Fat metabolism.

Fats are part of the cytoplasm of cells, take a direct part in cell metabolism, are carriers of fat-soluble vitamins (A, D, E, K), participate in the body’s thermoregulation, and ensure normal digestion and absorption of nutrients in the intestines. The fats of the feed consumed by the animal, under the action of enzymes, are broken down in the intestine into glycerin and fatty acids. After absorption by their lymphatic system, the body synthesizes again the fat characteristic of this animal species. Only part of the fat enters the portal vein blood, which brings it to the liver, where it can be stored. Part of the fat that enters the body is broken down with the release of a large amount of heat and water, and part is transported to fat depots (subcutaneous fat, omentum, tissues surrounding the kidneys, etc.),

The animal’s body can synthesize fat from carbohydrates and protein. However, individual unsaturated fatty acids (linolenic, linoleic, arachidonic, etc.) are not synthesized in the animal’s body, therefore, they must be ingested with food. Violation of fat metabolism leads to serious diseases.
