs after 75% nephrectomy or aging; Semin Vet Med Surg (Small Anim). 1992 Aug;7(3):227-36.
* Lastly, it is commonly held that high protein diets predispose to calcium loss from bone, since low protein diets are often used to manage calcium oxalate stones in the bladder, and since high protein diets are an oft-touted (though unproven?) risk factor for osteoporosis in people. Interestingly, a recent study shows the exact opposite, that higher protein and even high calcium diets in dogs promote lower incidence of calcium oxalate stones. That study's citation is as follows:
o Lekcharoensuk C, Osborne CA, Lulich JP, Pusoonthornthum R, Kirk CA, Ulrich LK, Koehler LA, Carpenter KA, Swanson LL. Associations between dry dietary factors and canine calcium oxalate uroliths. Am J Vet Res. 2002 Mar;63(3):330-7
Clinically, I would have to say that all our experiences with this kind of diet are in agreement with these studies. Much of the perception that higher protein diets are harmful has been promulgated by the veterinary profession based on old and incomplete information. It is entrenched in owner's minds because of the credible source. Until the most recent research on the subject becomes mainstream in the veterinary profession, you are constantly going to be encountering this kind of bias. At least now, though, you can cite some studies to back up your beliefs."
