Adding probiotics to your flock's diet is beneficial for establishing and maintaining healthy intestinal microflora. The most effective means of administering probiotics is through the use of a liquid or powdered form mixed into the drinking water. Probiotics help by increasing the population of good bacteria in the intestines, to help fight off the bad bacteria. The most frequently used probiotics include Lactobacilli and Bifidobacteria genus of bacterial organisms.
These are Gram-positive bacterial organisms that by consuming oligosaccharides, produce lactic acid, acetic acid, ethanol, and formic acid. B. longum has shown to be beneficial for inhibiting harmful campylobacter bacteria in chickens.
These are a type of beneficial bacterial that are collectively referred to as lactic acid bacteria, which, like Bifidobacteria, metabolize oligosaccharides to produce lactic acid as the primary end product. L. reuteri and L. fermentum have shown to be of benefit to chickens.
Both lactobacilli and bifidobacteria are known to be members of the intestinal microbiota in animals and humans; their presence is important for the maintenance of the GIT microbiota.
Streptococcus faecium and S. bovis have shown beneficial for inhibiting invasion of harmful Salmonella bacteria.
