From one day age to 45 days age with concentrations (5 ml chicks stage, 5 ml grower chicks and 10 ml finishers stage/100 birds a day). As far the Activity of liver enzyme (AST-ALP-LDH) in blood sera in ages (15, 30, and 45 days) from the age of bird. The p Activity was less than 0.05 in all the breeding stages.
