I. Production: The resurrection of bacteria and the preparation of broth are the important 51 items in the entire production. In order to increase the rejuvenation rate of the strains, a few (about 2 grams) of white sugar (5455, 21.00, 0.39%) should be added to 200 ml of water before the strains are revived. Then live dry bacteria should be added, and then allowed to stand at room temperature for 1-2 hours. Hours, mix well with pre-made 1% salt solution. The prepared broth should be used up the same day to prevent failure. At the same time pay attention to the amount of bacteria used.
When stalks enter the pit, the sprayed broth must be uniform, and the storage should be fully compacted to drain the air, and the anaerobic conditions should be created for the propagation of the fermentation bacterium. The moisture in the storage must be controlled at about 60%-70%. Take a sample of straw and twist it with both hands. If there is no water drop, after loosening the hand, you can see that the water is obvious, loose and the water content is the most suitable. When wheat straw and rice straw are used for micro-storage, 1 pound of corn (2460, 5.00, 0.20%) flour or bran should be sprinkled on each layer to provide certain nutrients for the propagation of the initial bacterial species in order to increase the microbiological storage. the quality of.
After the straw is layered and compacted until it is 30-40 cm higher than the cellar, the plastic (10665, 230.00, 2.20%) film is pressed by hand from the four sides to the seal, and the air is exhausted. The seal must be tightly sealed to prevent leakage. Gas, then covered with grass. Make it 40 cm above the ground and dig a drainage ditch around it to prevent rain water from seeping. To ensure that the upper part of the microbiological beverage does not become rotten and spoiled, 250 grams of salt powder may be sprinkled on the uppermost layer before the film is sealed.
Second, feeding: generally after 20-30 days of fermentation, can be used to feed. The quality of the product can be judged by the appearance, smell and feel of the external features. High-quality micro-storage color is olive green (green straw) or golden yellow (dry straw), straw soft and loose, and has acid and aroma.
When taking the material, start from a corner and take it from top to bottom, and take the material outlet as far as possible in the backside to avoid 2 fermentations of the stored material. Each time it is taken out, it should be fed on the same day. Immediately afterwards, seal the mouth with plastic film to prevent rainwater intrusion and cause deterioration of micro-feeds. When feeding micro-feeds each time, the tank is required to be clean and the feeding amount is from low to high, so that the livestock have an adaptation process.
When feeding, it should also be matched with some energy feeds and protein concentrates or high protein forages to meet the normal growth of livestock. For micro-feeds, salt is added at the time of manufacture. This portion of salt should be deducted from the large-scale food combination.
