Fourty number of day old broiler chicks were taken and after seven days divided into two groups A and B. The B group was supplemented with tulsi leaves extract @ 1ml/litre in drinking water. Weekly observations were recorded for live body weight gain up to 5th weeks and blood test was performed at 17<sup>th</sup> and 35<sup>th</sup> days age of broiler to study hematological changes between control A and treatment B group. No significant difference in hematological changes was observed in both treatment and control group in 1st week of age but significant change in body weight gain was observed on 35<sup>th</sup> day. They are 1500 g (control) and 1650 g (treated). The cost of production and economic study was carried out and it was observed that net profit in control group was 5.33 T.K/Kg broiler and in treatment group was 13.33 T.K/Kg broiler. Bacterial sensitivity test was positive in case of <em>Escherichia coli </em>and produced zone of inhibition 0.5 cm and other was negative.</p><p>Asian J. Med. Biol. Res.
