Haemato-Biochemical Studies in Japanese Quails on Diet Supplemented with Neem (Azadirachta indica) Leaf Powder

摘要

An experiment was conducted to examine the effect of dietary supplementation of neem (Azadirachta Indica) leaf powder through feed on haemato-biochemical parameters of Japanese quails. For this purpose, 5 weeks biological feeding trial was conducted in a completely randomized block design (CRD) on growing broiler Japanese quails chicks from 1st to 6th weeks of age. Neem leaf powder was supplemented at graded levels (0, 0.1, 0.2 and 0.3 per cent) through feed to treatment groups (T_1, T_2, T_3 and T_4respectively) with 2 replicates of 15 broiler Japanese quails in each. At the end of six weeks, three birds from each replicate (6 birds/treatment) were randomly selected and blood was collected for haemato-biochemical study. The results of present study revealed that quails of T_3 and T_4 groups showed significantly (P<0.05) higher values of Haemoglobin (Hb), Packed Cell Volume (PCV), Total Erythrocyte Count (TEC), Total Leukocyte Count (TLC), Erythrocyte Sedimentation Rate (ESR), serum glucose and cholesterol as compared to control group of quails. There was a significant decrease in AST and ALT values in the neem leaf supplemented groups compared to control group. The study therefore revealed that neem leaf powder supplementation through feed at 0.3 per cent level is beneficial in improving haemato-biochemical values in Japanese quails.
