A
dministration of antibiotics in animal feed at sub
therapeutic levels has been associated with growth
promotion; however their indiscriminate use has led to a
significant increase in the emergence of drug resistant strains.
Additionally, antibiotics are also being identified as emerging
environmental contaminants. Hence, it has become critical
to develop effective green alternatives to feed antibiotics,
without affecting livestock productivity. In this work, we
propose a novel formulation based on a combinational
approach comprising of a pyroligenous liquid, enzyme,
organic acid and yeast proteins that can be used in lieu of feed
antibiotics in poultry. The enzyme, organic acid and yeast
biomass have been produced by solid state and submerged
fermentation using agriculture wastes as substrates, thus
making the process cost effective. Qualitative tests by well
diffusion method have confirmed the antibacterial activity
of the pyroligenous liquid against several Gram positive
and gram-negative bacteria, with maximum activity against
Salmonella enterica
and
Listeria monocytogenes
which are
two of the most common bacterial pathogens associated
with poultry. Antibacterial activity was also observed at very
low concentrations of the pyroligenous liquid. The other
components are being tested for their antimicrobial activity
against common poultry pathogens.
