The source of dietary at influences the fatty acid composition in poultry
Sponsored LinksThe fats are bimolecular group of compounds related, either actually or potentially, to the fatty acids. They have the common property of being relatively in soluble in water and soluble in non-polar solvents such as ether, chloroform, and benzene.
Fat are important dietary constituents not only because of their high-energy value but also because of fat-soluble vitamins and essential fatty acid contained in the fat of natural foods. Inter body, fat serves as an efficient source of energy-both directly and potentially, when stored in adipose tissue. It serves as a thermal insulator in the subcutaneous tissue and around certain organs, the fat content of nerve tissue is particular high. Combinations of fat and protein (lipoproteins) are important cellular constituents, occurring both in the cell membrane and in mitochondria within the cytoplasm, and serving also as the means of transporting lipids in the blood.
The source of dietary at influences the fatty acid composition of adipose tissue in poultry species. Broiler chickens as increase of adipose tissue in the diet contain saturated fatty acid, SFA (tallow) but soybean, sunflower, and rapeseed oils (high in unsaturated fatty acid, UFA) caused an decrease in the adipose tissue. The functions of the UFA appear to be various, though not well defined, apart from prostaglandin formation. The UFA are found in the structural lipids of the cell, are concerned with the structural integrity of the mitochondrial membrane, and occur in high concentration in the improved average body weight gain, feed efficiency, but not effect to feed intake. The effect of UFA on regulation of lipid metabolism and the level and composition of body fat appear to be diverse. Vegetable oils containing high levels of UFA, such as soybean oil, are known to inhibit lipogenesis. It has been reported recently that soybean oil supplementation depresses body fat in broiler chickens selected divergently for high or low abdominal adipose tissue content. Fat Levels in dietary improved to average daily gain, feed per gain. However, carcass lipids were follow fat levels in diets.
