Abstract
The invention discloses series salts of robenidine and an application thereof in preparation of an animal feeding growth promoter. The series salts of robenidine have a structural formula shown in the formula (1), wherein R is DL-lactic acid, methanesulfonic acid, 2-isethionic acid, citric acid, tartaric acid, benzoic acid, succinic acid, fumaric acid, maleic acid, acetic acid, sulfuric acid, phosphoric acid or oxalic acid. Through feeding experiments, the research, for the first time, discovers that after application of the series salt compounds of robenidine, the production performance of ducks is improved obviously. Through animal feeding experiments, the research also discovers that after application of the series salt compounds of robenidine, the production performance of sows and hens is improved.
Description
Technical field: [0001] The invention belongs to the field of animal feed for livestock and poultry, and in particular relates to a series of salts of prohexidine and its application in the preparation of growth promoters for animal feeding. Background technique: [0002] Feed growth promoters include biologically active substances with various chemical structures and their preparations with multiple mechanisms of action, which make an important contribution to improving feed conversion rate and animal husbandry production efficiency. However, many antibiotic growth promoters have been banned or will soon be banned due to the problem of resistance transmission. [0003] Therefore, how to screen safe and efficient feed growth promoters that have no human medical use and no cross-resistance to human antibiotics, especially non-antibiotic and non-hormonal feed growth promoters is a problem. This study solved this problem. [0004] Chlorhexidine hydrochloride is traditionally ...
