EFFECTS OF ADDITIONAL PROTEIN AND GROWTH PROMOTER ANTIBIOTICS ON GROWTH AND HEMATOBIOCHEMICAL PARAMETERS IN BROILER

Abstract

Broiler chicks (COBB 500) were used to evaluate the effect of protein and growth promoter antibiotic (GPA) supplementation on growth performance and hemato-biochemical parameters. A total of 20, 9 days old boiler chicks in four different groups (n=5) with an initial body weight of 251±2.98 gm were used. Group A was considered as control and fed with standard commercial boiler ration. Group B was supplemented with protein concentrated. Group C, growth promoter antibiotic (GPA) and Group D with protein and GPA combined for next 21 days. The body weight of different groups of birds were increased significantly (p<0.0l) in all treated groups in respect to control and highest weight gain was recorded in (Group D) supplemented with protein and GPA. The meat weight and weights of some selective organs (viscera, abdominal fat and skin) at the end of the experiment were significantly (p<0.01) different. Both single and combined supplementation of protein and GPA increased total RBC andHb concentration (p<0.01) and PCV (p<0.05) compared to control. The highest RBC, Hb and PCV were found in the combined protein and GPA supplemented group. The serum ALT level was decreased significantly (p<0.01) in treatment groups compared to control. Urea level was increased significantly (p< 0.01) in each treatment groups compare to control. Supplementation of only protein (Group B) resulted in higher serum urea level compared to GPA (Group C) and combined supplementation of protein and GPA (Group D). The present study revealed that combined supplementation of protein and GPA gives better performance in broiler production.
