DIETARY EFFECT OF CORIANDER SEED POWDER ON THE PRODUCTION PERFORMANCE AND ANTIMICROBIAL ACTIVITY IN SONALI CHICKEN

Abstract

This study was conducted to evaluate the efficacy of dietary supplementation of coriander seed powder on production performance, dressing yield and antimicrobial activity in sonali chicken. For this purpose 150 day old chicks were randomly and equally assigned into five dietary groups namely T0, T1, T2, T3 and T4 having three replication. The chicks were brooded up to 8 days then randomly separated into replication wise in separate pen for rearing up to 8 weeks of age. Experimental birds in T2, T3 and T4 were provided with coriander seed powder @ 1 gm, 2 gm and 3gm per kg feed respectively, while T0 was provided with only plain basal diet and T1 was provided with 1 gm antibiotic. Results revealed that the feed intake was feed intake that was highest in T4 (1932g/bird) and lowest in T0 and T1 (1915 g/bird). The body weight gain was highest in T4 (766g±18.14) and lowest in T0 and T1 (674.66g±8.19), FCR value was highest in T0 (2.84±0.002) and lowest in T4 (2.53±0.001), meat yield was highest in T4 and lowest in T0 and in case of antimicrobial activity, the colony count of Salmonella and E. coli was lowest in T4 and highest in the control group. The results of this study indicated that final live weight gain and feed efficiency of the birds were significantly (p<0.05) higher in 3gm/kg coriander powder feed groups compared to those of control T0 group. This result also indicated that the body weight gain, feed intake and feed efficiency were increased as the doses of coriander seed powder increased. Meat yield parameters were not significantly differed among the treatment groups except breast carcass weight. The salmonella and E-coli colony were also significantly (p<0.05) differed among the treatment groups. Based on the result it could be concluded that the supplementation of coriander seed powder @ 3g/kg feed has potential effect on body weight gain, feed efficiency, feed conversion ratio, cool carcass weight gain and antimicrobial effect against pathogenic bacteria (Salmonella and E. coli spp), hence coriander powder in the diet could replace the synthetic antibiotics and could be regarded as natural feed additives and growth promoters for the production of Sonali chicken
