AI Technical Summary

Problems solved by technology

Because they have many shortcomings such as volatile, easy to decompose, poor stability, short action time and may decompose to produce harmful substances.
[0004] Inorganic antibacterial agents have the advantages of high safety, wide antibacterial range, long validity period, and anti-drug resistance. In recent years, their development and application have attracted attention from all over the world, and they are widely used in household appliances, leather, paint, wood, plastics, films, and ceramics. Antibacterial treatment of products such as paper, cosmetics, stationery and toys, but has not yet been used in the field of disinfection of livestock and poultry environments

Abstract

The animal and fowl disinfectant using nano material as carrier is made of copper salt and iron salt solution and nano montmorillonite through the processes of adsorption and ion exchange, in which the weight ratio of copper element and iron element is 1:0.25-0.50, and the content of copper and iron elements in the montmorillonite is 1.5-6.5%. Said invention can be used for disinfection for livestock shed, poultry housing, equipments, ainmals and fowl and seed egg, etc.

Description

technical field [0001] The invention relates to a livestock and poultry disinfectant with nanometer material as carrier and a preparation method thereof. Background technique [0002] Under the conditions of intensive, large-scale, automated and mechanized feeding and management of modern animal husbandry, the ecological environment of livestock and poultry breeding is deteriorating, and the pollution of pathogenic microorganisms is serious, which is easy to cause explosive infectious diseases, causing huge economic losses to the breeding industry. affect the development of the farming industry. The prevention of these infectious diseases mainly adopts vaccination, but due to the limited variety of vaccines, low efficiency and individual differences in livestock and poultry, there are still a large number of livestock and poultry infected with the disease, resulting in immune failure; there is a range of application of drugs for the treatment of these ...
