Placement
At hatch, chicks and poults are still developing their gut microflora, making them more vulnerable.
Flush water lines with Avi-Bac before placement. Keep birds on Avi-Bac for the first 3–7 days to help seed the gut with beneficial bacteria.

Feed Changes
Feed changes are an adjustment period for gut microflora.
Apply Avi-Bac 2 days before and 2 days after a feed change to help support microbial balance and digestive health

After Antibiotic Use
Antibiotics target harmful bacteria but can also wipe out beneficial strains. Administer Avi-Bac for 3–7 days following withdrawal to restore healthy gut populations and support immune recovery.
