USE OF TULSI LEAVES JUICE AS GROWTH PROMOTER ON PRODUCTION PERFORMANCE IN SONALI CHICKEN

Abstract

This study was conducted under the Department of Dairy and Poultry Science Hajee Mohammad Danesh Science and Technology University. Objective of the research was to evaluate the effect of tulsi leaves (Ocimum sanctum) juice supplementation in drinking water as a growth promoter in sonali chickens. For this purpose, 120 day old chicks were purchased from Rafid Hatchery Ltd. After 7 days of brooding the chick were randomly divided into four treatment groups namely, T0, T1, T2, and T3 having three replications in each treatment group. Brooded chick was randomly separated into replication wise in separate pen for rearing 8 weeks. Each treatment group contain 30 birds where as each replication contain 10 birds. Experimental birds in T1, T2 and T3 were provided tulsi leaves juice @ 1.5, 3 and 4.5 ml per liter drinking water while T0 was provided without tulsi leaves juice. The results of this study was indicated that final live weight gain and feed efficiency of birds was significantly (p<0.05) higher that received @ 3 ml/L tulsi leaves juice compared to control T0 group. This result also indicated that body weight gain, feed intake and feed efficiency were increased at dose rate 3 ml/L tulsi leaves juice. Meat yield parameters there were no significant difference among the treatment group except breast meat weight and dressing percentage. In bacterial test E. coli and Salmonella load was decrease significantly in treatment group as compared to the control group. Data obtained feed cost, lowest was seen in tulsi leaves juice treated group T2 and highest in untreated T0 group. Net profit was found maximum in T2 (26.52±1.20Tk.) then T1 (20.36±1.33Tk.), T3 (17.76±1.11Tk.) and T0 (12.96±1.12Tk.) respectively. Based on the result it could be concluded that the supplementation of tulsi leaves juice 3 ml/L in drinking water has potential used as growth promoter for production of sonali chicken.
