Placement
At hatch, chicks and poults have underdeveloped gut microflora, making them more vulnerable to harmful bacteria.
Flush water lines with Avi-Bac before placement, then keep birds on it for the first 3–7 days to seed the gut with beneficial bacteria and strengthen early immunity.

Feed Changes
Switching nutrient or ingredient levels disrupts gut microflora and can allow pathogens to gain a foothold.
Apply Avi-Bac 2 days before and 2 days after a feed change to maintain microbial balance and protect 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.
