Efrotomycin (ET) is an antibiotic obtained by the incubation of Nocardia lacamduranns, and composed of 4 components: Efrotomycin A1, Efrotomycin A2, Efrotomycin B1, and Efrotomycin B2. Although its antibacterial spectrum is narrow, ET has an antibacterial effect on part of the Grampositive bacteria and on treponema, and has a growth promoting effect on pigs etc. ET is a pure-grade antibiotic that was designated as a feed additive. Under the brand name Producil Efrotomycin was indicated for increased rate of weight gain when incorporated into complete swine feeds at 3.6 to 14.5 g/ton. This antibiotic is a potent inhibitor of bacterial protein synthesis by interfering with peptide transfer reactions associated with the elongation factor Tu.

Sample Use Guides

In Vivo Use Guide

Pigs: Dosage: Form: A free-flowing, non-dusty, granular premix containing 32 grams of efrotomycin activity per kilogram intended for incorporation in swine rations. Route of administration: Orally as an additive to swine feeds. Recommended dosage: The effective range for efrotomycin use in swine is 4 to 16 ppm (3.6 to 14.5 g/ton) inclusive for increases in average daily gain and 4 ppm (3.6 g/ton) for improvements in feed efficiency. Blend Producil into complete swine feeds at 4 oz - 16 oz per ton to supply 3.6 g - 14.5 g efrotomycin per ton of feed.

Route of Administration: Oral
