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: 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.
