Soluble microbial additive capable of improving immunity of laying hens and preparation method thereof

Abstract

The invention discloses a soluble microbial additive capable of improving immunity of laying hens. The soluble microbial additive comprises a compound microbial agent, vitamin C, phytase and a compound enzyme preparation, wherein the compound microbial agent is a mixed culture solution of bacillus coagulans and bacillus subtilis. After the microbial additive is directly fed to the laying hens, the microbial additive can achieve beneficial influence on the laying hens by improving the intestinal microbial balance and can replace antibiotics to maintain the intestinal health; meanwhile, when the microbial additive is applied to the laying hens after the laying hens with serious infection are treated by antibiotics, the intestinal flora damaged by the antibiotics can be restored.

Description

technical field [0001] The invention relates to a microbial additive, in particular to a soluble microbial additive for improving the immunity of laying hens and a preparation method thereof. Background technique [0002] The development of China's laying hen industry began in the late 1970s. According to statistics from the Food and Agriculture Organization of the United Nations (FAO), China's egg production reached 4.278 million tons in 1985, surpassing the United States to become the world's number one. The following 10 years continued to grow rapidly. As of 1996, China's egg production exceeded 15 million tons, accounting for about 35% of the world's total egg production. After the mid-1990s, China's egg production entered a stage of steady growth. At present, China's egg production has reached about 24.5 million tons, which is about 4.5 times that of the United States and about 7 times that of India, accounting for about 40% of the world's total egg production.

[0011] Raising chickens is raising intestines. Now more and more farmers are paying attention to the intestinal health of chicken flocks. In recent years, there have been more intestinal diseases in laying hens, which has brought great losses to chickens. Once a chicken develops intestinal disease, the feed conversion rate is reduced, the chickens have feed stools, the egg production rate is reduced, and thin, preserved eggs, sand-preserved eggs, etc. have been used. Many drugs have no effect, and the symptoms of medication are often relieved, and the phenomenon of recurrence after drug withdrawal
