Problems solved by technology

However, the addition of organic selenium in the process of dairy product processing cannot be fully absorbed by the human body, and the best effect on nutrition and health care cannot be achieved. The best way to produce selenium-enriched dairy products is to make cows secrete selenium-enriched raw milk
Although there are some selenium-enriched cattle feeds in the prior art, only by using these selenium-enriched cattle feeds to raise dairy cows according to the traditional method, the obtained milk cannot reach the selenium-enriched milk content required by the state, and the selenium-enriched milk cannot be sustained and stable for a long time. Production
Therefore, still lack a kind of scientific dairy cow breeding method of producing selenium-enriched milk at present

Embodiment 1

[0041] Example 1 Screening of the most suitable selenium source

[0042] The inventors selected 10 types of 2 types of yeast selenium products on the market. Among them, one type of organic selenium sources are mainly Candida utilis and Candida tropicalis; the other type, organic selenium sources are mainly Saccharomyces cerevisiae. Selenium-enriched yeast was added to the conventional feed at a dose of 30 mg / head, and each product was fed to 10 dairy cows entering the lactation period for 30 days. The selenium content in the milk produced by the cows during and after the feeding was determined during the feeding process. The results showed that the content of selenium in milk produced by cows fed with selenium-enriched yeast from Candida utilis and Candida tropicalis did not change significantly. However, the changes of selenium in milk produced by cows fed with organic selenium derived from brewer's yeast were significant. Among them, the experimental group fed with Selen...

Embodiment 2

[0044] Example 2 Production test of selenium-enriched milk with different yeast selenium additions

[0045]In order to sample the long-term feeding effect of adding selenium-enriched yeast and the production stability of selenium-enriched milk produced by dairy cows, in this example, the inventor selected 844 healthy, normal growth and development lactating dairy cows. Based on the principle of similar calf days, the experimental cows were divided into 4 experimental groups with 211 cows in each group. The control group was fed selenium-enriched fungus chaff feed, and the low-dose organic selenium, medium-dose organic selenium and high-dose selenium supplemented groups were fed. Feed different levels of yeast selenium. Different selenium sources were evenly mixed into the feed for feeding. The specific experimental groups are:

[0046] Test grouping:

[0047] The amount of organic selenium fed in the diet of the low selenium dose selenium supplement group: 5-10 mg / head day....

Embodiment 3

[0063] Example 3 Stability test of dairy cows producing selenium-enriched milk

[0064] In order to solve the problem of poor stability of selenium-enriched milk produced by dairy cows and large fluctuation of selenium content in milk. The inventors made adjustments to the cow feeding process during lactation. The experiment selected 726 healthy, normal growth and development lactating dairy cows. According to the principle of similar age, parity, milk production and calving days, there were 4 cowsheds in the experimental group, with 182 cows in each group. The dosage of organic selenium was selected as The middle dose group of Example 2. During the feeding process of the previous year, the inventor accidentally found that the content of selenium in the milk produced by changing the dosage of vitamin E, zinc sulfate monohydrate and manganese sulfate monohydrate during the feed addition process increased to some extent, and the selenium content increased to a certain extent. ...

Abstract

The invention discloses a method for raising cows capable of producing selenium-rich milk and belongs to the technical field of cow raising. The raising method comprises the following steps: each cow in a lactation period is fed with selenium yeast in the adding amount of 20-30 mg / day, the content of vitamin E, zinc sulfate monohydrate and manganese sulfate monohydrate in feed is changed 40 days after feeding starts, and then the cows are fed with the feed with changed composition until the lactation period ends. With adoption of the method, the content of selenium in the milk produced by the cows can keep higher level for a long time, the feeding cost is low, and the method is applicable to production of the selenium-rich milk.

Description

technical field [0001] The invention relates to a dairy cow breeding method for producing selenium-enriched milk, and belongs to the technical field of dairy cow breeding. Background technique [0002] Selenium is a multifunctional life nutrient that can scavenge free radicals, resist oxidation, strongly inhibit the production of peroxidative properties, enhance immune function (20 times to 30 times), protect biological cell membranes, enhance prostate regulation, and prevent blood clots , Clear cholesterol, has the same effect as insulin, can significantly promote the ability of cells to absorb sugar, blood circulation, prevent skin aging, reduce the inductiveness of carcinogens, eliminate mutated cancer cells in the body, prevent the division and growth of cancer cells, etc. . With the development of science, selenium is more and more recognized by human beings and is known as "the miraculous element of life", "the seed of life", "the fifth element of life", "the god of v...
