Description
Technical field
The invention belongs to field of fodder, and in particular to more discord aliphatic acid in one kind raising beef, especially CLA (c9,
T11-CLA), the feed of DHA content.
Background technology
Fat be made of saturated fatty acid and unrighted acid, unrighted acid be divided into again monounsaturated fatty acids and
Polyunsaturated fatty acid, polyunsaturated fatty acid mainly have linoleic acid, leukotrienes, arachidonic acid etc..Polyunsaturated fatty acid
It is the important essential fatty acid of people, it is necessary to supplemented from meals.Various vegetable fat are the important sources of polyunsaturated fatty acid.
In polyunsaturated fatty acid, conjugated linoleic acid (CLA) is a kind of linoleic isomer, and CLA is divided into again
C9, t11-CLA and t10, two kinds of c12-CLA.Substantial amounts of research shows that CLA has and removes free radical, strengthens the anti-oxidant of human body
Ability and immunocompetence；Adjust blood cholesterol levels and triglyceride is horizontal, atherosclerosis, promotes fat oxidation point
Solution；Promote human body protein synthesis, dramatically increase myocardial myoglobin, the skeletal muscle myoglobin content of human body, promote growth hair
Educate；Strengthen the mobility of cell membrane, anti-hemostatic tube corticohyperplassia, maintains the normal function of organ microcirculation, maintaining cell just
Normal structure and function, strengthen the vasodilation abilities of blood vessel；Blood viscosity is effectively adjusted, expansion and relaxation vascular smooth muscle etc. are made
With.In American-European healthy food circle, CLA is almost into the cure-all medicine of prevention modern civilization diseases, from anticancer to prevention of cardiovascular
Disease, diabetes, onto body weight control, almost live in the indispensable healthy food of 21st century modern.
But some researches show that t10, c12-CLA may have many potential negative effects at the same time, can such as increase internal C-
Reactive protein is horizontal, may thus cause oxidative pressure, reduces sensitiveness and the increase lipid peroxidation reaction of insulin, most
The risk of diabetes is suffered from increase eventually, reduces content of DHA etc. in heart.And c9, t11-CLA are then without above-mentioned negative effect.
The meat and breast of ruminant are the most important natural origins of conjugated linoleic acid, and the CLA contained by it is mainly c9,
t11-CLA.Therefore, although can manually synthesize CLA on a large scale at present, due to its technique determine its necessarily contain compared with
High t10, c12-CLA, so, it is considered as safest selection to absorb natural conjugate linoleate from food.Normally giving birth to
The content of CLA is very low in production condition ruminant food, and general content is in 0.2-0.5g/kg in meat, in milk generally
0.1-0.3g/kg or so.And the health-care effect of CLA is given full play to, people once needs to take in the CLA of 0.2-0.3g or so, because
This needs to improve the CLA contents in beef by external source method.
DHA, docosahexaenoic acid (C22:6 ω -3), docosapentaenoic acid is commonly called as, is a kind of to the very important unsaturation of human body
Aliphatic acid, belongs to the important member in omega-3 unsaturated fatty acid family.DHA is nervous system cell growth and the one kind maintained
Main component, is the important composition component of brain and retina, and the DHA content improved in beef has great importance.
At present, the report of the feed on improving content of polyunsaturated fatty acid is less, and focuses mostly on and improving milk
On unsaturated fatty acid content.Subtract at the same time as patent 201310699348.X discloses health aliphatic acid in a kind of raising milk
Few stearic milk cow forage and feeding method.It this method solve the existing method pair that linseed is added in milk cow forage
The problem of effect of 3 polyunsaturated fatty acids of ω is poor in raising milk, fish oil is added in dairy cow diet to improve milk
3 content of polyunsaturated fatty acid of ω.Patent application 200910040632.X, discloses a kind of raising milk cow dairy food quality and milk cow
The feed addictive of anti-heat stress, the feed improve the unrighted acid in milk by directly adding calcium conjugated linoleic acid
Content.In short, the mode for improving content of polyunsaturated fatty acid in milk at present is all directly to add single to be rich in insatiable hunger
It is poor with the raw material of aliphatic acid, effect.
