DIETARY AND ANTIBACTERIAL EFFECT OF BASAK (ADHATODA VASICA) LEAVES ON PERFORMANCE OF SONALI CHICKEN

Abstract

This study was conducted at the department of Dairy and Poultry Science, Hajee Mohammad Danesh Science and Technology University, Dinajpur. An experiment was conducted to evaluate the performance and antibacterial effect of basak on sonali chicken. A total of 120 day old chicks were randomly divided into five treatment groups namely (T0, T1, T2, T3 and T4) having three replications in each treatment group. Brooded chicks were randomly separated into replications wise separate pen to rear up to 8 weeks. Each treatment group contains 27 birds whereas each replication contains 09 birds. Experimental birds in T1, T2 and T3 were provided basak leaves powder meal @ 1.5%, 3% and 4.5% of feed while T4 provided growth promoter and T0 was provided only normal feed was considered as control group. The results of this study was indicated that final live weight gain and feed efficiency of birds was significantly (p<0.05) higher in T1 group (735.78±6.39g) that received @1.5%basak leaves powder meal compared to control T0 group (620.26±3.78g). This result also indicated that body weight gain, and feed efficiency were increased at dose rate 1.5% basak leaves meal. In case of meat yield parameters there was no significant (P>0.05) difference among treatment groups except carcass weight, breast meat weight and dressing percentage. The breast meat weight, carcass weight and dressing percentage was significantly (p<0.05) higher in treatment T1 group compared to control group. In bacteriological test E. coli and Salmonella load was decreased significantly in treatment group as compared to the control group. The lowest feed cost was found in T1 and highest in T4 group. Net profit Tk. was found maximum in T1 (40.9±2) followed by T2 (27±4), T3 (22.4±4) T0 (20.7±3.2) and T4 (19.7±2.0) respectively. Based on the result it could be concluded that basak leaves meal @ 1.5% can be used as growth promoter for production of chicken.
