Abstract: Esters or salts of 2-hydroxy-4-propyleyclohepta-2,4,6-trienone, and applications thereof in preparation of animal antibacterial agents and growth promoters used in feed. The esters or salts of 2-hydroxy-4-propylcyclohepta-2,4,6-trienone has a structural formula as shown in formula 1 or 2: in formula 1, R1 represents heptadecyl; and in formula 2, L is sodium, potassium, calcium, magnesium, zinc, copper or manganese. The esters or salts of 2-hydroxy-4-propyleyclohepta-2,4,6-trienone, as shown in formula 1 or 2, have high stability and safety, and good antibacterial and growth promotion effects, which make them preferable to be used as animal antibacterial agents and growth promoters in feed, and have a very good application prospect in the cultivation industry.

Abstract: Isopropoxy-phenylguanidine series salt as shown by the Formula (I) and an application thereof in preparing growth promoters for animal feed, wherein R is DL-lactic acid, methanesulfonic acid, 2-hydroxyethanesulfonic acid, citric acid, tartaric acid, benzoic acid, succinic acid, fumaric acid, maleic acid, acetic acid, sulfuric acid, phosphoric acid, or oxalic acid.

Abstract: An Application of p-methyl benzoic acid or a salt thereof as an additive for a feed or fed into drinking water for animals such as pigs, broilers, ducks, aquatic animals or other farmed animals, for preventing diarrhea and promoting growth, wherein p-methyl benzoic acid or a salt thereof is a type of acidifying agents for growth promotion.

Abstract: Diaminoguanidine derivatives in preparation of animal growth promoters used in feed. The diaminoguanidine derivatives have a structural formula as shown in formula (I), wherein R1 is methyl, ethyl, isopropyl, n-butyl, n-propyl, n-pentyl, n-octyl, n-tetradecyl, sec-butyl, 3-pentyl, cyclopentyl or benzyl. The diaminoguanidine compounds significantly improve the productivity of ducks if they are fed with the diaminoguanidine compounds. Productivity of pigs or chickens is also improved with such diaminoguanidine compounds.

Abstract: Disclosed are monoesters, inner complex salts or monoester salts of hexahydro-?-acid, and application thereof as animal feed additives. The compounds as shown in formula (I), (II) and (III) show low toxicity or non-toxicity to animals, and have higher stability and better growth promotion effects than those disclosed in other patents, which make them more suitable to be applied as growth promoters used in feed and have a very good application prospect in cultivation industry.

Abstract: The invention discloses application of an enrofloxacin salt in preparation of an oral preparation for pigs. The enrofloxacin salt is at least one of salts formed by enrofloxacin and metal ions, and the metal ions are zinc, copper, calcium, magnesium, iron, cobalt, manganese, chromium, silver or nickel. The enrofloxacin salt formed by the enrofloxacin and the metal ions can significantly improve the palatability of the enrofloxacin to pigs; furthermore pharmacokinetics and artificial infection prove that the enrofloxacin salt formed by the enrofloxacin and the metal ions does not affect bioavailability, so enrofloxacin salt can be developed into the oral preparation administrated via the digestive tract, for pig-raising without affecting normal feed intake of the pigs.

Abstract: The present invention discloses a fluoroethyl thiamine or salts thereof and application thereof in preparation of anticoccidial drugs. The structural formula of the fluoroethyl thiamine or salts thereof is shown as Formula (I). The fluoroethyl thiamine or salts thereof of the present invention have a remarkable anticoccidial effect, particularly on some coccidia which had resistance to other anticoccidial drugs, therefore the fluoroethyl thiamine or salts thereof of the present invention can be applied to preparation of anticoccidial drugs. Thus, the present invention provides conditions for development of new anticoccidial drugs.
