Application of microecological probiotic preparations to breeding technology and good prospects

Microecological preparations, also known as probiotics, probiotics, live bacteria preparations, and probiotics, are beneficial microorganisms isolated and identified from animals or nature or artificially formed through microbial technology engineering. They are produced by special processes such as culture, fermentation, drying, and processing. It is a biological preparation containing live bacteria and used in animals or a live bacterial probiotic preparation. In a broad sense, animal microecological preparations include not only members of normal microorganisms, that is, probiotics, but also preparations that can promote the growth and reproduction of normal microorganisms, such as prebiotics such as oligosaccharides. In a narrow sense, probiotics refer to probiotics.

Selecting appropriate probiotic feed additives according to the specific characteristics of animal husbandry can promote the growth of animals, increase body weight, improve the quality of livestock products, and increase feed utilization. At present, probiotics are added to animal husbandry feed and have been widely used in animal husbandry production. The application in pig raising is mainly to improve the body's anti-stress ability by maintaining the dominant role of probiotics in the digestive tract, limiting the toxic effects of harmful bacteria, and increasing the daily weight gain and feed conversion rate of pigs. In the poultry industry, due to the weak stress of poultry, the unfavorable breeding environment often destroys the microecological balance of the digestive tract, reduces production performance, and weakens disease resistance. Probiotic feed additives can just solve these problems. A large number of experiments have proved that probiotic feed additives can significantly increase the daily weight gain of poultry, enhance its resistance, and improve product quality. The aquatic environment is very important to the growth of aquatic animals, and the microbial technology flora in the probiotic feed additive can degrade various organic wastes in the human breeding pond, eliminate toxic factors, stabilize the pH value, create a good aquatic environment, and achieve prevention The effect of disease and healthy breeding.

   
The probiotic feed additive contains effective microbial technology flora, compound probiotic feed additive, composed of photosynthetic bacteria, lactic acid bacteria, yeast and actinomycetes and other 10 genera and 80 kinds of microorganisms. Probiotic feed additives are now widely used in more than 60 countries including the United States, Brazil, and Japan, and have achieved huge economic benefits. The main ways and methods of probiotic feed additives used in animal husbandry are:

Using the principles of microbial technology engineering, select the medium material suitable for different livestock and poultry needs to make microbial feed additives; according to the different types of livestock and poultry, growth period, etc., use probiotics to directly feed or add to the feed; these ways and methods The comprehensive application of the probiotic feed additives is the key to increase production, deodorize and improve meat quality. Probiotic feed additives can be widely used in pigs, cattle, rabbits, dogs, chickens, ducks, geese, pigeons, fish, turtles, shrimps and almost all animal husbandry and breeding.

The probiotic feed additive is a good immune activator, which stimulates the host's immune cells through the bacteria itself or cell wall components to activate them and promote the vitality of phagocytes. In addition, it can also enhance the ability of host B cells to produce antibodies. After feeding the chicks with Bacillus preparations, it was found that the central immune organs of the experimental group developed faster than the control group, the lymphocyte density in the thymus increased, the number of T cells increased, the number of bursa mucosa folds increased, and the number of T cells in the blood was also higher. . Now probiotic feed additives are used to enhance the resistance and immunity of livestock and poultry, and the effect is obvious. Moreover, a large number of experiments have shown that adding probiotic feed additives to calf diets can reduce the incidence and mortality of cattle diarrhea, and reduce the disease.
