Studying the effectiveness of a feed additive for poultry "VITASIL 2 PLUS"

Feed  additives  based  on  organic  acids have a bactericidal and bacteriostatic effect that correlates with the input rate (dosage). The effect of the drugs is due to a cellular metabolic disorder of opportunistic bacteria and a change in the permeability of their cell membranes. The use of acid-based preparations helps to preserve the nutritional value of feed and prevent infection of animals and birds, which is an important aspect in maintaining  the  productivity  of  livestock.  This article examines the effectiveness of the new feed additive “Vitasil 2 Plus” against micro-organisms of the species Salmonella Enteritidis,  Escherichia  coli,  Pseudomonas  aeruginosa by adding to water and various types of raw materials and feed.Epizootic strains isolated from pathological material from birds from poultry farms in the  Russian  Federation  were  used  as  test cultures. The effectiveness of the drug was studied at low and high input rates, depending  on  the  type  of  substrate  being  studied. The following substrates were used: drinking water,  granulated  feed,  powder,  fish  meal and  soybean  meal.  Simple  (meat  peptone agar),  selective  (staphylococcal  agar)  and differential  diagnostic  (Endo  medium,  xyloselysine  deoxycholate  agar -  XLD  agar) nutrient media were used in the work.According  to  the  results,  it  was  found that the bactericidal and bacteriostatic effects of the feed additive, as a rule, correlate with high  and  low  input  rates.  As  a  result,  the effectiveness of the complex drug “Vitasil 2 Plus” has been proven against a number of microorganisms,  thereby  this  feed  additive can be used in the disinfection of feed and drinking water.
