"in cats, the protein from plants was more highly digested than animal protein." THAN FOR DOGS !!!
All studies were conducted over a period of 110 months. The canine studies used 226 healthy dogs and the feline studies used 296 healthy short hair domestic cats
There were 459 canine studies and 427 feline studies.
Funding This research was funded by Hill’s Pet Nutrition Inc.
Conflicts of Interest The authors are or have been employees of Hill’s Pet Nutrition, which manufactures and sells pet foods to optimize the protein nutrition of healthy pets and to aid in the management of disease.
SIMPLE SUMMARY
Because dogs are omnivores and cats are obligate carnivores, it is of value to pet owners and nutritionists to know how well they digest protein from plants and animals. This study evaluated the difference in digestibility using plant and animal protein sources, which are used in the pet food industry. These plant and animal sources resulted in protein digestibility that met or exceeded that expected for dogs and cats. As previously shown, cats had superior protein digestibility as compared to dogs. Regarding the difference in digestibility between the proteins from plants or animals—as a class, there was no difference between plant and animal protein in dogs. However, in cats, the protein from plants was more highly digested than animal protein.
CONCLUSIONS
When prepared in the distribution chain of these ingredients, and manufactured through the extrusion parameters of these foods, plant proteins are similar to animal proteins in protein digestibility. Cats had an increased protein digestibility in response to increasing plant protein, while protein digestibility was not influenced in dogs. As plant protein inclusion was not associated with reduced protein digestibility, it provides a satisfactory source for the complementation of animal protein ingredients in meeting the amino acid needs of pets.
ABSTRACT
This retrospective study used 226 dogs and 296 cats to evaluate whether protein absorption was influenced by species, and within species, what influence increasing the percentage of total dietary protein, as plant protein, had on protein absorption. Each food was evaluated by at least one study with a minimum of six dogs or cats assigned to each study. Dietary inclusion of animal and plant based protein was calculated by analysis of ingredients and dietary inclusion level. Both dogs and cats were able to digest dietary plant protein, with protein digestibility in dogs unchanged as plant protein increased, while in cats, eating dry food, an increase in plant protein, was associated with increased protein digestibility. When individual plant high-concentration protein sources (excluding the protein from whole grains) were evaluated (i.e., soybean meal, soybean protein isolate, corn gluten meal, and rice protein concentrate) there was no response to increasing protein from these sources in the dog. In the cat, there was a significant positive effect on protein digestibility associated with an increasing concentration of corn gluten meal. In summary, as the dietary protein shifted from striated muscle and other animal proteins to plant based proteins, there was no effect in the dog, while in cats, increasing dietary plant protein was associated with increasing protein digestibility (5.5% increase at 50% protein from plants in dry cat food). Protein digestibility of food in dogs and cats is similar, if not enhanced, when the plant protein sources are concentrated from soybeans (soybean isolate, soybean meal), corn (corn gluten meal), or rice (rice protein concentrate).

Je met ici une google traduction du résumé, et de la conclusion : Résumé simple Parce que les chiens sont omnivores et les chats sont des carnivores obligatoires, il est important pour les propriétaires d'animaux et les nutritionnistes de savoir à quel point ils digèrent les protéines des plantes et des animaux. Cette étude a évalué la différence de digestibilité en utilisant des sources de protéines végétales et animales, qui sont utilisées dans l'industrie des aliments pour animaux de compagnie. Ces sources végétales et animales ont entraîné une digestibilité des protéines qui a atteint ou dépassé celle attendue pour les chiens et les chats. Comme indiqué précédemment, les chats avaient une digestibilité des protéines supérieure à celle des chiens. En ce qui concerne la différence de digestibilité entre les protéines végétales ou animales - en tant que classe, il n'y avait pas de différence entre les protéines végétales et animales chez les chiens. Cependant, chez les chats, la protéine des plantes était plus digérée que la protéine animale. Conclusions Lorsqu'elles sont préparées dans la chaîne de distribution de ces ingrédients et fabriquées à partir des paramètres d'extrusion de ces aliments, les protéines végétales sont similaires aux protéines animales en termes de digestibilité des protéines. Les chats avaient une digestibilité accrue des protéines en réponse à l'augmentation des protéines végétales, tandis que la digestibilité des protéines n'était pas influencée chez les chiens. Étant donné que l'inclusion de protéines végétales n'était pas associée à une digestibilité réduite des protéines, elle fournit une source satisfaisante pour la complémentation d'ingrédients de protéines animales pour répondre aux besoins en acides aminés des animaux de compagnie.

Interestingly, it is the cat that showed a positive digestibility response to increasing dietary corn gluten meal while digestibility in the dog was unaffected. The cat has an increased ability to digest protein in general, which may influence its capacity to digest corn gluten meal as compared to the dog.
