Black Seed Extracted Oil For Enhancing Productive And Physiological Status Of Broiler

Abstract

Effect of extracted black seed oil (BSE) on broiler performance was evaluated. Four groups of 60 chicks were divided in this study. The first group (control) fed basal diet, the other groups fed diet supplemented with 0.1, 0.2% extracted oil (BSE1 & BSE2) and 0.2% Flavophospholipol as antibiotic growth promoter (AGP). The results showed (P≤ 0.05) higher body weight at 21 and 35 days of age for the group supplemented with BSE2 compared with other groups. Carcass and breast were greater (P ≤ 0.01) in birds fed diets supplemented with either the two supplementations of BSE or AGP than control group. Significant high concentrations have been recorded in total protein and globulin in BSE2 group followed by BSE1 and AGP. The A/G ratio was declined from 0.523 in control to range of 0.319 to 0.431 in the others. The activity of amylase enzyme recorded more than 5 folds in BSE2 and twice in BSE1 compared with both AGP and control groups. Protease activity in stomach recorded more than 4 folds in BSE2 and 2 folds comparing with AGP and control groups. This study showed encouraging improvement in immune response accompanied by live body weight for broilers fed diets supplemented with BSE compared with the other groups. It could be concluded that BSE addition to broiler diets may improve performance and immunity characteristics. Keywords: extracted black seed oil; Flavophospholipol; broiler performance; immunity.
