The production method of poultry
What the present invention relates to is the feed addictive composition of a kind of production method of poultry, especially fowl.
Eicosapentaenoic acid (EPA) and DHA (DHA) have irreplaceable effect to fetus and infant's intelligence and eyesight growth, are the nutriments that pregnant woman and infant must take in; Simultaneously anti-angiocardiopathy, inhibition tumour etc. also there is bigger effect.Can treat hyperlipemia, slight senile dementia, anaphylactia, and cholesterol reducing is arranged, improve the function of eyesight.Containing a large amount of ω 3 in the fish oil is polyene unsaturated fatty acid (ω 3-PUFA), and ω 3 be most of final metabolite of polyene unsaturated fatty acid is eicosapentaenoic acid and DHA, so fish oil has become a kind of important health products.But fish oil does not make it to be difficult to bring into play its effective function because of its fishy smell heavily makes people's apocleisis and human body to its digestibility is high.Poultry is to produce by the raising to fowl, and the feed composition of the composition of poultry and fowl has a kind of relation, promptly contains the metabolite of composition in the fowl body in the feed in the poultry.Contained eicosapentaenoic acid and the DHA of general poultry is not high, and does not still have the poultry production of being rich in eicosapentaenoic acid and DHA at present.
For remedying above-mentioned deficiency, purpose of the present invention is exactly the production method that a kind of poultry will be provided, and makes the poultry that is obtained contain abundant eicosapentaenoic acid and DHA.
The production method of poultry provided by the present invention, it is the relation of utilizing the feed composition of the composition of poultry and fowl, fish oil is added on as feed addictive in the feed of fowl, and its addition is counted the 0.5-8% (weight) of feed with pure eicosapentaenoic acid and DHA.Generally add with fish oil concentrated, powdered, it contains pure eicosapentaenoic acid and DHA is about 50% (weight).
The poultry that production method obtained by poultry provided by the present invention contains abundant eicosapentaenoic acid and DHA owing to it, make people in edible this poultry, can absorb eicosapentaenoic acid and DHA, exempted to absorbing the taste discomfort that eicosapentaenoic acid and DHA feed fish oil brings, improved the absorption of human body simultaneously eicosapentaenoic acid and DHA.The production method of poultry provided by the present invention, eicosapentaenoic acid in its poultry of producing and DHA content increase with the increase of the fate of the feed that is proposed among the present invention of fowl feeding, can improve more than 3~4 times in general 5 days.
The production method of poultry provided by the present invention, the addition of fish oil in the fowl feed more reasonably are to be the 1.5-5% (weight) of feed in pure eicosapentaenoic acid and DHA, and the best is 2.5% (weight) for feed.
The production method of poultry provided by the present invention is applicable to all fowl, as chicken, quail, duck or the like.
Embodiment 1: with containing the 5% powdered fish oil forage feed quail of (containing eicosapentaenoic acid and DHA 50%), pure eicosapentaenoic acid and the DHA changes of contents of the quail meat that produces are as follows: content mg (EPA+DHA)/quail meat of g contains EPA+DHA and measures 0 0.255 45.26 5 0.816 146 60 12.91 2234 in the nursing fate quail meat
Embodiment 2: with containing the 3% powdered fish oil forage feed chicken of (containing eicosapentaenoic acid and DHA 50%), the pure eicosapentaenoic acid and the DHA content of the chicken that produces are as follows: feed content mg (EPA+DHA) in a fate chicken/chicken EPA+DHA amount of g (mg) 0 0.27 256.5 5 0.98 936.88
Embodiment 3: with containing the 5% powdered fish oil forage feed duck of (containing eicosapentaenoic acid and DHA 50%), the pure eicosapentaenoic acid and the DHA content of the duck that produces are as follows: feed content mg (EPA+DHA) in a fate duck/duck EPA+DHA amount of g (mg) 0 0.202 157.96 60 11.23 8804.32
