Abstract:
To study the effect of dietary supplementation of amla fruit powder on haemato-biochemical parameters of broiler chicken, 300 commercial broiler chicks were randomly distributed into six treatments having five replicates consisting of ten birds each. The chicks fed with standard basal diet in two different growth phases i.e. starter (0-28d) and finisher (29-42 d). The first group was kept as control (T₁) and given the basal diet without antibiotic, while second group (T₂) was given basal diet with antibiotic. In third (T₃), fourth (T₄), fifth (T₅) and sixth (T₆) groups, basal diet was supplemented with amla fruit powder @ 0.25%, 0.50%, 0.75% and 1%, respectively. The birds were weighed fortnightly to calculate performance parameters viz. feed intake, body weight change and FCR. At the end of the feeding trial (6^th week), blood samples were collected from one broiler per replicate, making five samples per treatment and thus a total of 30 samples were analyzed using automatic haemoanalyzer.% mean values for heterophil ranged from 23% (T₆) to 29% (T₁) and lowest heterophil count was found in T₆ group and this differ significantly from the control group. Mean values for lymphocytes ranged from 61.80% (T₁) to 68.40% (T₆) and differs significantly among amla supplemented and the control group. Mean values for this ratio ranges between 0.336 (T₅) to 0.473(T₁) and significantly lowest ratio was found in T₅ and T₆ group as compared to control group. Values of serum cholesterol content under different treatments were ranged between 135.79 mg/dl to 153.47 mg/dl and significantly lowest serum cholesterol value was reported in the 1% amla fruit powder (T₆) supplemented group. Supplementation of amla fruit powder results in decreased levels of total cholesterol and LDL, whereas HDL content of meat was increased as compared to control.
