EFFECTS OF NEEM LEAVES, GINGER AND BLACK PEPPER EXTRACT AS A GROWTH PROMOTER IN BROILERS

This study was conducted to determine the efficacy of Neem leaves (N), Ginger (G) and Black pepper (BP) NGBP extract as a growth promoter in broilers. A total of 20 day old broiler chicks were purchased from Kazi Farms and after seven days divided into two groups A and B. No vaccination schedule was practiced and no antibiotics were added in ration. The A group was not supplemented with NGBP extract in drinking water. The B group was supplemented with NGBP extract @ 1ml/litre in drinking water for consecutive 5 weeks started from 7^th day of experiment. The FCR value in Group A was 1.89 and in group B was 1.88 as a result it indicated that NGBP extract played vital role to protect mortality in Group B. From this initial study this may be concluded that production of broilers in by using NGBP extract was economic than control group. In Bangladesh broilers production is mainly organized by unemployed and its demand is very high because it supports marketing within 35 – 42 days. Short return of money but major problems is cost of production. The treatment group B recorded statistically non- significant for live body weight at 1st and 2nd weeks than that of control group A but found statistically significant at 3^rd (p<0.01), 4^th (P<0.05) and 5^th (P<0.01) weeks of age and the Hematological parameters (TEC, PCV, Hb, ESR) showed statistically significant (p<0.01) difference as compared to control A group.
