3 Introduction Stability Flavomycin ® compared with generics - Flavomycin 40 and 80 - in feed - in premix Conclusions Flavomycin
4 Introduction Wallhäuser et al in 1965, designated it as moenomycin Popular names: “bambermycin”, “flavophospholipol”, Flavomycin ® Initially recovered from: –Streptomyces bambergiensis –Three other Streptomyces spp. (S. ghanaensis, S. ederensis, and S. geysiriensis) are also identified Flavophospholipol is stable in: –the pH range from 7 to 9 –the presence of a large variety of enzymes (including trypsin, amylase, lysozyme, and lipase) Is a complex of five active, chemically related, compounds (A, A1/2 C1, C2 and C3), all (Huber et al 1965; Lenoir et al 1970) Characterized as very high molecular weight phosphorus containing glycolipids (1582 g/mol) Biologically, flavophospholipol had particular antibiotic activity against Gram positive bacteria: –no evidence of cross resistance to other antibiotics such as penicillin, tetracycline or macrolides (Wasielewski et al 1965)
5 Flavomycin ® Specifications Flavophospholipol content Moisture* (2% average) Heavy Metals oArsenic ≤ 5 ppm oLead ≤ 10 ppm oCadmium ≤ 5 ppm o Mercury ≤ 0.2 ppm * H 2 O content bound inside the Flavomycin molecule determines heat stability. The Flavomycin molecule is compact due to intra-molecular bounds and contains less H 2 O molecules, compared with generics.
16 Stability in different extruded feeds Flavomycin mixed into piglet and broiler feed undergoing extrusion process Flavomycin mixed into piglet and broiler feed undergoing extrusion process temperature and pressure at head of extruder: 145°C, 50 bar temperature and pressure at head of extruder: 145°C, 50 bar duration of passage through extruder: 5 to 10 sec. duration of passage through extruder: 5 to 10 sec. efficiency of extruder: 300 kg of feed/h values given are the average of 4 replicates efficiency of extruder: 300 kg of feed/h values given are the average of 4 replicates Piglet feedBroiler feed Content of active ingredientMg/kg% % Nominal2010020100 Actual before conditioning211051995 after conditioning199518.894 after extrusion, before cooling21.3106.520.3101.5 after extrusion and cooling20.810420.5102.5 Ref.: Trial report no. 1358 of International Institute of Feed Technology, Braunschweig, Germany
17 Stability under Expansion Conditions Ref.: Trial report no. 1457 of “Research Institute for Feed Technology”, IFF, Braunschweig, Germany Broiler Feed Production line consisted of mixer, conditioner, expander, pellet press and cooler; expander yielded 1t / hour two approaches were run: one using commercially practiced conditions the other using maximum conditions technically possible with equipment employed in heat, pressure and energy.

23 Conclusion oBetter stability vs. generics of the additive itself, in feed and in premix which is related to: –Compacter molecule, low nr of H 2 O molecules bound –Fermentation technology and knowledge –Fermentation medium composition –Quality of carrier and additives used in its composition oSuperior formulation –Available as dust free powder or as granule –Standardization technology –Spray dry technology oStrict compliance of the specs of the different components –Five different components (e.g. component A between 40 and 80% of the FLP complex) –Percentage of components is calculated in accordance to the detected potency (relative) –Water content, pH oInvestments in technology & Quality –Modern EU fermentation sites with the most important certifications: HACCP,GMP, GMP+, FDA, ISO.
