Utilização de ômega 3 e 6 na alimentação de cães.

Abstract

The absence of essentials nutrients in the future brings diseases that can compromise not only the health, but the life of the animals. Fatty acids (AG) are lipid components and are distributed in all tissues, mainly in cell membranes and fat cells. Among these, those classified as essential as the polyunsaturated fatty acids n-3 and n-6. The fetus and even the puppies after the first days of birth are not able to synthesize long-chain polyunsaturated fatty acids (ômega 3 and 6), and their need is met by the placenta and the dog's milk if supplemented. Growing puppies need a percentage of 0.08% alphalinolenic acid. Maintenance dogs need a lower percentage. The omega 3 and 6 fatty acids act in the supply of concentrated energy, energy reserve in the animal organism, source of essential fatty acids, important for the nervous system, natural insulator to the environment. Its absence can cause, reduced growth, worse feeding efficiency, dry skin, dermatitis, hair loss, delayed sexual maturity, less fertility, accumulation of fat in the liver, less recovery in periods of convalescence, low resistance to various diseases such as coronary and cancer. These acids have unsaturations separated by a methylene carbon and listed from the final methyl group, and can also be listed from the carboxyl according to the delta designation using the nutritional designation n. Acids can also influence triglyceride and cholesterol levels. These are also responsible for the production of eicosanoids and prostaglandins. The objective was to carry out a bibliographic review on the use of fatty acids in the nutrition of dogs, seeking to document the development of research in relation to this essential nutrient.
