What do you value when choosing a feed for your pet? Do you consider the origin of the proteins contained in food? Currently, we have at our disposal a lot of information about dog feeding.
We know that there are certain products that end up producing organic damage to our dogs or nutritional deficiencies, some of them quickly detectable because the dog begins to eat inedible products, such as walls, shoes, or its own excrement, when it had never done so before.
In the first place, we must know what the digestive system of dogs looks like and that they are not omnivorous animals, but optional carnivores.
Therefore, the main protein contribution of our pet should be meat and not cereal grains. What is the origin of the protein that your pet ingests? Did you ever think about the biological value of the proteins contained in food? We tell you!
What is the biological value?
Proteins are formed by binding a type of bond called a peptide, by amino acids. Each protein has a different composition of amino acids, and, in addition, there are essential amino acids that the body is not able to synthesize and can only be acquired through the diet.
In the dog, there are 12 essential amino acids, which are the following: arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan, threonine, and valine.
The biological value of the proteins contained in food is the ability of a protein, existing in the diet, to be incorporated into body proteins. In other words, the biological value of the protein is the willingness to be absorbed and assimilated.
How does it affect the biological value of the proteins contained in food?
To take advantage of the proteins contained in food, we must first look at its origin, in addition to the type of processing they have suffered. Many of the feeds that are currently marketed have as a source of protein flour of animal origin, mainly poultry flour.
The problem of this raw material lies in its heterogeneity, and, in addition, after the extruded process that the feed undergoes, the protein value drops.
When we give our pets this type of feed, we are not providing a quality diet. These proteins are of little biological value. For this reason, they also add to feed, cereals – such as corn and rice – and other sources of protein, to increase protein intake.
On the other hand, the extrusion of food also decreases the quality of the fatty acids contained in them. This is because they increase the amount of unsaturated fatty acids and unbalance the ratio.
Better feed for dogs
When we have to choose a feed for our pet, many doubts may arise about which will be the best and, consequently, we tend to think that the best I think is the most expensive. This is not entirely true.
Certain brands of dog feed are more expensive because they have a high advertising expense. However, their feed is not the best if we look only at its composition and the origin of its ingredients.
If we want to choose a good feed for our pet, we will consider a series of premises:
- A good feed always shows the exact origin of its ingredients. For example, it is better to choose a feed that specifies that its meat is from wild boar to another that only tells us ‘poultry meat.’ In addition, if you do not indicate the word ‘meat,’ you can include any part of the animal, such as viscera, tendons, skin, etc.
- There are feedstuffs that include hydrolyzed meat. This processing causes the biological value of the protein to increase.
- Once the origin is known, we will observe the type. Used meat must be dehydrated or fresh. If we choose a feed made with fresh meat, we must subtract the amount of water that meat contained in the protein percentage. Therefore, a feed with fresh meat is no better than another with dehydrated meat.
- A feed may contain cereals. It’s not that dogs can’t get nutrients from these ingredients; The problem is that sometimes rice or corn is the second or third ingredient of the feed, and that does mean that the feed is not of quality.
- Better legumes instead of cereals.
- The origin of the fats added to a feed should also be known. If you use vegetable oils, we must observe that they are not refined. This negatively affects the omega 6 / omega-three ratios, which should be close to 1.
- Finally, many feeds include vegetables among their ingredients. This is not negative because they provide fibers, very necessary for intestinal transit and essential vitamins.
Now you know how to know the biological value of the proteins contained in dog food and how to choose the best diet for dogs. Remember that taking care of your diet is synonymous with health and happiness for your pet.
