EFFECT OF PAPAYA LEAVES (Carica papaya) SUSPENSION ON JAPANESE QUAIL (Coturnix japonica)

Abstract

This work was conducted for a period of two months from October to November 2017 at Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh to evaluate the effect of papaya (Carica papaya) leaves suspension (PLS) on Japanese quail. One hundred and twenty (120) female Japanese quails (Coturnix japonica) ten days old were randomly assigned into four groups with three replications (each containing ten birds) per treatment to investigate the comparative efficacy of papaya leaves suspension (PLS) and doxycycline on bacterial load and blood constituents on E. coli infected Japanese quail. For this purpose, birds were assigned into control group (T0), E. coli treated group (T1), E. coli plus PLS treated group (T2) and E. coli plus doxacil-vet powder treated group (T3). All groups were supplied E. coli orally except T0 group and after 24 hours T2 & T3 groups were treated with PLS (0.25%) and doxacil-vet powder suspension (1g/2lit) respectively. EMB agar was used for CFU and microbial load significantly (P<0.05) decreased in T2 & T3 group where significantly (P<0.05) increased in T0 and T1 group. TEC, Hb, PCV & ESR in different treatment groups were almost similar and the differences were statistically non-significant (P>0.05) except TLC which was statistically significant (P<0.05) and the highest TLC was recorded in T2 group. Furthermore, ten days old sixty (60) female Japanese quails were randomly assigned into two groups named T0 (control diet) and T1 (0.25% PLS) with three replications (each containing ten birds) per treatment to investigate the effect of papaya leaves suspension on live body weight, egg production and egg quality of Japanese quail. Egg weight, egg shape index, shell plus membrane weight, shell plus membrane thickness, haugh unit, albumen index and yolk index were performed for the determination of egg quality. The body weight of T0 and T1 at 65th day were 164.95 and 182.32 g respectively which was statistically significant (P<0.05). The Hen-day-egg production (HDEP) observed for 15 days were 68.29% and 73.10% in T0 and T1 group respectively which statistically significant (P<0.05). In the treatment groups the external and internal quality of eggs (Egg weight, egg shape index, shell plus membrane weight, shell plus membrane thickness, haugh unit, albumen index and yolk index) were almost similar and the differences were statistically nonsignificant (P>0.05).
