abstract
A study was conducted to evaluate the impact of a phytobiotic supplemented in different form in the diet on the performance, changes in hepatic marker enzymes and broiler’s carcass characteristics. Two hundred fiftyVencobb-400Y strain broiler chicks were divided into five groups with 10 chicks in each five replicates. Each group was fed with different treatment i.e. a basal diet (NC), basal diet with antibiotic (PC), basal diet with herbal mixture powder (HP), basal diet with aqueous extract (AqE) and alcoholic extract of herbal mixture (AlE).The performance, liver function and carcass parameters of birds were ascertained. There was significantly (P<0.05) higher body weight gain (BWG) in AlE group compared to PC and NC group birds. Feed intake of AqE and AlE group birds were significantly (P<0.05) higher than NC, PC and HP group birds. Energy efficiency ratio (EER) and protein efficiency ratio (PER) of AlE groups was similar to PC, however significantly (P<0.05) higher than NC group broiler chickens. The serum ALT and AST level were significantly (P<0.05) lower in the birds that supplemented herbs in any form powder, aqueous or alcoholic. No significant effect of different treatments on broiler’s dressed weight, giblet weight and drawn yield were observed. So, AlE supplementation had hepatoprotective impact and it improves performance of broiler chicken.
