PROFITABILITY OF USING SALBUTAMOL (A BETA-ADRENERGIC AGONIST) AS A GROWTH PROMOTER OF BROILER CHICKENS

Abstract

This study was conducted to evaluate the effect of salbutamol (beta-adrenergic agonist) on performance of broiler chickens. A total of 60 (Cobb) day-old broiler chickens were randomly assigned to 3 groups each 20 birds per pen. Groups include: control, 5, and 15 mg salbutamol per kg diet. The experiments was designed for 3 weeks. Results from this experiment indicated that. growth rate, body weight gain and food consumption were significantly increased by using 5 mg/kg salbutamol while a significant decrease was attained by 15mg/kg salbutamol as compared with the control group (P ≤ 0.05). The feed conversion ratio was significantly increased by 5 mg/kg salbutamol compared with the control group (P ≤ 0.05).Meanwhile, eviscerated and deboned carcass were significantly increased by 5mg/kg salbutamol but decreased significantly by 15mg/kg salbutamol as compared with the control group (P ≤ 0.05).In conclusion, it seems that feeding salbutamol as a beta-adrenergic agonist, can improve growth performance in broiler chickens at dose of 5mg/kg.
