Embodiment Construction

[0013] Lysozyme is an enzyme that can dissolve bacterial cell walls and is a general term for a class of substances. As an important member of non-specific immunity, lysozyme plays an important role in defending against the invasion of foreign microorganisms, and its content is relatively high in immune cells and macrophages of animals. Lysozyme has a good decomposing effect on Gram-positive bacteria, aerobic spore-forming bacteria, Bacillus subtilis, and Micrococcus radioduran, and it also has a good decomposing effect on Gram-negative bacteria such as Escherichia coli, Vulgaris vulgaris and Vibrio parahemorrhagicus. Dissolution. It has the bactericidal and growth-promoting effects of antibiotics, and is the first choice for replacing antibiotics in feed.

[0014] The requirement of the lysozyme used in this patent is: through drug susceptibility test, there should be obvious bacteriostatic zone at 100ppm, namely the diameter of bacteriostatic zone > 10mm. The drug suscepti...

Abstract

The invention discloses an application method for replacing antibiotics with microbic muramidase in feed. The excellent effect can be obtained by controlling the volume of addition at 60 to 400g / ton feed; and the volume of addition in the feed of different animals is relatively adjusted. By using the method, the inflammation and the infection can be resisted effectively by using the excellent effects of antibiosis and sterilization of the muramidase, the effects of antibiosis and sterilization also have the strong killing effect on bacterial strains generate drug resistance on antibiotics, and the effects of antibiosis and sterilization can ensure that the health of intestinal canals of the animals, prevent and cure the diarrhea of the animals and improve the production performance of the animals. The application method has the advantages of good curative effect, high safety, low cost, no drug resistance, no drug residue and no toxic or side effect, and the microbic muramidase is a green environment-friendly active substance.

Description

technical field [0001] The invention relates to the animal husbandry industry, in particular to an application method for replacing antibiotics with microbial lysozyme in feed. Background technique [0002] In the 1950s, zoologists discovered that adding low-dose antibiotics to feed could significantly promote the growth of livestock and poultry, and then it was widely used in feed. According to statistics, there are more than 20 kinds of antibiotics and more than ten kinds of synthetic antibacterial drugs used in feed in the world. Feed antibiotics play a positive role in preventing animal diseases, promoting animal growth, and increasing feed remuneration. However, with the development of time, the increase of bacterial resistance and drug residues in animal products have posed a serious threat to human health. The negative effects caused by antibiotics in feed have become the focus of people's perfusion. Green, pollution-free, and effective alternatives to antibiotics a...
