Nee.
Ten eerste zouden we hier natuurlijk kunnen discussieren of een BARF dieet (met de goede verhoudingen) uberhaupt te eiwitrijk kan zijn. Naar mijn mening is dat niet het geval. Maar buiten dat, onderzoek wijst uit:

Environmental influences
The expression of hereditary diseases can be influenced by environmental factors. From the heritability estimates it can be concluded that factors other than genetics may play a significant role in the manifestation of elbow dysplasia. From a variety of studies it has become clear that nutrition has a major impact on skeletal development. Various field and standardized laboratory trials have demonstrated that food with high calcium content (Slater et al,1992; Kallfelz & Dzanis, 1989; Schoenmakers et al, 1999; Schoenmakers et al, 2000) can lead to disturbances in endochondral ossification. This makes the skeleton more vulnerable to mechanical influences in addition to osteochondrosis lesions and possibly chondromalacia. More recently, it has become clear that mild elevations in vitamin D intake will also disturb endochondral ossification by direct influence and not by increasing intestinal calcium absorption (Tryfonidou et al, 2002). High food intake and thereby excessive calcium and vitamin D intake can also lead to osteochondrosis (Hedhammar et al,1974; Lavelle, 1989). High calcium or high vitamin D intake causes cartilage retention in growth plates and thus disturbance of long bone growth, in particular development of the distal ulna and distal radius. Nutritional imbalances (like calcium of vitamin D excess) will not cause skeletal disturbances in dogs which are not genetically predisposed to develop these disturbances (Nap et al, 1993).
These findings are of great value for owners of a single dog, who want to prevent elbow dysplasia from developing in their pet. A high quality commercial dog food prepared particularly for puppies of large breeds should be provided, characterized by a lowered calcium content (~1.0% calcium of dry matter base) and a controlled vitamin D content (~500 IU/ kg food).
It has been shown that an increased level of high quality protein does not have a negative influence on skeletal development whereas it is of importance for soft tissue growth and immunological defence systems (Nap et al, 1993).
In summary, elbow dysplasias (including UAP, FCP, OCD and joint incongruence) can spread among certain dog breeds, due to the (over)use of a limited number of breeding dogs carrying a disease allele which is not necessarily expressed in all cases. Based on the published heritability estimates, environmental factors may play a role in the expression of clinical signs in genetically predisposed individuals. Since dietary intake of calcium and vitamin D may cause disturbances in endochondral ossification and thus may play a role in the occurrence of UAP, FCP, OCD and incongruence, unbalanced diets or excessive food (and thereby mineral) intake should be avoided. Although trauma may play a role in the occurrence of FCP the preventive or causative influence of physical activity on elbow joint development in dogs is still largely unknown. When the animal is not genetically at-risk, these environmental factors (e.g. diet and micro-trauma) will not play a significant role in the occurrence of elbow dysplasia. Screening of elbow joints to decrease the incidence of elbow dysplasia in the breeding stock and its offspring is advocated by many researchers and kennel clubs (Swenson et al, 1997, Kirberger et al, 1998).
En een goed BARF menu bevat ook niet teveel calcium en al zeker niet teveel vitamine D. Vitamine D gehalte is in een goed BARF menu eerder aan de lage dan aan de hoge kant. Dus als je geen vitamine D supplementen hebt gegeven: kan dat het probleem ook niet zijn.
Geen idee wat je exact hebt gevoerd, maar een goed BARF menu veroorzaakt geen ED. Ook niet als je pup uit brok-lijnen komt. En 50% vleesbot is niet heel laag natuurlijk maar als ze goed bevleest zijn geweest ook zeker niet te hoog. Ian B. voert zijn pups gerust 60% tot 70% vleesbot. Al zeker 35 jaar.
