Problems solved by technology

[0002] At present, with the rapid development of social economy, the breeding industry is also developing rapidly. The feed and additives consumed by self-employed rural households to intensive large-scale farming are increasing exponentially. Especially for the formulation and production of feed additives, the market has never been The standardized operation process has led to a mixture of various additives. In order to pursue profits, a small number of individuals and manufacturers have ignored the safety of feed production and mixed in raw materials that cannot be added, making feed additives a problem product and greatly affecting feed additives. safety, which further affects the safety of common people's food

Abstract

The invention relates to a feed additive, in particular to a feed additive quinocetone and a preparation method thereof and belongs to the technical field of chemical engineering. In the preparation method, o-nitroaniline is used as the starting raw material and the method comprises the following steps: oxidizing with sodium hypochlorite, and then reacting with acetylacetone and benzaldehyde to obtain quinocetone. Quinocetone can inhibit the synthesis of bacterial DNA to inhibit the growth of pathogenic microorganisms in the digestive tract, prevent or reduce diseases, protect good intestine bacteria and intestinal wall from the harms of microorganisms or parasites and promote the digestion and absorption of various nutrients. Therefore, the growth of animals can be promoted and the feed conversion rate can be increased.
