Label analysis

Nutritional profile of the food

The calculated energy density of Royal Canin Giant Adult kibble is approximately 390 Kcal per 100g.
25.1% of total energy is provided by protein
31 .3% of total energy is provided by assimilable carbohydrates 43.6% of total energy is provided by lipids or fats

Quantitative protein analysis

The calculated protein-calorie ratio of Royal Canin Giant Adult is 72g of protein for 1000Kcal. Royal Canin Giant Adult kibbles are sufficiently "concentrated" in protein to cover the protein needs of a whole and active large dog. On the other hand, their protein-calorie ratio is insufficient for the needs of a not very active and/or sterilized giant breed dog.

Qualitative protein analysis

The phosphorus content of these kibbles is 0.70% and the calculated protein-phosphorus ratio is 40.

" The most"

The ingredient used in the greatest quantity in these croquettes before cooking is dehydrated poultry protein. We know this because it is this ingredient that appears first in the list of ingredients. As these proteins are already dehydrated, water loss during the cooking process of the kibbles is minimal.There is therefore a good chance that this ingredient will also be the one that is present in the greatest quantity in the finished product.

" Least"

These croquettes seem to be quite rich in proteins of vegetable origin which are of lower nutritional quality for the dog. The clues that tell us this are the low phosphorus level as well as the mention of 6 ingredients that are sources of vegetable protein in the list of ingredients. The origin of animal proteins remains rather vague and their percentage is not indicated in the list of ingredients.

In these croquettes, lipids are mainly provided by animal fats, fish oil, soybean oil and borage oil.
The omega 6 content is 3 .93% and the omega 3 content is 0.95% including 0.4% EPA and DHA. The omega 6/3 ratio is 4.1.

" The most"

These kibbles are sources of long-chain omega-3 fatty acids and have a good omega-6/omega-3 ratio.

Available carbohydrates

In these kibbles, the main sources of available carbohydrates are corn, corn flour, wheat and rice. The estimated percentage of available carbohydrates of these kibbles is approximately 35%.

Absorbable carbohydrates are carbohydrates that provide energy in the form of calories to the dog. Their percentage is calculated according to the following formula: %assimilable carbohydrates=100-%proteins-%lipids-%cellulose-%ash-%moisture. When not specified by the manufacturer, humidity is estimated at 10%.

" Least"

These croquettes seem a little too rich in assimilable carbohydrates. This can cause some digestive issues for dogs that have trouble digesting starch. Rice, which is the most digestible source of assimilable carbohydrates for the dog, is the one that comes last in the list of ingredients. It is therefore the one that is used in the smallest quantities in these croquettes. In addition, the presence of 35% of assimilable carbohydrates is in line with the observations made above, namely that the proteins in these kibbles are mainly of vegetable origin.

Calcium and phosphorus

The calcium percentage of these kibbles is 1% (i.e. a calcium "concentration" of 2.6 g per 1000Kcal) and their phosphorus percentage is 0.7%, i.e. a calcium / phosphorus ratio of 1.4.

" The most"

These kibbles follow FEDIAF recommendations in terms of calcium and phosphorus content.
