Performance, carcass characteristics, and immunity in broiler chickens fed dietary neem (Azadirachta indica) as alternative for an antibiotic growth promoter

This experiment was conducted to examine the effect of neem (Azadirachta indica) as an antibiotic growth promoter substitute on growth performance, carcass traits, and humoral immune responses in broiler chickens. A total of 192 one-d-old mixed sex broiler chicks (Ross 308) were weighted and randomly allocated to four treatment groups, each with 4 replicate pens of 12 chicks. The dietary treatments consisted of the basal diet (control), control+4.5 mg flavophospholipol/kg, or control+7 or 12 g neem fruit powder/kg.
