Application of Lactic Acid Bacteria in Animal Husbandry

1. Make high-quality silage

The production of silage depends on the fermentation of lactic acid bacteria. As a kind of anaerobic bacteria, lactic acid bacteria depend on the sugar in the plant to survive, and the two are interdependent. The application of lactic acid bacteria in animal husbandry is generally to inoculate the same type of lactic acid bacteria, so that the pH value in the silage is appropriately reduced, the lactic acid content is increased, and the quality of the silage is improved. During the silage process, lactic acid bacteria convert the sugar in the plant into lactic acid through continuous growth and reproduction, and the growth of a large number of lactic acid bacteria inhibits the reproduction of other bacteria, maintaining the integrity and safety of plant nutrients. Moreover, the fermentation of lactic acid bacteria by grass plants can also increase the appetite of livestock. At the same time, the silage made by fermentation of lactic acid bacteria can also provide high-quality forage for livestock with good taste and high nutrients in the withered seasons such as winter, and is warmly welcomed by various livestock and breeding livestock industries.

2. Improve the performance of livestock production
In the production process of poultry and livestock, the use of lactic acid bacteria can improve its production performance. For example, adding lactic acid bacteria at a concentration of 0.50%, 0.10%, and 0.05% respectively, it can be found that the use of lactic acid bacteria can significantly increase the survival rate of chicks; preventing the occurrence of piglet diarrhea is the key to raising pigs. When diarrhea occurs, lactic acid bacteria can convert lactose into lactic acid, thus lowering the intestinal pH value and inhibiting the growth of E. coli. Studies have confirmed that lactic acid bacteria preparations can significantly improve the production performance of weaned piglets.

The application of lactic acid bacteria instead of antibiotics in aquaculture is mainly reflected in water quality improvement, disease treatment and immunity to aquatic animals. Part of the lactic acid bacteria fed in the form of feed can be colonized in the intestines, and most of them are excreted into the water through feces, thereby increasing the number of lactic acid bacteria in the water body and becoming the dominant bacteria. In this way, not only can the Vibrio in the intestines and water bodies be significantly inhibited through competitive inhibition, but also through direct chemical action and indirect promotion of the denitrification of microorganisms to eliminate nitrite in the water body, which has the effect of purifying water quality.
Lactic acid bacteria micro-ecological preparations provide a high-efficiency, harmless and pollution-free new choice for feed, animal husbandry and aquaculture. As more and more new strains and specific strains are used in production, we must fully consider the characteristics of the animal flora and the relationship between parasites and the environment, and use it scientifically and rationally to achieve the greatest ecological effect and Economic benefits.
