abstract
A research study was conducted to investigate growth promoting effects of neem leaves’ infusion on broilers. Thirty day-old chicks were randomly divided into four groups, designated as group-1, group-2 and group- 3. Each group was reared in sided house. Birds of Group-1, Group-2 and Group-3 were given 4% concentrated neem leaves (Azadirachta indica) infusion @ of 30ml and 50ml/litter of fresh drinking water respectively and group-3 was kept as control. Mean feed and water intake were higher (P<0.05) in control group as compared to others. The group-2 exhibited better (P<0.05) mean body weight gain, feed conversion ratio (FCR). Also, higher mortality was observed in group-3 as compared to group-1, and group-2. It was found that Neem (Azadirachta indica) successfully improved growth performance at the level of 50 ml/litter of fresh drinking water.
