abstract
This study aimed to determine the effectiveness of Nishyinda (N) leaf, Ginger (Z), and Turmeric (T) extract (NTG extract) as a growth promoter in the broiler. A total of 20-day old broiler chicks were bought from Kazi Farms Limited, Bangladesh, and randomly split into two after seven days. The control (A) group was not supplemented with NTG extract in drinking water while NTG extract @ 1ml / litre in drinking water was supplemented to group B. Weekly measurements were reported for live body weight to gain up to 6 weeks and blood testing was performed at broiler's age of 21 and 42 days to assess hematological differences between control and treatment groups. The recorded FCR value was 1.93 and 1.88 respectively in control and treatment groups, which indicates that the NTG extract played a vital role. The mortality rate in Group A, recorded was 20%. Results showed that supplementing NTG extracts (Group B) in broilers resulted in a significant increase (P<0.05) in mean live weights compared to control (A) group whereas, the hematological parameters (TEC, PCV, Hb, ESR) showed no significant (p>0.05) difference as compared to control group.
