Abstract
In the present investigation, a feeding trial of 12 weeks of duration was conducted on 96 Uttara layers of 20 week age to study the effect of dietary supplementation of Arjun (Terminalia arjuna) bark powder on the production performance, egg quality parameters, egg composition, haemato-biochemical parameters, humoral immune response and economics of egg production. The laying hens were randomly divided in to four treatment groups (T0, T1, T2 and T3) four replicates of 6 birds each. The different groups were supplemented with Arjun bark powder at 0, 1g, 2g, 4g/100gm respectively to standard feed. Egg production, Egg quality parameters and Egg
composition were studied in different Phase Ⅰ (26th week of age), Phase Ⅱ(32nd week of age) and overall period. At the end of Phase Ⅰ and Phase Ⅱ blood was collected for haematobiochemical parameter analysis. The results of the present trial indicate that dietary inclusion of Arjun bark powder increase egg production, Egg weight and improve Feed conversion ratio significantly (P≤0.05) in T2 group. The shell thickness increases significantly however no significant difference observed in other egg quality traits. The blood picture revealed that Hb, PCV, TEC and TLC values in Arjun bark supplemented groups are significantly improved. No significant difference was observed in egg composition parameters. Serum glucose, cholesterol, LDL, SGOT and SGPT values in Arjun bark supplemented groups decreases significantly and HDL value increases significantly however no significant difference observed in other biochemical parameters. The average serum immunoglobulin concentration increases significantly in Arjun bark supplemented group. The average feed cost per dozen egg (Rs) decreases significantly in Arjun bark supplemented group. From the results of present study it can be concluded that Arjun bark can be used as herbal feed additive/ phytobiotc in poultry diet for higher production and enhanced immunity by incorporating 2 percent of Arjun (Terminalia arjuna) bark powder in the basal diet of Uttara chicken.
