The diet protocol for the dogs determines the inclusion of a quantity of grain, rich in starch, so that the extrusion machines cause an appropriate expansion of the product.
In general, dogs do not have access to a wide range of food and for them are often given few choices, that is, only the food available in the trade that is rich in flavoring making them consume more than they really need.
The owner thinks that there is nothing negative in this, but problems of nutritional inadequacy will only be noticeable to long term. These problems usually can be observed through the poor appearance of the dogs, obesity, abnormal blood pressure, renal failure, cancer, insulin resistance, hyperinsulinism and more.
High levels of fat in the diet recover the original food of dogs in nature. Besides having high digestibility, it leads the animal to a rapid state of satiety (reduce the consumption) and produces a very low glycemic response.
Diets with too much carbohydrate overload the pancreas that is required to produce high amounts of insulin to keep normal levels of plasma glucose (hyperinsulism). Fat is metabolically neutral and does not alter the level of glucose in the blood or induces the production of insulin. Proteins in diet have about 50% of their amino acids as glycogen (may result if necessary in the synthesis of glucose) and minimally induce the production of insulin.
A rich diet in 34% crude protein and 20% fat is the closest food to the original of dogs.
A rich diet in carbohydrates leads to an increase of daily consumption compared to a diet with high percentage of protein and fat. The increase of consumption has resulted in a greater volume of feces and more viscous, increasing the chance of gastric torsion, causing a situation of palatability and digestibility, which could increase the probability of obesity. In contrast, a diet of high percentage of protein and fat, reduces the consumption of food (about 33% of consumption per day - Chart 01), less probability to gastric torsion, reducing the volume of feces, stool consistency improved, high palatability (palatability = preference = consumption), 13% of reduction of caloric consumption a day (Table 03), besides being the closest food to the original of the dogs.
We can observe in Chart 01 and Table 02 high levels of protein and fat in food that supplies the daily needs of dogs with a lower amount of food consumed. The energy consumed is more skillfully exploited because the source is the fat and protein consumed does not exceed the limits required of the dog.
