Abstract

The invention discloses a method for producing endogenous selenium-rich vitamin-E-rich raw milk. The method is characterized in that selenium-rich yeast and vitamin E are added into basic ration used for feeding dairy cows, and the dairy cows can convert and produce the endogenous selenium-rich vitamin-E-rich raw milk. The content of selenium and vitamin E in the endogenous selenium-rich vitamin-E-rich raw milk obtained by the adopting the method disclosed by the invention is much higher than that of common milk, is good functional milk and is different with the milk containing selenium and vitamin E which are added after the milk is obtained, the selenium and vitamin E which are produced by metabolism can be better absorbed by people, and the method disclosed by the invention is simpler.

Description

The rich selenium of endogenous, rich vitamin E raw material milk production method

Technical field

The invention belongs to the dairy produce field, specifically, relate to the functional milks production method of the rich selenium of a kind of endogenous property, rich vitamin E.

Background technology

Be accompanied by the growth day by day of global functional health-care food consumption and the increase that milk nutrition is familiar with, functional milk-supply progressively becomes new bright spot on the milk market.Function milk as its name suggests, is exactly the milk specific to some function.It can increase iron for the people of anaemia, and the people that need replenish the calcium for pregnant woman's grade strengthens calcium, also can control people's production degreasing or low fat milk of body weight etc. for needs.At present, the function milk of world's dairy products market popularity has had a variety of.

Selenium and vitamin E have collaborative antioxidation; Vitamin E is keeping cell membrane to avoid playing compensation and coordination with Se aspect the oxidative damage; Vitamin E is positioned on the cell membrane, and diaphragm is avoided free radical attack and peroxide injury, is oxidation resistant the first line of defence.And selenium destroys peroxide through the GSH-Px that is present in the cell liquid, prevents that the formation of harmful free radical from reaching unsaturated fatty attack, is the defence line, second road in the body.GSH-Px decomposes established peroxide and has stoped the generation that possibly cause the snperoxiaized HO-of membrane lipid and singlet oxygen-O2.And the generation of vitamin E block film lipid peroxidation chain reaction minimizing hydroperoxides shows " saving each other " effect between them.Selenium and VE also have tangible promotion effect to body panimmunity function.

Summary of the invention

For solving above technical problem, the object of the present invention is to provide the production method of the rich selenium of a kind of endogenous, rich vitamin E raw material milk.

The present invention seeks to realize like this: the rich selenium of a kind of endogenous, rich vitamin E raw material milk production method; Its key is: the Se-enriched yeast and the vitamin E that in the basal diet that milk cow is fed, add, milk cow will transform the rich selenium of output endogenous, rich vitamin E raw material milk.Experiment can prove that selenium contained in milk is the selenium that is beneficial to absorption, is not that the selenium that adds feed simply directly is transformed in the milk.The selenium compound of solubility is easy to absorbed by animal, and selenium major part contained in the milk is the selenium compound of solubility, utilizes after can being converted into inorganic selenides behind the entering animal body.In the milk contained selenium be selenium in the feed through absorbing, participate in getting in the mammary gland behind some amino acid metabolisms, the formation of participating in milk is secreted at last and.Contained selenium and the vitamin E in the milk of output the inside absorbed by the people more easily like this.

Milk cow of above-mentioned every nursing adds Se-enriched yeast and vitamin E in daily ration amount is that selenium 0.5mg/kgDM adds vitamin E 100IU/kg DM.Select this addition definite, the level of Ruzhong selenium and vitamin E is significantly improved, can not cause in the milk cow body again and accumulate through testing.

Above-mentioned milk cow is fed three times every day, and the daily ration of feeding each time is 3.0～3.2% of a milk cow body weight.

Said by mass percentage daily ration consists of

Green hay 23.50%

Corn silage 20.75%

Corn 30.10%

Wheat bran 5.02%

Big dregs of beans 4.68%

The cottonseed dregs of rice 6.69%

DDGS4.18％

Sesame seed meal 0.84%

Calcium monohydrogen phosphate 1.11%

Calcium carbonate 0.84%

Sodium bicarbonate 0.67%

Magnesia 0.39%

Salt 0.56%

Additive premix 0.56%

Mould inhibitor 0.11%.

(1) china holstein cows of selection 16 the first-borns time unanimity, lactation mid-term (60-150d) adopts the completely randomized experiment design, is divided into 2 groups.One group is control group, the basal diet of feeding; Another group is processed group, and the basal diet+Se content of feeding is that Se-enriched yeast+content of vitamin E of 0.5mg/kg DM is the DL-alpha tocopherol acetate of 100IU/kgDM.Se-enriched yeast is the happy selenium Sel-Plex of match that U.S. Ao Teqi biotech company produces, and Biological Selenium content is 2000mg/kg in this product.DL-alpha tocopherol acetate is the Luo Shi board product that is provided by DSM N. V., and the content of vitamin E is 90% in this product.

Experimental period is 60 days, and wherein preliminary trial period 10d is just trying phase 50d.Measure selenium and content of vitamin E in milk production, newborn conventional ingredient content, cow's milk and the blood plasma just trying the 1st day phase, the 10th day, the 20th day, the 30th day, the 40th day and the 50th day respectively.

The basal diet composition is identical with the test of adding organic selenium with the feeding and management of trophic level and test ox.

(2) result of study

Visible by table 1, behind interpolation Se-enriched yeast and the DL-alpha tocopherol acetate, processed group is compared with control group in the diet, and milk yield, butter oil, lactoprotein, lactose all do not have marked change (P＞0.05).

The variation of lactating cow milk yield, newborn conventional ingredient behind interpolation Se-enriched yeast and the vitamin E in table 1 daily ration

Visible by table 2, behind interpolation Se-enriched yeast and the DL-alpha tocopherol acetate, the content of processed group blood plasma and newborn selenium and the vitamin E all utmost point is significantly higher than control group (P＜0.05) in the daily ration.Processed group is compared with control group, and Se content has improved 54.1% in the ox blood slurry, and Se content has improved 75.9% in the cow's milk, and content of vitamin E has improved 53.8% in the ox blood slurry, and content of vitamin E has improved 148.0% in the cow's milk.

Add Se-enriched yeast and vitamin E in table 2 daily ration to milk cow's milk and blood plasma Se content (μ g/L)

Influence with content of vitamin E (μ g/mL)

(3) brief summary

1. interpolation Se-enriched yeast and DL-alpha tocopherol acetate can not make significant difference to the output of milk and the conventional component content in milk of milk cow in diet.

2. interpolation Se-enriched yeast and DL-alpha tocopherol acetate can significantly improve selenium and content of vitamin E in blood plasma and the cow's milk in diet.

Beneficial effect: the rich selenium of the endogenous that the inventive method obtains, rich vitamin E raw material milk selenium and vitamin E are more much higher than common milk; It is extraordinary functional milks; And with become milk after add again different; This selenium and vitamin E through output after the metabolism more can absorb the people, and this method is also fairly simple.
