Description
Technical field
The present invention relates to a kind of method feed, relate in particular to a kind of high omega-3 fatty acid poultry feed and preparation method thereof, belong to the poultry feed field.
Background technology
The egg duck breed amount of China accounts for whole world egg duck and cultures about 70% of total amount, and the edible duck's egg of people has excellent history of a specified duration.Much more more and more China's egg duck industry development is rapid, and duck's egg has higher nutritive value because of it, to be subjected to people's favor.Protein content is the same with egg in the duck's egg, and protein almost all is 45～70 grams in per 500 gram eggs or the duck's egg, but the fat in the duck's egg is abundanter than egg with mineral matter, and the fat in the 500 gram duck's eggs can surpass 70 grams.Total amount as for various mineral matters in the duck's egg is more a lot of above egg, and particularly iron that presses in the health and calcium are abundant especially in duck's egg.Vitamin b2, in duck's egg than Duoing more than 1/5 in the egg.The traditional Chinese medical science thinks that the duck's egg flavor is sweet, cool in nature, and the effect of big qi-restoratives labor, nourishing yin and nourishing blood is arranged.To the oedema turgor, diseases such as deficiency of Yin insomnia have certain therapeutic action.Omega-fatty acid (polyunsaturated fatty acid) is the necessary class aliphatic acid of human body, since the seventies in last century, the Eskimos that scientist has found to live in Greenland seldom suffers from angiocardiopathy and begins, and people to omega-fatty acid research beginning progressively deeply.In the last thirty years, the various countries scientist puts in the omega-fatty acid research one after another, surpasses 1.5 ten thousand parts of research reports and shows, omega-fatty acid has anti-inflammatory, antithrombotic formation, the formation of the anti-rhythm of the heart, reduces blood fat, vasodilatory characteristic.Human body is taken in essential omega-fatty acid, can effectively prevent and treat coronary heart disease, diabetes, rheumatoid disease, dermatitis, cancer card, senile dementia, depressed card, allergy, stomach trouble etc., and children's intelligence and retinal development are also had suitable effect.If replenish omega-fatty acid every day, evidence of coronary heart diseases will descend 80%, and the sudden death rate is with decline 40-50%.Although omega-fatty acid is human essential nutrition, can not self synthesize in people's the body, must from food, obtain.Chinese American, aliphatic acid research center director doctor Kang Jingxuan of Harvard University point out, aliphatic acid and vitamin, amino acid are the same, are one of most important nutrients of human body, and omega-3 polyunsaturated fatty acids is that human body self can't synthesize.
Birds, beasts and eggs are the often edible a kind of foods of people, and birds, beasts and eggs have allows an embryonic development become a necessary all nutrients of life entity, so the contained the most suitable human needs of nutriment in the birds, beasts and eggs.But poultry is when producing birds, beasts and eggs, many compositions of feeding in the feed of poultry all are easy to be enriched in the birds, beasts and eggs, omega-fatty acid also is a kind of material that is easy to be enriched in the birds, beasts and eggs, so people utilize this accumulation ability of poultry to produce the high omega-3 fatty acid birds, beasts and eggs.
In order to improve the content of omega-fatty acid in the birds, beasts and eggs, existing method adopts following several method: (1) is rich in the birds, beasts and eggs of omega-fatty acid with the poultry acquisition of feeding of the single or mixture of fish oil, fish pomace, fish meal, fish oil extract.But fish oil, fish pomace, fish meal or fish oil extract all are the comparatively expensive raw materials of price, use this this raw material to produce ω-3 birds, beasts and eggs and can increase production cost greatly, secondly, the fish raw material is fed behind the poultry, the birds, beasts and eggs of being produced have denseer fishy smell, have a strong impact on especially infant's mouthfeel of people, long-term edible, may cause detest even the food refusal of eater to birds, beasts and eggs.(2) obtain the omega-fatty acid birds, beasts and eggs with the extract of microorganism with the ability that produces omega-fatty acid or microorganism the poultry of feeding.The microbe species that can produce omega-fatty acid is few, cultivation by microorganism, then with the extract of microorganism or microorganism the poultry of feeding, the process complexity, the expense height, and the microorganism that can produce omega-fatty acid is not normal microorganism in the animal body, because of this microorganism in body of animal can not be synthesized omega-fatty acid, after microorganism in these improper bodies enters in the animal body, might produce original microorganism species and disturb or destruction.
If use the feedstuff of some animalities poultry of feeding, have a kind of strong fishy smell in the birds, beasts and eggs of being produced, cause people to dislike edible birds, beasts and eggs.How allowing the omega-fatty acid of the existing high-load of birds, beasts and eggs, do not produce fishy smell again, is to produce the difficult problem that the high omega-3 fatty acid birds, beasts and eggs will solve.
