Embodiment 1

[0042] The preparation of embodiment 1 Schizochytrium powder

[0043] The steps for preparing Schizochytrium sp. D1.0 with the preservation number of CCTCC NO.M2016617 in China Typical Culture Collection Center are as follows, as follows: figure 1 As shown, the following steps can be repeated on the fermenter complete set of equipment:

[0044] (1) Preparation of culture medium

[0045] The seed medium is 20-50g / L glucose, 2-4g / L yeast extract, 10-20g / L sodium glutamate, 1.5-2.0g / L sodium chloride, 1.0-2.0g / L magnesium sulfate, and The amount is water, pH5.0-7.0. The prepared medium was sterilized by steam at 121°C, and after 30 minutes, it was lowered to the inoculation temperature for use;

[0046] The fermentation medium is glycerol 50-70g / L, glucose 50-70g / L, yeast extract 4-6g / L, sodium glutamate 10-20g / L, sodium chloride 2.4-4.0g / L, magnesium sulfate 1.0 -2.0g / L, ammonium sulfate 1.0-2.0g / L, the balance is water, pH5.0-7.0. The prepared medium was sterilized by stea...

Embodiment 2

[0069] Embodiment 2 Schizochytrium algae powder feeding dairy cows

[0070] (1) Selection and grouping of experimental animals

[0071] According to the principle of roughly the same or similar age, parity, lactation time and physiological state, 64 healthy Holstein lactating cows in the middle stage of lactation were selected and randomly divided into 4 groups, 16 cows in each group.

[0072] (2) Test diet

[0073] Basic ration—concentrate feed and roughage, keeping the original feeding conditions of the cattle farm: 10kg of concentrate feed, 6.5kg of brewer’s grains as roughage, 22kg of silage, 2.2kg of beet meal, and 2.2kg of Leymus chinensis every day. Feed once.

[0074] Schizochytrium powder: Schizochytrium powder was prepared according to the method in Example 1 above.

[0075] Addition method of Schizochytrium algae powder: according to the amount added in groups, add the test amount of each group to the concentrate and mix evenly.

[0076] (3) Feeding and manageme...

Abstract

The invention discloses an application of schizochytrium sp. or a preparation thereof to increment of DHA content in milk of ruminants. The animals are ruminants. The preservation No. of the schizochytrium sp. (Schizochytrium sp.) in the China Center For Type Culture Collection is CCTCC NO.M2016617. The schizochytrium sp. powder prepared from the schizochytrium sp. can increase the DHA content inthe milk of the ruminants. The made schizochytrium sp. powder reserves primary inherent components of the schizochytrium sp. The high-DHA milk which is from natural is organic, safe, stable, and easyto absorb, can be used as a safe effective way for ingesting natural DHA for people, and can cater to and meet consumer demands. Besides, the schizochytrium sp. or the preparation thereof can be usedfor making a new breakthrough opening for improving the production properties and product quality in the breeding trade of livestock, the production benefits are increased, and the schizochytrium sp.or the preparation thereof has important significance.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to the application of Schizochytrium powder in increasing the DHA content in ruminant milk. Background technique [0002] DHA (Docosahexaenoic acid, docosahexaenoic acid, 22:6, n-3) is an essential fatty acid, that is, a long-chain fatty acid that cannot be synthesized by the human body and has important physiological functions. DHA is the main component of the human brain and retina, with a content of 20% in the cerebral cortex and 50% in the retina. Therefore, it plays an important role in the development of the nervous system and visual system of the fetus and is important for maintaining normal intelligence. It also has important physiological functions such as preventing and treating cardiovascular diseases, anti-cancer, and anti-inflammation. [0003] In addition, the application of DHA in dairy products is not uncommon, and the widespread use in infant formul...
