Problems solved by technology

Fish oil and linseed (oil) have disadvantages as DHA raw materials: fish oil is rich in DHA, but it is easy to oxidize and has a special fishy smell, which affects the flavor of livestock and poultry products; while linseed (oil) is mainly rich in ALA , but the efficiency of transforming and depositing DHA in eggs is low, and a high dose is required in the diet
[0004] In the prior art of above-mentioned (1) (2) (3), raw material composition is comparatively complicated, is difficult to obtain, and process is complicated, relatively high cost, and DHA enrichment time is relatively long (could collect eggs after 15 days) ), the enrichment amount is relatively low; at present, it is also found that long-term use of split pots or other components rich in polyunsaturated fatty acids will cause some negative effects on the breeding of laying hens, for example, with the extension of feeding time, egg production The rate of DHA decreased, and the enrichment content of DHA decreased by 20-30%, which is not conducive to the stable production and supply of DHA eggs; and there are also cases that long-term feeding of polyunsaturated fatty acids will affect egg quality. Decreased egg quality is not conducive to egg preservation

preparation example Construction

[0021] In the embodiment of the present invention, the preparation method of Schizochytrium powder is as follows: fermenting Schizochytrium to obtain a fermentation liquid containing DHA oil, the fermentation liquid is centrifuged to obtain wet cells, and the temperature of the inlet air is 200 degrees and the temperature of the outlet air is 80 degrees. Spray drying was performed to obtain Schizochytrium powder containing DHA.

[0022] In the embodiment of the present invention, the preparation method of B. trispora powder is as follows: fermenting B. trispora to obtain a fermentation liquid containing β-carotene, filtering the fermentation liquid with a plate frame to obtain wet cells, and boiling the wet cells Drying to obtain dry cells of B. trispora, and then the dry cells are treated with a dry wall breaker for 25 minutes, and then pulverized and granulated, so that 99% of the particles pass through a 120-mesh sieve, and the β-carotene content is 4%. about B. trispora po...

Embodiment 1

[0024] The embodiment of the present invention provides a composite microbial feed, which is composed of 98.98 wt % daily feed for laying hens, 1 wt % Schizochytrium powder and 0.02 wt % B. trispora powder.

[0025] Wherein, in this embodiment, the DHA content in the Schizochytrium powder is 18wt% (accounting for the total amount of the Schizochytrium powder, the same below, and will not be repeated in other embodiments), the crude fat is 40wt%, and the Schizochytrium protein is 40wt%. is 8wt%, crude polysaccharide is 10wt%, and the rest is ash and moisture.

[0026] The content of beta-carotene in the B. trispora powder is 4wt% (accounting for the total amount of the B. trispora powder, the same below, and will not be repeated one by one in other embodiments), the crude fat is 35wt%, and the three-spore cloth 20 wt % of Puller's body protein, 15 wt % of crude polysaccharide, and the rest are ash and moisture.

Embodiment 2

[0028] The embodiment of the present invention provides a composite microbial feed, which is composed of 96.98wt% daily feed for laying hens, 3wt% Schizochytrium powder and 0.02wt% B. trispora powder.

[0029] In this example, the DHA content in the Schizochytrium powder is 10wt%, the crude fat is 30wt%, the Schizochytrium protein is 20wt%, the crude polysaccharide is 12wt%, and the rest is ash and moisture.

[0030] The content of β-carotene in B. trispora powder is 5wt%, crude fat is 30wt%, B. trispora body protein is 25wt%, crude polysaccharide is 25wt%, and the rest is ash and moisture.

Abstract

The invention provides a composite microbial feed for efficiently producing DHA eggs. The compound microbial feed provided by the present invention includes a ration and a compound microbial feed additive. The compound microbial feed additive includes Schizochytrium powder and B. trispora powder. The composite microbial feed provided by the invention can obtain eggs with high efficiency enrichment of DHA, without affecting the production performance of egg-laying birds, and can also improve egg quality.

Description

technical field [0001] The invention relates to the field of protein feed, and more particularly, to a compound microbial feed for efficiently producing DHA eggs. Background technique [0002] DHA (Docosahexaenoic acid) is an omega-3 long-chain polyunsaturated fatty acid, which has the effect of strengthening the brain, improving intelligence and improving vision for the growth and development of infants and children, and maintaining cardiovascular and cerebrovascular diseases for adults. health effect. DHA is also an essential fatty acid for people of all ages, and depends on external food or dietary supplement intake. By adding DHA-rich raw materials to the poultry feed, DHA in eggs can be enriched, providing people with a way to increase the daily intake of DHA. Taking eggs as an example, a large number of studies on DHA-enriched eggs have been carried out at home and abroad. The research mainly uses fish oil, flaxseed (oil), seaweed, etc. to be directly added to the fe...
