Lincomycin is a lincosamide antibiotic produced by Streptomyces lincolensis. Lincomycin is bacteriostatic in action inhibiting the protein synthesis predominantly by binding to the 50Sribosomal subunits of bacteria. Depending on the sensitivity of micro-organisms, and on the concentration of the active substance the protein synthesis inhibition antibacterial action can either be bacteriostatic or bactericide. Lincomycin is active against a wide range of Gram-positive bacteria, such as staphylococci, streptococci, β-haemolytic streptococci, corynebacteria, Erysipelothrix spp., and anaerobic bacteria, such as clostridia, as well as Leptospira spp. and Mycoplasma spp.


Target species

Broiler chickens



Royalprol is concentrated solution contain twin anticoccidials that provides a synergistic effect which is highly effective in the control of major coccidiosis causing Eimeria species of birds. Amprolium hydrochloride acts upon the first generation schizont to prevent merozoites production and that acts as competitive inhibitor of thiamine in the parasite metabolism. It exhibits high activity against E. tenella and E. acervulina. Ethopabate has anticoccidial activity especially against E. maxima and E. brunetti; and the synergistic combination of amprolium hydrochloride and ethopabate is effective against E. necatrix.
