Proteins and vital amino acids
There are several dozen types of amino acids, which, placed end-to-end, form proteins. Some of these amino acids (hydroxyproline, serine, asparagine, glutamine, sarcosine, proline, glycine, etc.) may be created by the dog during digestion. However, 11 amino acids have to be found in the dog’s food ration, as he is unable to create them and would therefore become malnourished and ill : these are the vital amino acids (arginine, histidine, isoleucine, lysine, methionine, cystine, phenylalanine, tyrosine, threonine, tryptophan and valine).
These amino acids should not only be found in sufficient quantity in the food, but also in a set proportion in relation to each other, in order to improve their effectiveness. The nutritionists who manufacture super premium foods check this in the laboratory through an analysis of amino acid profiles (quantity and proportion).
To obtain ideal amino acid profiles, i.e. corresponding to the needs of the dog, it is essential to :
- on the one hand, create the best possible combination of animal and vegetable proteins (duck, chicken, turkey, egg, maize, soy, etc.)
- on the other hand, keep to the correct proportion of animal proteins (which should remain in the majority) and vegetable proteins.
