  • chemical and / or microbial additives are commonly found during the manufacture of forage plant silages.
  • Chemical additives contain chemical substances, usually salts of organic acids, to act on the metabolism of microorganisms present in silage.
  • Microbial additives contain strains of homolactic or heterolactic bacteria that produce organic acids during the anaerobic phase of the ensiling process. All models found are part of the same technical field, but are completely distinct from the proposed invention.
  • the present model was developed as an alternative to additives commonly used in silages as it is a natural antibiotic with specific action on yeast and unicellular fungi, without exerting negative effect on the growth of desirable fermentative bacteria in silages.
  • natamycin in the ensiling process reduces the activity of yeast in the ensiling process, avoiding ethanolic fermentation and ensuring greater stability of the silage after the opening of the silos.
  • Natamycin is already used in the human food industry, mainly sausages, but is not yet used in the production of fermented feed (silage).
  • the product is already approved and used in the preservation of food for human consumption;
  • the cost of production is compatible with the benefits that natamycin has on silage, such as reduced ethanol production and increased aerobic stability of silages; - is water soluble and extremely practical to use;

It has crystalline structure and empirical formula C33H47N013, and acts in association with ergosterol, 24 and 28-dehydroergosterol, and cholesterol, present in the membrane of molds and yeast, but absent in bacteria, making natamycin a potent antibiotic inhibitor. yeast and mold, but without effect on bacteria.
  • natamycin as an additive in silage production allows selective exclusion of undesirable microorganisms in the process, such as fungi, molds and yeast, without harming the growth of desirable bacteria, especially acid-lactic bacteria.
  • the operation is simple and practical, simply adding the additive containing natamycin in solid powder form, or preferably diluted with water and / or other solvent, during the silage preparation process, where the forage plant is minced, natamycin added and compacted. in a storage structure called silo, which silo may have variable shape and size.
  • the application of the natamycin-containing additive in solid or liquid or other form may be done manually or by means of implements developed for this purpose, such as watering cans, spray pumps, or others. Natamycin inhibits growth undesirable microorganisms during the aerobic and anaerobic phases of the fermentation process, as well as after the opening of the silos.

For this reason, this technique should be well accepted by technicians and farmers in general, who use additives in the silage process.

Abstract

La présente invention concerne l'utilisation de la natamicine comme additif dans la production de produits d'ensilage, notamment dans le domaine technique des additifs pour la conservation de fourrages destinés à l'alimentation animale, et plus particulièrement l'utilisation de la natamicine comme additif pour ensilage, se caractérisant de façon innovante par l'utilisation d'un agent antifongique appliqué pendant la production de produits d'ensilage. L'invention présente la fonction d'inhiber le développement de levures, de champignons et de moisissures pendant les phases aérobie et anaérobie du processus de fermentation, ainsi qu'après ouverture du silo et exposition du produit d'ensilage à l'air.
