Preparation of feeding live bacterial acid, and dedicated bacterial strain

Abstract

This invention discloses a feed-use living bacterium acidic preparation and its special strain. The active component of the feed-use living bacterium acidic preparation is Bacillus subtilis subsp. Subtilis Gendone-01 (CGMCC No.1946). The feed-use living bacterium acidic preparation can be used for livestock as a substitute for antibiotics. And the livestock product does not have residual antibiotics, which is good for human health. Besides, the feed-use living bacterium acidic preparation can increase feed utility, reduce feed cost, sterilize in intestines, reduce diarrhea, and improve anti-stress ability and immunity.

Description

technical field [0001] The invention relates to a live bacterial acid preparation for feeding and a special bacterial strain thereof. Background technique [0002] With the improvement of people's living standards and the strengthening of environmental protection awareness, the requirements for the quality of animal products and the hygienic environment for animal feeding are getting higher and higher. Traditional feed antibiotic additives are gradually being banned or restricted. In January 2006, the European Union It has been formally decided to ban the addition of growth-promoting antibiotics to livestock and poultry feed. Subsequently, Japan, South Korea and other Asian developed countries also formulated corresponding policies and regulations to limit antibiotic residues in animal products. [0003] Finding alternatives to antibiotics and alleviating the negative impact of antibiotic ban on livestock and poultry production is an urgent problem to be solved by the anima...

Problems solved by technology

[0004] Acidifiers and live bacteria preparations cannot completely replace feed antibiotics

The application effect of acidifier in pigs is remarkable, especially for weaned piglets. It can make up for the deficiency of gastric acid secretion, activate protease activity, and promote the digestion and absorption of nutrients. It can be used as the first choice for antibiotic substitutes. The need is large, and it is also greatly affected by the buffering capacity of the diet. In production practice, it is impossible to add a large dose of acidulant

As a substitute, probiotics have the disadvantages that live bacterial preparations are easy to inactivate, are not resistant to the acidic environment of the stomach, and are difficult to gain a competitive advantage in the gastrointestinal flora

[0005] Due to the constraints of national conditions, the environmental conditions of animal breeding are relatively poor. At present, most of the livestock and poultry breeding in my country cannot do without antibiotics. The antibiotic residues in livestock and poultry products are relatively high and basically cannot be exported, which seriously restricts the healthy development of animal husbandry. , so the development and production of high-efficiency and safe feed additives that can replace antibiotics can not only improve the quality of livestock and poultry, but also have great significance for improving the ecological environment and realizing the sustainable and healthy development of animal husbandry
