Problems solved by technology

[0003] However, the key component in Schizochytrium powder, the polyunsaturated fatty acid DHA, is unstable due to its molecular formula containing six double bonds, and is easily oxidized, which makes Schizochytrium powder lose its due effect in breeding, and what's more. The oxidized DHA forms a chain reaction of oxygen free radicals in animals, which damages the biofilm and its functions, resulting in the formation of cell hyaline lesions and fibrosis, and large-scale cell damage causes damage to nerves, tissues, organs, etc.

Embodiment 1

[0018] Schizochytrium Algae Powder 1.6Kg

[0019] Phaffia red yeast powder 0.4 Kg

[0020] Ordinary livestock feed 98 Kg

[0021] In this feed, the net content of DHA is 2.88g / kg; the net content of astaxanthin is 0.012g / kg.

[0022] Thoroughly stir and mix the above-mentioned feed with a mixer, grind it to 8-25 μm, and feed it to milk-producing animals such as cows and goats to obtain milk products rich in DHA. The DHA content in every 100ml of medium milk can reach 6-15mg, which is 10-20 times that of ordinary milk. At the same time, it retains the complete triglyceride structure of DHA and is easier to be absorbed by the human body.

[0023] The DHA milk product prepared by the present invention is rich in DHA and does not contain EPA and other ingredients, and by adding Phaffia rhodozyme containing natural antioxidant astaxanthin, the DHA in the produced milk product has good antioxidant properties It can effectively prevent the oxidative deterioration of the product ca...

Embodiment 2

[0027] Schizochytrium Algae Powder 1.75 Kg

[0028] Phaffia red yeast powder 0.25Kg

[0029] Ordinary poultry feed 98 Kg

[0030] In this feed, the net content of DHA is: 3.15g / kg; the net content of astaxanthin is: 0.0075g / kg.

[0031] Fully mix the above feed with a mixer and grind it to 8-25 μm, feed it to chickens, ducks, geese, quail and other egg-laying poultry to obtain nutritious and healthy eggs rich in DHA and astaxanthin. Each egg produced can be rich in Set DHA content as high as 80mg or more. Adding the nutritional enhancer of astaxanthin deepens the color of the egg yolk, protects the enriched DHA from oxidation, and can effectively prevent the product from oxidative deterioration caused by oxygen, light, etc., and its antioxidant stability is more than 50 times higher than that of free DHA. The long-term storage of the product has richer nutritional components and no fishy smell, which can meet the special needs of pregnant women, infants and teenagers for DH...

Embodiment 3

[0034] Schizochytrium Algae Powder 1.86Kg

[0035] Phaffia red yeast powder 0.14Kg

[0036] Ordinary aquatic bait 98 Kg

[0037] In this feed, the net content of DHA is: 3.348g / kg; the net content of astaxanthin is: 0.0042g / kg.

[0038] The above-mentioned feed is fully stirred and mixed with a mixer, and then pulverized to 8-25 μm, and then fed to aquatic animals. In the experiment of Penaeus monodon, after a 35-day breeding test, the gonad development rate of female Penaeus monodon in the experimental group was 55.8±3.7%, the maturity rate was 48.3±4.2%, the total number of eggs laid was 22.723 million, and the total number of spawned shrimp was 101 times , with an average of 225,000 eggs per fish, a total of 14.336 million nauplii, and an average hatching rate of 63.1±4.6%; the maturity rate of male shrimp was 72.5±5.1%. In the control group, the gonad development rate of female Penaeus monodon was 18.6±2.4%, the maturity rate was 10.0±2.5%, the total number of eggs laid...

Abstract

The invention discloses a nutrition enhancer compounding schizochytrium aggregatum powder and phaffia rhodozyma powder which is prepared by mixing 80-99.5 percent of schizochytrium aggregatum powder and 0.5-20 percent of phaffia rhodozyma powder. The nutrition enhancer is efficient and safe, when being applied on seedling cultivation, the nutrition enhancer can improve survival rate, immunity, premunition and stress resistance capability of spouts; when being applied on aquaculture, the nutrition enhancer can improve sexual maturity of parent strain, and increase egging laying amount, quality of eggs and hatching rate; when being used as feed additive of eggs, the nutrition enhancer can enrich the DHA and astaxanthin in yolk, reduce the cholesterol content and increase nutrition values of eggs; when being used as feed additive of dairy cow and milch goats, the nutrition enhancer can enrich DHA in milk to produce dairy products with high and stable DHA content; and when being used as the feed additives, the nutrition enhancer can improve the meat quality and mouthfeeling of cultivated varieties, increase the brightness of body color of the cultivated varieties, is not easy to be oxidized, wide in range of application and more obvious in effect.

Description

technical field [0001] The invention relates to a nutritional enhancer compounded with Schizochytrium powder and Phaffia rhodozyma powder and its application in breeding. Background technique [0002] In various farming applications, Schizochytrium plays an irreplaceable role, which is mainly determined by the most critical component DHA in Schizochytrium. DHA, docosahexaenoic acid, is not only a very important polyunsaturated fatty acid for the human body, but also plays an inestimable role in farming. In seedling cultivation, it can improve the survival rate, immunity, disease resistance and stress resistance of larvae. In 2000, Davis et al. used Schizochytrium dry powder as a bait additive to feed oyster larvae. As a result, the growth rate was higher than that without this additive. The increase of 3.2%, the effect of increasing production is obvious. This is mainly because using Schizochytrium dry powder as a bait additive can meet the requirement of polyunsaturated f...
