The microbial silage additive in this technology belongs to the National 948 introduction project (Project No. 982080). The technical core is produced using specific lactic acid bacteria fermentation technology. The test results show that compared with the control group, the whole plant corn is treated with microbial silage additives. Tons of corn silage can increase the weight of beef cattle by more than 6kg, and cows produce more than 30kg of milk. The effect is remarkable. At present, there is no similar product supply market in China. 1. Technical Principles Microbial silage, also known as silage inoculant, is a kind of microbiological additive specially used for feed silage. It consists of more than two kinds of lactic acid bacteria, propionic acid bacteria, complex enzymes, and bacterial growth promoters. The purpose is to regulate the microflora in silage, regulate the silage fermentation process, promote lactic acid bacteria to produce lactic acid more quickly, and promote the conversion of polysaccharides and crude fiber, thereby effectively improving the quality of silage. 2. Technical advantages (1) The microbial silage is added to the silage, in which the lactic acid bacteria rapidly dominate the fermentation, accelerating the fermentation process, producing more lactic acid, rapidly decreasing the pH, limiting the activity of plant enzymes, and inhibiting the degradation of crude protein into non-protein Nitrogen helps reduce protein loss. (2) Increased the recovery rate of fermented pits by 1% to 2%, which improved the digestibility of silage. (3) Reduced the amount of acetic acid and ethanol in silage, increased the content of lactic acid, improved palatability, and increased food intake. (4) It can protect the silage protein from being decomposed and is directly used by the rumen. 3, usage and consumption usage: This product can be directly added in the silage, when used first dissolved in water, shake; sprinkled in the silage can be. Dosage: Add 10g per ton of silage. 4. Analysis of Economic Benefits The use of advanced microbial silage additive technology to improve the silage mode of green maize, improve the quality of silage corn, improve the success rate of silage, each cow can increase milk production 300 ~ 500 kg; development of silage silage The new technology will study new microbial additives for alfalfa silage, increase the success rate of alfalfa silage, improve the quality of silage, raise the production level of cattle and sheep, and increase the production efficiency of the entire animal husbandry. Each cow will increase the benefit by 300 yuan. The efficiency of a sheep is increased by 10 yuan and the economic benefits are inestimable.
