Probiotics Applied Technology at Home and Abroad
In foreign countries, direct feeding microorganisms have been gradually applied to animal husbandry production. In-depth and meticulous research has been conducted in theory and application, and fruitful results have been achieved. In addition to the United States, Japan and other countries, Germany, France, Britain, the Netherlands, Denmark, Spain and other countries of the pig, beef cattle, chicken, rabbit feed, as well as yak substitute milk has also been commonly used. For example, the bacteria used in Japan's probiotic products are: Bacillus subtilis, Bacillus coagulans, Toyoi bacteria, Acid bacteria, Lactobacillus, Lactobacillus. The research of foreign prebiotics is mostly carried out by the genus Lactobacillus, Bacillus subtilis, and some streptococci. In our country, Bacillus and Lactobacillus are the main products. Most products are single fungi. China's research on forage microbes began in the 1980s. Many research units, manufacturers, and feed companies are currently conducting research and product development in this area. Some products have entered the market, but most of them are in experimental research. . Prof. He Mingqing from Sichuan Agricultural University presided over the topic of collaborative research among more than 100 experts and scholars from eight units in China, and the national “8th Five-Year Plan†research project on “research on feed additive for microorganisms†under the auspices of Shandong University in theory and technology. Breakthroughs have been made in applications and applications, and have passed the appraisal of relevant state agencies. Tests have shown that a compound probiotic powder developed using four strains of Bacillus subtilis, Bacillus licheniformis, and Cladosporium catarrhalis can be used instead of antibiotics in feed. It is estimated that by the year 2000, China will demand about 30,000 tons of probiotics each year, the market is extremely broad, and the prospects are very bright.
