Abstract

The invention is applicable to the technical field of microbial breeding and provides lactobacillus plantarum. The lactobacillus plantarum is lactobacillus plantarum PLBS003, is collected in China General Microbiological Culture Collection Center of China Committee for Culture Collection of Microorganisms on December 17, 2018 and has an accession number of CGMCC No. 16943. The invention further provides application of the lactobacillus plantarum in feedstuff of Laoshan dairy goats. Thereby, the lactobacillus plantarum PLBS003 provided by the invention has relatively good thermal stability andacidic stability; and by adding an appropriate level of lactobacillus plantarum PLBS003 into rations of the Laoshan dairy goats, the digestive absorption function of the Laoshan dairy goats to nutrients in the feedstuff can be strengthened, the milk performance of the Laoshan dairy goats and nutrients in milk composition can be improved, and the economic benefit of the Laoshan dairy goats can be improved.

Description

technical field [0001] The invention relates to the technical field of microbial breeding, in particular to a plant lactobacillus and its application in Laoshan dairy goat feed. Background technique [0002] Since the 1980s, the Ministry of Agriculture of my country has actively encouraged and supported the dairy goat industry, making dairy goat breeding in my country's agricultural and pastoral areas show a momentum of great development, solving the plight of shortage of food resources and increasing demand for livestock products in my country, and providing a new environment for animal husbandry. It has laid the foundation for the stable development of the industry. However, there are many problems in the dairy goat production industry in my country. In order to pursue the production performance of dairy goats and increase economic benefits, breeding companies choose to add antibiotics and other additives to the feed of dairy goats to improve the utilization rate of feed fo...
