Embodiment 1

[0012] The preparation of embodiment 1 Hericium erinaceus fermented extract

[0013] (1) Slant culture:

[0014] Quickly inoculate the pure strain of Hericium erinaceus into the special slant medium in the ultra-clean bench of the sterile room, and cultivate it at 26-28°C for 7-9 days to obtain the strain of the liquid shake flask; the formula of the special slant medium is: Potato 100: Glucose 1: Potassium dihydrogen phosphate 1: Agar 1, pH natural;

[0015] Preparation method: Peel 200 g of fresh potatoes and cut into small pieces, add 1000 ml of water and boil for 25 minutes, filter with gauze to get the filtrate, soak the agar in advance, add to the filtrate and boil while stirring continuously until it is completely dissolved, then add glucose and phosphoric acid respectively Potassium dihydrogen and other substances are stirred evenly, dispensed into test tubes while they are hot, corked and placed in a sterilizer for sterilization, steam pressure is 1.1 atmospheres, ...

Embodiment 3

[0039] Example 3 Fermented extract of Hericium erinaceus to promote growth of broiler chickens

[0040] 1. Materials and methods

[0041] 1.1 Experimental animals and grouping

[0042] Select 3,000 1-day-old Arbor Acres (AA) broilers, with a male-female ratio of half and half, and body weight (36.25±0.38). After observing no abnormality for 6 hours, they were randomly divided into 2 groups, with 3 repetitions in each group, and 500 rats in each repetition.

[0043] 1.2 Diet composition and nutrition of experimental animals

[0044] The test feed materials corn, soybean meal and calcium hydrogen phosphate meet the requirements of the national health standard (GB / 13078-2001). The diet was designed with reference to the national broiler feeding standard (NY / T33-1986) and NRC (1994) poultry feeding standard, and the fermented extract of Hericium erinaceus was added to the basic diet (daily No drug additives are added to the grain) and stir well.

Embodiment 4

[0051] Example 4 Effect of Hericium erinaceus fermented extract on immune function of broiler chickens

[0052] 1. Materials

[0053] The broilers used in the experiment were AA commercial broilers aged 14, 21 and 28 days. The broiler chicken group fed with the fermented extract of Hericium erinaceus was taken as the test group, and the addition amount was 0.3%; the broiler group fed without the fermented extract of Hericium erinaceus in the diet was the blank control group. 10 male and 10 hens were randomly selected from each group, slaughtered and peeled by bloodletting, their thymus, spleen and bursa of Fabricius were weighed respectively, and the immune organ index was calculated.

[0054] Immune organ index = immune organ mass / body weight × 100

[0055] 2. Data processing and analysis

[0056] The experimental data were statistically analyzed using SPSS 19.0 statistical software.

[0057] 3. Results and Analysis

Abstract

The invention discloses a hericium caput-medusae fermentation extract feed additive which is an extract obtained by performing inoculation, shake-flask culture and seeding tank fermentation on hericium caput-medusae strains and performing steaming and filtration on fermenting liquid under the temperature of 95-100 DEG C and concentrating filtrate; 0.05-0.75 percent of a hericium caput-medusae fermentation extract is added into a feed, so that the daily gain of meat chicken can be increased, and growth of animals is obviously promoted; the daily gain is increased by 8.96 percent; the feed conversion rate is increased, and the productivity of the animals is improved; meanwhile, the quality of poultry meat can be also improved, and the cholesterol content of chicken meat is reduced; the contents of cholesterols in breast muscles, leg muscles and livers of the meat chickens are respectively reduced by 30.67 percent, 48.18 percent and 57.04 percent.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed additive for Hericium erinaceus fermented extract and feed for producing low-cholesterol livestock and poultry products. Background technique [0002] Antibacterial and antiviral have always been a major problem in the breeding industry, and the problem of residues of antibiotics has attracted great attention from all over the world. Since January 1, 2006, EU countries have banned the use of antibiotic growth-promoting feed additives for food animals. So it is very urgent to find a green, efficient and safe feed additive. In recent years, the application of beneficial microorganisms to the development and production of feed additives has provided a new development path for feed additives, and provided a healthy, non-toxic and non-polluting choice for the food industry, feed industry and livestock and poultry breeding. [0003] Hericium erinaceus[ Hericium caput-medusae (B...
