Method for reducing macrolide drug resistance gene abundance in livestock and poultry excrement

Abstract

The invention discloses a method for reducing macrolide drug resistance gene abundance in livestock and poultry excrement. The method comprises the following steps: S1, uniformly mixing fresh livestock excrement and straw fragments and controlling the water content to be 50 to 60 percent; S2, pre-composting the mixed materials for 15 to 20 days, and spreading the mixed materials into compost witha height of 15 to 18 cm; S3, inoculating Eisenia foetida into the compost, and laying a layer of soil on the surface of compost materials; controlling the moisture content of the compost material to be 60 to 70; and S4, placing the compost material in a cool and ventilated place, and regularly replenishing water and turning over the compost, wherein the composting time is 20 to 25 days. The methoddisclosed by the invention integrates two methods of natural compost and Aisheng earthworm compost, and simultaneously utilizes the benefits and advantages of the natural compost and Aisheng earthworm compost to better reduce the abundance of macrolide drug resistance genes in livestock and poultry excrement, reduce the release of macrolide drug resistance factors in breeding industry to the farmland environment, and reduce environmental pollution and potential risks to human health caused by recycling the breeding wastes.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and more specifically relates to a method for reducing the abundance of macrolide drug-resistant genes in livestock manure. Background technique [0002] The emergence and widespread spread of a large number of Antibiotic Resistance Genes (ARGs) due to the abuse of antibiotics has become one of the major threats to human health in the 21st century. While paying attention to the residue, fate and toxicity of antibiotics in the environment, the distribution, origin, environmental fate and impact on the environment and human health of ARGs have also become the focus of attention in the environmental field. Livestock manure is a major contributor to the growing burden of ARGs in the environment. Researchers at home and abroad have confirmed that the application of antibiotic residue manure in farmland will greatly increase the number and types of ARGs and drug-resistant bacteria in ...
