Description
Technical field
The present invention relates to the mode of production and the feed thereof of a kind of n-3 of being rich in polyunsaturated fatty acid (n-3PUFA) foie gras, belong to the animal feeding technical field.
Background technology
Studies confirm that of recent two decades, n-3 polyunsaturated fatty acid (n-3PUFA) has physiological function and biological effect more widely in body, two keys the more, degree of unsaturation is higher, nutritive value is also higher.N-3PUFA mainly comprise alpha-linolenic acid (ALA, C18:3n-3) and long-chain metabolin eicosapentaenoic acid (EPA, C20:5n-3) and DHA (DHA, C22:6n-3).N-3PUFA is various histocyte membrane phospholipid important structure components in the body, and cell membrane function and characteristic have material impact (Muriana etc., 1992; Berlin etc., 1992); Human body had beneficial effects (Simopouolos, 1991) such as reducing the cardiovascular and cerebrovascular incidence of disease, promote brain development, be antitumor; N-3PUFA, especially the content of DHA in central nervous system and retina cell's phosphatidyl ethanolamine is abundant, is the important substance (Neuringer etc., 1988) that promotes neurodevelopment and keep visual performance; EPA is commonly called as and is " blood vessel street cleaner ", has the function of the rubbish (cholesterol and triglycerides) in the cleaning blood vessel.In addition, n-3PUFA to anti-inflammatory, strengthen immunity also play an important role (Liu, 2003).Therefore, in recent years, the animal products that is rich in n-3PUFA by the exploitation of nutrition means becomes hot research in recent years (Kouba etc., 2010), improves the content of n-3PUFA in the livestock products, for the mankind provide the meals that are rich in n-3PUFA significant.
