Public demand to recude AB in animal feed

Table 1: Ban of Antibiotic Growth Promotors in feed

1986

Sweden

1997

EU: Ban of Avoparcin

1999

Ban of Batritacin, Siramycin, Tylosin, Virginiamycin

2003

EU: Nifursol

2006

EU: complete ban

  • f AGP

(Flavo/Avilamycin)

Consequences:

Search for alternative Gut Stabilizers Increasing use of therapeutic Antibiotics Higher Incidence of Enteritis/ Dys- bacteriosis

Intention of AB Growth Promotors

  • Reduction of Subclinical infections
  • Reduction of microbial metabolites in the gut, which will limit performance of animals
  • Reduction of Microbs which will utilize Nutrients
  • Increase of Nutrient absorption by the animal trough a thinner gut wall.

Better FCR Higher End weights Lower Mortality

Example Flavomycin

  • Phosphoglykolipid from Streptomyces ghanaensis
  • 1-2 mg/kg feed
  • Anitmicrobial action against gram positive Baktria inside the gut (no transmission to

the blood stream)

  • Mode of action:
  • Inhibition of growth of gram positive bakteria by inhibiting the Biosynthesis of

Murein (structual substance of the cell wall)

  • Cell death

Currative AB in Poultry

  • Gut health
  • Respiratory system

Probiotics

Indirect inhibiton of harmfull bacteria Competitve exclusion Long time of application needed to transform gut mircobiota

Enzymes

NSP Enzymes: reduction of viskosity  better digestiability of nutrients Influence on bactieria which are deconjugating bile acid (Clostridia)

Organic acids

pH reduction in feed or intestine Enzyme activation, therefore better digestability

Prebiotics

Oligosaccharides which will feed the positive microbiota Modification of Microbiotia, which will lead to increase

  • f lactic acid and

propionic acid production

Herbs, essential Oils

Influence on feed intake, Enzym segregation, Impact on Mikrobiotia, Respiratory tract

Conclusion

  • Reduction of Antibiotic in the feed possible
  • Feed formulation has to be adapted
  • Feed does not become more expensive
  • Performance and weight gain can be on the same leve without

AGPs
