What is in dog food?
We usually divide the materials that can be used as dog feed into three categories according to source: animal feed, plant feed and mineral feed. Most dog foods mainly include these three parts.
- Animal feed refers to a type of feed derived from animal bodies, including meat, offal, blood meal, bone meal, eggs, and milk of livestock and poultry. Animal feed occupies an important position in dog diets and can provide dogs with high-quality protein, fat and minerals. Protein and fat provide the necessary energy for dog activities, while protein is also an important raw material for building and repairing the body.
- All plant-derived feeds are plant-based feeds, including seeds of crops (such as rice, soybeans, corn, wheat, potatoes, and sweet potatoes, etc.), and by-products after crop processing (such as bean cake, peanut cake, sesame cake, rice bran, etc. ) And vegetables. Plant-based feed is also the main component of dog food. It is rich in carbohydrates, cellulose, vitamins, minerals, starch, etc. In addition, it also contains more organic acids and phytobacteria. All in all, plant-based feed can help stimulate bowel movements, reduce diarrhea and constipation in dogs, and help improve digestion.
3. Generally speaking, there is a certain mineral content in animal and vegetable feeds. Due to the diversity of dog food, the mineral elements in animal and plant feeds can often supplement each other to meet the needs of dogs for most minerals. . However, for certain mineral elements with high demand, such as calcium and sodium, when the feed cannot meet the needs of the dog, the mineral feed needs to be added separately.
