specific Embodiment approach
[0006] The specific embodiment of product of the present invention is:
[0007] 1. Screening of strains: Select excellent strains, including lactic acid bacteria, Lactobacillus acidophilus, Lactobacillus plantarum, Bacillus subtilis, Streptococcus faecalis, Streptococcus faecium, Lactobacillus casei, Pediococcus lactis, Bifidobacterium , Bacillus natto, yeast, photosynthetic bacteria, Rhodopseudomonas palustris, and Bacillus licheniformis.
[0008] 2. Configure the culture medium: configure the culture medium with different components according to different types of bacteria. The main components of the culture 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 Buffered Saline. The medium contains coordinating and growth-promoting factors, and its main components are vitamins, bases, porphyrin and its derivative...
Embodiment 1
[0014] Example 1: 10 g of commercially available freeze-dried photosynthetic bacterial strains; 15 g of yeast extract, 17.5 g of sodium acetate, 10 g of sodium chloride, 5 g of magnesium sulfate, 5 g of dipotassium hydrogen sulfate, and 10 g of citric acid were packaged separately. When using it, mix it, add 10,000ml of water and place it under the sun for about 7 days (about 35°C) to obtain a microbial preparation containing about 2 billion live bacteria per milliliter. The bacterial agent has a very good effect 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 broiler chickens (20 days old) in the test group 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 ...
Embodiment 2
[0019] Example 2: 5 g of commercially available freeze-dried lactic acid bacteria; 990 g of brown sugar and 10 g of yeast powder are packaged separately. When using it, mix it, add 9000ml of water and leave it at room temperature for about 2 days (about 20-25° C.), to obtain a microbial preparation containing about 1.5-2 billion viable bacteria per milliliter. The preparation has very good effects on preventing diarrhea and promoting growth of farmed animals.
