Special lactobacillus inoculum for silage and its making method

Abstract

An inoculating lactic ferment for silage is prepared from two kinds of dried living bacteria powder, cellulase, semi-cellulase, carbohydrate, manganese sulfate and diatomite through medium-temp. pressure-reduction drying and gelatin-starch dual-coating or freeze-drying. Its advantages are great number of living bacteria 90 billions CFU / g, long storage period, and high effect (increasing milk by 283 kg).

Description

Technical field: [0001] The invention belongs to the field of feed processing, in particular to a special lactic acid bacteria inoculant for silage and a manufacturing method thereof. technical background: [0002] The dairy cattle industry in my country has developed rapidly. The output has increased by 5 times in the past 5 years. By 2000, it will reach 4.89 million heads (including adult fine breed cattle, improved cattle, young cattle and dual-purpose cattle for milk and meat production). The total milk output is 8.27 million tons. The average annual milk consumption per person is actually nearly 7 kilograms. If the average daily milk consumption per person is only 0.25 kilograms, the average annual milk consumption per person is nearly 81 kilograms. There is still room for development of more than 10 times the current basic level. It can be predicted that my country's dairy cows will develop in It will maintain a strong momentum for quite a long time, but what is not comp...

Problems solved by technology

The most widely used lactic acid bacteria abroad include Lactobacillus plantarum, Lactobacillus acidophilus, Lactobacillus xylosus, Pediococcus pentosaceus, Pediococcus acidilactici, Propionibacterium shermanii, etc. The carbon source of the main components of the fermentation medium is generally glucose, lactose, soluble starch and sucrose, and the nitrogen source is generally whey powder, yeast culture and hydrolyzed animal protein. The fermentation products of batch fermentation are generally separated by filtration, ultrafiltration or centrifugation. Concentration; the isolated high-purity bacteria are either spray-dried (high loss rate) or freeze-dried (high cost), the latter requires a corresponding freeze-drying protective agent, except that the freeze-drying equipment mainly comes from a one-time investment The protective agent is the key to reduce the loss of live bacteria freeze-drying and prolong the shelf life of the product. The protective agent is mainly composed of skimmed milk powder or maltodextrin, glycerin, calcium carbonate, sucrose, maltose, sodium glutamate, inositol, manganese sulfate, etc.; Foreign SIB products such as SIL-ALL from the UK and Sil-Early from the United States guarantee the total number of live lactic acid bacteria > 10 billion CFU / ton (silage), and the total number of live lactic acid bacteria from LAB produced by AgMaster in Canada is guaranteed to be 100,000-600,000 CFU / ton (silage alfalfa, corn, etc.), so the total number of viable lactic acid bacteria on the market is generally 100-100 million CFU / g, and the shelf life is 1 year. Generally, frozen storage is used, and the cost of the product is relatively high.
