Technical field
The present invention relates to egg fowl field of fodder, relate in particular to a kind of feed addictive that improves birds, beasts and eggs DHA content.
Background technology
DHA, DHA, is a kind of Ω-3 essential fatty acids, is commonly called as " docosapentaenoic acid ".It is that people's brain development is, one of important substance of growth, it is a kind of essential element that nervous system cell is grown and maintained, brain and amphiblestroid important composition composition, in human brain cortex, content is up to 20%, in eye retina, proportion is maximum, accounts for 50%, along with going deep into of research, DHA is day by day clear and definite for the importance of human body, and its unique effect has obtained common recognition widely.
On the one hand, DHA is as infant's growth factor, most important to the intelligence of tire cradle and visual acuity, with a very important position.Tire cradle, brain is in the stage of development, and DHA can promote the division growth of brain cell, the growth of " projection " and the formation of neutral net, thus cranial capacity is increased, brain internal information is processed and is accelerated, and is conducive to intelligence, the raising of learning and memory ability.DHA can also promote the physiogeny of infant's eye, if lack DHA, the DHA content on retina will reduce, and the visual sensitivity of light is just had to impact, and eyesight can reduce.Particularly at the retina of developmental stage, need the more DHA(of high-load to account under normal circumstances 50%), U.S.'s clinical nutriology magazine was once reported, baby starts the edible DHA(0.21g/L that added from birth) the milk powder of formula to one-year-old left and right, can improve baby at 6 weeks, 17 weeks, the visual sensitivity of 52 weeks.
On the other hand, DHA is adult's healthy element.Being described as is the ideal object of control senile dementia, is prevention and Cardiovarscular, anticancer change, the active principle of raising eye, brain, the power of being indecisive and changeable.
Human body self can not synthesize DHA, can only absorb from the external world.The World Health Organization (WHO), the World Food Programme (FAO), international aliphatic acid and lipoid EASD (ISSFAL), U.S. gestation association (APA), American-European food security office (EFSA), the Holland healthy committee (DHC), lifelong continuation picked-up is recommended by Japanese health welfare Ministry of Labour (MHLW) etc.The daily intake that the World Health Organization (WHO) is recommended is: the minimum intake of pregnant woman every day should be: 300mg, the minimum intake of Healthy People every day should be: 220mg, 100 milligrams of infant every days.
Just because it has so importance, on market, there is in decades numerous DHA products, generally, can be divided into first generation fish oil DHA (claiming again second fat type), the second generation algae oil DHA(claim again triglyceride type), the third generation yolk DHA(claim again lecithin type).Along with the development of technology and the raising of awareness, the market of third generation lecithin type DHA just constantly expands.Allow egg be rich in a kind of inevitable outcome that DHA is development.
Chinese patent CN101015321A, CN102907573A, CN10144256A, discloses three kinds of modes that improve DHA content in birds, beasts and eggs.Its common feature is all that to take terrestrial plant or extract be primary raw material composition, and effect is subject to the place of production, collecting season, and the impact of processing mode.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of feed addictive that improves birds, beasts and eggs DHA content.It is main material that feed addictive provided by the present invention be take the commodity of marine microorganism fungal fermentate, and technique is simple, and it is the most convenient to operate, and uniformity is strong, and addition is micro-, is desirable egg feed additive for fowls.
Improve a feed addictive for birds, beasts and eggs DHA content, comprise each component of following quality percentage composition: DHA microalgae powder 98～100%, additive auxiliary material 0～2%.
Preferably, described DHA microalgae powder is to split kettle algae (Schizochytrium sp.) or my Ken Shi kettle algae (Ulkeniaamoeboida) or the hidden dinoflagellate (Crypthecodiniumcohnii of Kou Shi, have another name called dino flagellate) or one or more in planting of thraustochytriale (Thraustochytrids) be raw material, no matter by fermentation, separated, dry, powder process and whether mix, what operation is mixed or powder process after the DHA microalgae powder that technique obtains such as mix.
Preferably, described additive auxiliary material is selected from one or more the mixing in trace mineral supplement, vitamin, synthesizing amino acid, antibiotic, antioxidant, mould inhibitor, pest repellant.
Trace mineral supplement refers to the nutritional substance of microelement-supplementing deficiency in natural feed.The mineral matter element that animal is essential, mainly contains 16 kinds.Conventionally percentage of liveweight more than 0.01% is called to constant mineral matter element, as sodium Na, magnesium Mg, potassium K, calcium Ca etc.; Mineral matter element percentage of liveweight below 0.01% is called trace mineral element, as selenium Se, iron Fe, copper Cu, manganese Mn, zinc Zn, iodine I etc.
Preferably, described antioxidant is selected from one or more the mixture in citric acid, vitamin E, butylated hydroxy anisole (BHA), ethoxyquinoline (EMQ) etc.
The present invention also provides a kind of poultry feed, is added with the provided by the present invention described feed addictive that accounts for described poultry feed gross mass percentage composition 0.8%～3.0% in described poultry feed.
