Example Embodiment
[0006] The specific implementation of the product of the present invention is:
[0007] 1. Screening of strains: select good strains, the types of strains include lactic acid bacteria, Lactobacillus acidophilus, Lactobacillus plantarum, Bacillus subtilis, Streptococcus faecalis, Streptococcus faecium, Lactobacillus casei, Pediococcus lactis, and Bifidobacterium , Bacillus natto, yeast, photosynthetic bacteria, Rhodopseudomonas palustris, and Bacillus licheniformis.
[0008] 2. Configuration medium: According to different types of bacteria, configure different medium components. The main components of the medium are glucose, brown sugar, lactose, inorganic salt, starch, beef extract, yeast powder, yeast extract, peptone, agar, Water, citric acid, lactic acid, acetic acid, sodium hydroxide, potassium hydroxide, phosphate buffer salt. The culture medium contains coordination and growth-promoting factors. The main ingredients are vitamins, bases, porphyrins and their derivatives, ster...
Example Embodiment
[0014] Example 1: Commercially available freeze-dried photosynthetic bacteria strains 10g; yeast extract 15g, sodium acetate 17.5g, sodium chloride 10g, magnesium sulfate 5g, dipotassium hydrogen sulfate 5g, citric acid 10g, separately packaged. Mix them during use, add 10,000ml of water and place them in the sun for about 7 days (about 35°C) to obtain a microbial preparation containing about 2 billion live bacteria per ml. The bacterial agent has very good effects on enhancing the health status and growth promotion of farmed animals, especially aquatic animals, and can improve water quality.
[0015] The application effect of the product in the broiler farm:
[0016] 1. The average weight of broilers in the test group (20 days old) was 750 grams per chicken, and the average weight of the control group was 670 grams per chicken;
[0017] 2. In this period (20 days) the total feed intake of the experimental group (1100 animals) was 100kg, and the control group (1100 animals) was 80kg...
Example Embodiment
[0019] Example 2: 5g of commercially available freeze-dried lactic acid bacteria; 990g of brown sugar and 10g of yeast powder, packaged separately. Mix them during use, add 9000ml of water, and place them at room temperature for about 2 days (about 20-25°C) to obtain a microbial preparation containing 1.5-2 billion live bacteria per ml. The preparation has very good effects on the prevention of diarrhea in breeding animals, growth promotion and the like.
