Agent of lactic acid bacteria for relieving dysentery and preparation method thereof

Abstract

The invention provides an agent of lactic acid bacteria for relieving dysentery and a preparation method thereof, which relates to a feed additive for preventing and curing livestock diseases and a preparation method thereof. The invention solves the problems that in the existing method for preventing and curing livestock diseases, antibiotics and chemicals are added into livestock feed, so that the livestock have drug resistance, the animal normal flora is disordered, the immune function of the organism is inhibited, and the antibiotics and the chemicals remain in animal bodies. The product is prepared from Lactobacillus acidophilus fermenting agent, whey powder, defatted soybean protein powder and water. The method comprises the following steps: (1) preparing the Lactobacillus acidophilus fermenting agent by using Lactobacillus acidophilus strains and an MRS culture medium; (2) adding the whey powder and the defatted soybean protein powder into hot water to obtain a Lactobacillus acidophilus culture solution; and (3) adding the Lactobacillus acidophilus fermenting agent into the culture solution for fermenting, and then, carrying out spray drying to obtain the agent of lactic acid bacteria for relieving the dysentery. Antibiotics or chemicals are not added into the product, thus the product does not have toxic side effect, drug resistance and residues, is an environment-friendly functional feed additive and can be applied to animal husbandry.

Description

technical field [0001] The invention relates to a feed additive for preventing and treating diseases of livestock and poultry and a preparation method thereof. Background technique [0002] In the livestock and poultry industry, the existing method of preventing and treating livestock and poultry diseases is to add antibiotics and chemicals to the livestock and poultry feed. While promoting the development of the livestock and poultry industry, this method has also produced serious adverse consequences. First of all, the long-term use of antibiotics in livestock and poultry can cause pathogenic bacteria to mutate into drug-resistant strains and produce drug resistance. Secondly, antibiotics remain in livestock and poultry, and antibiotics left in meat, eggs, milk and other foods cannot be completely inactivated by heating. People's long-term intake of such foods containing residual antibiotics will directly affect human health. Immunity and health. Contents of the inventi...
