Attribution of antibacterial and antioxidant activity ofCassia toraextract toward its growth promoting effect in broiler birds.
OBJECTIVE
The study was conducted to evaluate the attribution of antibacterial and antioxidant activity of methanolic extract ofCassia toratoward its growth promoting effect in broiler birds.


METHODS
A limit test was conducted forC. toraextract in Wistar albino rats. Phytochemical screening of methanolic extract of leaves ofC. torawas carried out. In-vitro antibacterial activity was measured by disc diffusion method. 1-day-old Ven Cobb broiler birds (n=90) were randomly allocated into three groups consisting of three replicates with 10 birds in each group. The birds of group T1 (Control) received basal diet, whereas birds of group T2 (Standard) received an antibiotic (Lincomycin at 0.05% in feed). The birds of group T3 (Test) receivedCassia toraextract (CSE) at 0.4 g/L in drinking water in addition to basal diet. The treatment was given to birds of all the groups for 6 weeks. Antioxidant activity ofC. torawas determined in blood of broiler birds. Cumulative body weight gain, feed intake, feed conversion ratio (FCR), dressing percent, and organ weight factor were evaluated to determine growth performance in broiler birds.


RESULTS
Phytochemicals inC. torawere screened. Sensitivity toEscherichia coliand resistant toStaphylococcus aureusandPseudomonas aeruginosawas observed inin-vitroantibacterial activity test. At the end of 6thweek, antioxidant activity reflected significantly (p≤0.05) lower level of erythrocyte malondialdehyde and higher levels of reduced glutathione (GSH) and GSH peroxidase in broiler birds of group T2 and T3 as compared to broiler of group T1. Mean cumulative body weight gain of birds of T2 and T3 were significantly (p≤0.05) higher as compared to T1. Mean FCR of birds of group T3 decreased significantly than group T1.


CONCLUSIONS
Supplementation ofC. toraleaves extract at 0.4 g/L in drinking water improved growth performance in broiler birds due to its antimicrobial and antioxidant activity. Therefore, it could be used as an alternative to antibiotic growth promoter in poultry ration.
