Problems solved by technology

[0004] However, the deficiencies of the technical data cited above are that fish products are used as the source of DHA, and in the prior art, fish products are mostly added to feed as the main source of DHA to improve the performance of farmed animals
However, the DHA provided by fish products is not only low in content, but also has a heavy fishy smell, is easy to oxidize, and the extraction process is complicated and costly.
In addition, with the increasing scarcity of marine fish resources, using fish products as a source of DHA is considered an unsustainable way of development. At the same time, fish products also have potential marine pollution and other problems, so look for fish product substitutes It is imperative to provide DHA
[0005] In addition, scientific research has revealed that different types of PUFAs compete and inhibit each other in the body, especially when exogenous ω-3 PUFA is taken alone, it will reduce the proportion of ω-6 fatty acids in the body, which may affect the health of the body
[0006] In addition, due to the presence of multiple unsaturated double bonds in PUFA molecules including DHA, they are extremely susceptible to air oxidation during use, and produce harmful substances such as low-level aldehydes and ketones, which not only affects the efficacy of PUFA, but also causes animals to eat them. After being oxidized PUFA, it will also affect health

Embodiment 1～12

[0044] Prepare the microbial feed additive, and the formula is shown in Table 1.

[0045] Table 1

[0046]

[0047] After the above-mentioned components are pulverized according to the proportion, they are uniformly mixed with a mixer, passed through a 20-mesh American standard sieve, inspected, weighed, and packaged to obtain the product. The technical indicators achieved by the microbial feed additives prepared according to the formulas of Examples 1-12 are shown in Table 2.

Embodiment 13

[0051] Application of microbial feed additives in laying hen farming:

[0052] The microbial feed additive prepared in Example 5 was added to the ration of laying hens in an amount of 0.2% of the weight of the ration, mixed evenly, and fed to laying hens for four weeks to obtain eggs rich in DHA. It has been determined that the DHA content in eggs is as high as 180mg, which is about 16 times that of ordinary eggs, and the cholesterol content is 28% lower than that of ordinary eggs. The eggs are delicious, not smelly, and have no fishy smell.

Embodiment 14

[0054] Application of microbial feed additives in broiler farming:

[0055] The microbial feed additive prepared in Example 10 was added to the diet of broilers in an amount of 1.0% of the feed weight, mixed evenly, and fed to newly hatched broiler chicks. After two months, the content of DHA and AA in chicken leg meat, the growth rate of broiler chicken and the death rate because of suffering from ascites syndrome were counted. The results show that after broiler chickens are fed with the feed that has added the feed additive of the formula of embodiment 10, the mortality rate of broiler chickens has been reduced by about 9%, the growth rate has increased by about 12%, and the content of DHA and AA in chicken leg meat has increased by about 3.2 times and 1.6 times.

Abstract

The invention relates to a microbiological feed additive and a preparation method and an application thereof, relating to a feed additive. The invention provides a microbiological feed additive compounded with various microbiological fermented powders and a preparation method and an application thereof. The microbiological feed additive consists of the following compounds according to weight percentages: 60%-99% of DHA (Docosahexenoic acid) fermented powder, 0-25% of AA (Arachidonic acid) fermented powder and 1%-30% of R. spkaeroides fermented powder. After the nutrition compositions are mixed uniformly after being crashed respectively; and then sieving, checking, weighing and packing are performed. The microbiological feed additive can be used as an active in aquatic product, poultry and livestock cultivation feeds, and the addition accounts for 0.2%-5.0% of total mass of basal feed. The contents of the nutrition compositions in the feed are increased, so that the resistance against diseases, survival rate, growth rate and nutritive value of fed animals are improved; rich coenzyme Q10 and carotenoid are used as antioxidants, so that the oxygenization of polyunsaturated fatty acid can be inhibited, the stability and using effect of polyunsaturated fatty acid are improved, and the compounding effect is obvious.

Description

technical field [0001] The invention relates to a feed additive, in particular to a microbial feed additive compounded by various microbial powders and a preparation method and application thereof. Background technique [0002] Scientific research shows that polyunsaturated fatty acids (PUFA), especially long-chain polyunsaturated fatty acids that some animals cannot synthesize themselves: docosahexaenoic acid (DHA for short) and arachidonic acid (Arachidonic acid, AA for short), has the effect of promoting the growth of farmed animals and improving immunity. It is very important to add these PUFAs to the feed to maintain the normal function of the animal body. In recent years, animal products rich in PUFA are favored by consumers, for example, poultry eggs, poultry meat, and aquatic products rich in DHA, and the composition and content of PUFA in animal products depends on the content of PUFA in the diet and type, the two remain the same. Therefore, it is necessary to add...
