Gamaxine US Broiler Breeder Trial Maria Dashek

Trial Overview History: Mid-sized broiler producer in USA had high mortality in broiler breeder pullets associated with secondary opportunistic infections (i. e. E. coli). Objective: Test the effect of Gamaxine on the livability and productivity parameters of broiler breeders. Administration: The farm had 4 houses, and 2/4 houses were administered Gamaxine at 1 L/ 5, 000 birds on days 3, 17 and just before move to breeder barns (wk 18).
