The vitamin premix of a kind of tilapia health improving tool metabolism syndrome and application
Technical field
The present invention relates to a kind of feed additive, particularly relate to a kind of tilapia health improving tool metabolism syndrome
Vitamin premix and application.
Background technology
The development of modern aquaculture be unable to do without the contribution of aquatic feeds, but in actual production, nearly all can send out
The Fish of existing various feedstuffs of ingesting the most likely occur that coefficient of condition is higher, intestinal expand thinning, visceral fat accumulation too much, blood
Analysis of Biochemical finds that Hyperlipemia, transaminase activity raise, and liver tissue slices finds swelling of liver cell, fat vacuole
The symptom of serious metabolism syndrome.This symptom be commonly due to feedstuff constitute unreasonable, throw something and feed excessive, poisonous
The factors such as the murder by poisoning of harmful substance.And have the fish of this symptom, resisting impact such as the water temperature acute variation, water quality ripple of poor environment
Move, when drawing in the net, easily caught by harmful microbe invasion and attack;Simultaneously, it is also possible to show the intolerance of transport, draw
The stress such as net overresponse, even there will be large quantities of death.For this problem, current solution is mainly passed through
Change feed formula, reduce feeding volume, utilize the modes such as Chinese herbal medicine conditioning to carry out, and lack fish nutrition after this problem occurs
Concern in terms of material aspect change.
Vitamin is to maintain a class nutrient substance necessary to fish bulk-growth and health.This kind of material is in vivo neither structure
Become the raw material of bodily tissue, be not the source of energy, but a class Auto-regulator, its important function in substance metabolism.As
Vitamin A has the dead effect with heat generation of active program sexual cell, is important fatty tissue growth regulator.Dimension
Raw element B1、B2、B6、B12, pantothenic acid, nicotiamide and biotin in sugar, protein, fat and energy metabolism, play important work
With.Wherein, vitamin B1Form the coenzyme of multiple branched-chain keto acids dehydrogenase in vivo, be oxidative deamination process in tricarboxylic acid cycle
Required composition;Vitamin B2It is the required ingredient of respiratory chain flavo-enzyme, biological oxidation transmits hydrogen;Nicotiamide is at body
Interior synthesis DPNH, and provide proton for oxidative phosphorylation process;Pantothenic acid is the ingredient of coenzyme A, is fatty acid oxygen
Change required material;Biotin is as the coenzyme of decarboxylase, involved in sugar heteroplasia and fatty acid oxidation.Vitamin C promotes fat
Fat is converted into energy, participates in fat and energy metabolism.Vitamin D is by the internal calcium metabolism of regulation and suppresses parathyroid hormone,
Cell Ca2+ influx, suppression obesity is avoided to occur.Vitamin E is important antioxidants, protects low density lipoprotein, LDL (low
Density lipoprotein, LDL) not oxidized.
But, this kind of material can not synthesize or synthetic quantity is not enough due to internal, so while requirement is little, but must be through
Often by food supply.But, along with the change of Fish physiological situation, the absorption of this type of material or metabolism can occur exception.People
In class medical science, as under fat state, there is various nutrients and lack in fat or overweight patient.Multivitamin, mineral exist
Fat generation, development play very important effect.Vitamin and mineral deficiency may result in the generation of obesity-related disease.
Auxiliary as weight intervention is treated, and supplements multivitamin and mineral contributes to controlling body weight, reducing body fat and whole body oxygen
Change stress, reduce obesity-related disease occur.But in Fish, carry out the most completely about research in this respect.
Tilapia is a kind of global important economic freshwater Fish, is excellent to world-wide deployment of FAO (Food and Agriculture Organization of the United Nation)
Good cultured fishes, become international one of main cultivation object.Over nearly 5 years, China mainland tilapia cultured output is about
1500000 tons, in freshwater aquiculture yield, occupy the 6th.It has the advantages such as feeding habits are miscellaneous, growth is fast, lower oxygen concentration resistance, premunition are strong.But
In breeding process, also will often find that fish body stomach fat is accumulated in a large number, the metabolism syndrome symptoms such as liver is loose.Existing grind
Study carefully that report is many to be solved in terms of Chinese medicine, Western medicine and pharmacology, and it needs the pass of change of vitamin under state to itself
Note less.Meanwhile, in the mixed feed of tilapia, conventional vitamin premix mostly is with under fish body healthiness condition, presses
Value according to the nutritional need meeting maximum growth rate is prepared.It was also found that Fish are occurring metabolism to combine in reality cultivates
During simulator sickness, a small amount of mixed feed manufacturer is had to have reached to improve by the way of increasing the addition of vitamin premix
The effect of part fish body health status, this effectively illustrates that vitamin is to tool metabolism syndrome under this kind of unsound state
The importance of symptom healthy fish, but this interpolation has randomness and uncertainty, such as whether mean all vitamins
Component will increase, and the most only needs the problem such as content increasing some vitamin the most on the knees of the gods.
