Formula and detailed fermentation method of microbial fermented feed

Probiotics can not only process and decompose the macromolecular substances in crude protein and starch that are difficult for livestock and poultry to digest and absorb into small molecular nutrients such as glucose, amino acids and vitamins that are easy to digest and absorb, but also greatly degrade crude fiber and produce a large number of bioactive substances, so as to improve the digestion and absorption rate and nutritional value of feed. In addition, beneficial microorganisms in bio fermented feed can also kill pathogenic bacteria, maintain microecological balance in animals, enhance functional immunity, and have a certain role in disease prevention and treatment. Microbial feed I. microbial fermentation feed formula: unified bran or grass powder 55%, wheat bran 16%, corn 15%, cake 10%, molasses or red bran 2%, beneficial microbial agents 2% (including dozens of strains of five major bacterial groups, such as cellulose decomposing bacteria, bacillus, lactic acid bacteria, bifidobacteria, yeast). （1）   Biological fermentation feed process 1. Dissolution of bacteria: A. put 20 to 30 jin of warm water in the barrel (the temperature is 30 ℃); B. Add a kilogram of brown sugar and stir well; C. First add solid bacteria and stir evenly, then add liquid bacteria and stir evenly; D. Let it stand for one hour. 2. Add water to dilute the evenly stirred strain to 300 kg; 3. Mix with 700 kg feed evenly; 4. Put it into a jar or bag (film bag) for fermentation; 5. After 3 to 5 days, the smell of wine is the fermentation of mature biological fermentation. The feed contains more beneficial microbial agents such as fiber decomposing bacteria, semi fiber decomposing bacteria and microbial enzymes. During the fermentation process in the animal body, it can not only process and decompose the macromolecular substances in crude protein and starch that are difficult for livestock and poultry to digest and absorb, but also convert them into small molecular nutrients such as glucose, amino acids and vitamins that are easy to digest and absorb, Moreover, it can greatly degrade crude fiber and produce a large number of bioactive substances, so as to improve the digestion and absorption rate and nutritional value of feed. In addition, beneficial microorganisms in bio fermented feed can also kill pathogenic bacteria, maintain microecological balance in animals, enhance functional immunity, and have a certain role in disease prevention and treatment. （2）   Production method of bio fermented feed 1 Weigh the raw materials according to the above formula, sift them after crushing (1mm hole), and then stir them evenly for standby. 2. There are two kinds of beneficial microbial agents: solid and liquid. If solid beneficial microbial agents are used, they can be directly added to the above raw materials and stirred evenly; If liquid beneficial microbial agents are used, they can be dissolved in tap water without bleaching powder or deep water, and then brown sugar or molasses can be added to make uniform sugary bacterial water. 3. Spray sugar containing bacteria water or sugar water (referring to those using solid beneficial microbial agents) evenly into the fermentation material, mix and sprinkle at the same time, so that the water content of the fermentation material can reach the degree of kneading into a ball by hand and dispersing on the ground. Generally, the weight ratio of material to water is 1:0 About 4 is appropriate. 4. Put the mixed fermented feed into a plastic bucket or ceramic jar or a cement pool, slightly compact the material, and then drill holes in the fermented feed with a wooden stick with a diameter of 2-3 cm, and drill the holes to the bottom, with a hole spacing of 5-10cm. Then cover it with wood or film to let it ferment naturally. Generally, when the temperature is below 25 ℃, the fermentation time is 4-5 days, and when the temperature is above 25 ℃, it is 2-3 days. 5. After fermentation, if the pH value reaches below 4-5 and there is a strong wine flavor, the fermentation is successful& nbsp; （3） Usage of bio fermented feed (1) piglet formula feed (%) formula 1: Bio fermented feed 20, corn 52, soybean meal or soybean cake 22, fish or composite egg powder 2, pig premix 4. Formula 2: biological fermentation 15, corn 44, bran 10, soybean meal or soybean cake 24, fish meal or composite protein powder 3, pig premix 4. (2) Medium pig formula feed (%) formula 1: biological fermented material 25, corn 50, soybean meal or soybean cake 21, pig premix 4. Formula 2: biological fermentation material 30, corn 38, bran miscellaneous grains 10, soybean meal or soybean cake 24, fish meal or composite protein powder 3, pig premix 4. (3) Pig formula feed (%) formula 1: biological fermented material 30, corn 36, bran cereals 12, soybean meal or soybean cake 16, pig premix 4& nbsp; Formula 2: biological fermented material 35, corn 33, bran or cereals 12, soybean meal or soybean cake 16, pig premix 4& nbsp; 2、 Application method of biological fermentation material. It is not necessary to add any other additives and cooking to feed pigs with bio fermented feed formula. It is better to feed pigs directly after wetting with water before feeding (it is better to hold water with hands), or after wetting for several hours. When feeding, the piglets can eat more than one meal at a fixed time, and the medium and large pigs can eat freely without quantitative feeding. They can be fed 2-3 times a day. Each time, the feeding amount should be finished within 30 minutes, and there is no material left in the trough (80% full).
