EFFICACY OF GUAVA LEAVES (Psidium guajava) SUSPENSION ON GROWTH, ANTIBACTERIAL AND HEMATOLOGICAL PERFORMANCES IN E. coli INOCULATED JAPANESE QUAIL

Abstract

The present study was designed to determine the growth, antibacterial and hematological effects of guava leaf (Psidium guajava) suspension in E. coli infected Japanese quail under the Department of Physiology and Pharmacology, HSTU, Dinajpur, Bangladesh, during September to October, 2017. A total of 40 quails of 10 days old were randomly assigned into four treatment groups named T0, T1, T2, T3 and each group contained 10 birds. GroupT0 and T1 were considered as negative and positive control, respectively. Group T2and T3 were treated with guava leaf (Psidium guajava) suspension and Doxycycline respectively. At 5 days interval, live body weights were recorded, bacterial loads in feces were counted and blood parameters were determined. Mortality was also observed in different treatment groups throughout the experiment. Body weights were significantly (P<0.05) increased in T2 and T3 group compared is T0and T1where as the bacterial load counts were significantly (P<0.05) decreased in T2 and T3compared is T0 and T1 groups. The present study was revealed that the mortality rate was significantly (P<0.05) higher in T1 group. There were significant (P<0.05) variation of total leucocytes count neutrophil, lymphocyte and eosinophil among the different treatment groups. But, the eosinophil count was insignificantly (P>0.05) varied among the treatment groups on the day 22th and 32th.
