Description
Technical field
The invention belongs to field of fodder, be specifically related to get along well in a kind of raising beef aliphatic acid, the especially feed of CLA (c9, t11-CLA), DHA content more.
Background technology
Fat is made up of saturated fatty acid and unrighted acid, and unrighted acid is divided into again monounsaturated fatty acids and polyunsaturated fatty acid, and polyunsaturated fatty acid mainly contains linoleic acid, leukotrienes, arachidonic acid etc.Polyunsaturated fatty acid is the important essential fatty acid of people, must supplement from meals.Various vegetable fat is the important sources of polyunsaturated fatty acid.
In polyunsaturated fatty acid, CLA (CLA) is linoleic a kind of isomer, and CLA is divided into c9 again, t11-CLA and t10, c12-CLA two kinds.Large quantifier elimination shows that CLA has scavenging free radicals, strengthens oxidation resistance and the immunocompetence of human body; Regulate blood cholesterol levels and triglyceride level, atherosclerosis, promote that fat oxidation decomposes; Promote human body protein synthesis, significantly increase myocardial myoglobin, the skeletal muscle myoglobin content of human body, enhancing development; Strengthen the mobility of cell membrane, anti-hemostatic tube corticohyperplassia, maintain the microcirculatory normal function of organ, maintain normal configuration and the function of cell, strengthen the vasodilation abilities of blood vessel; Effective adjustment blood viscosity, the effects such as expansion and lax vascular smooth muscle.At American-European healthy food circle, CLA has almost become the cure-all medicine of prevention modern civilization diseases, from anticancer to angiocardiopathy preventing, diabetes, in body weight control, is almost live in the indispensable healthy food of 21st century modern.
But there are some researches show, t10, c12-CLA may have much potential negative effect simultaneously, as C reactive protein level in body can be increased, oxidative pressure may be caused thus, reduce the sensitiveness of insulin and increase lipid peroxidation reaction, finally increasing the risk suffering from diabetes, reduce the content etc. of DHA in heart.And c9, t11-CLA then do not have above-mentioned negative effect.
The meat of ruminant and breast are the topmost natural origins of CLA, and CLA mainly c9, the t11-CLA contained by it.Therefore, although manually CLA can be synthesized on a large scale at present, must higher t10 be contained, c12-CLA because its technique determines it, so, from food, absorb natural conjugate linoleate be considered to safest selection.In normal production conditions ruminant food, the content of CLA is very low, and in meat, general content is at 0.2-0.5g/kg, in milk, be generally about 0.1-0.3g/kg.And the health-care effect of CLA will be given full play to, people once needs the CLA taking in about 0.2-0.3g, therefore needs the CLA content improved by external source method in beef.
DHA, DHA (C22:6 ω-3), is commonly called as docosapentaenoic acid, is a kind of to the very important unrighted acid of human body, belongs to the important member in omega-3 unsaturated fatty acid family.A kind of main component that DHA is nervous system cell growth and maintains is brain and amphiblestroid important composition composition, and the DHA content improved in beef has great importance.
At present, the report about the feed improving content of polyunsaturated fatty acid is less, and focuses mostly on the unsaturated fatty acid content improving milk.Reduce stearic milk cow forage and feeding method as patent 201310699348.X discloses health aliphatic acid in a kind of raising milk simultaneously.This method solve existing method of adding linseed in milk cow forage to the problem of weak effect improving ω 3 polyunsaturated fatty acid in milk, fish oil is added to ω 3 content of polyunsaturated fatty acid improving milk in dairy cow diet.Patent application 200910040632.X, discloses a kind of feed addictive improving milk cow dairy food quality and anti heat stress for milk cow, and this feed improves the content of the unrighted acid in milk by directly adding calcium conjugated linoleic acid.In a word, the mode improving content of polyunsaturated fatty acid in milk is at present all directly add the single raw material being rich in unrighted acid, weak effect.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of feed improving content of polyunsaturated fatty acid in beef is provided.This feed adopts and splits kettle algae powder and the sunflower seeds main source as unrighted acid, adopts apple ground-slag to regulate palatability, improves digesting and assimilating of unrighted acid with bile acid.Pass through content of polyunsaturated fatty acid in the beef of the beef cattle that this feed is fed, especially the content of CLA, DHA is significantly improved.
