Abstract
This study was conducted under the Department of Physiology and Pharmacology to determine the effects of Neem and Nishyinda leaves supplementation on growth performance and GUT biosis in broilers. A total of 40 day old broiler chicks were divided into four groups A, B, C and D. Group A was considered as control, fed only with commercial broiler ration. Group B supplemented with formulation of 2 gm grinded Neem leaves, Group C with 2 gm grinded Nishyinda leaves and Group D with 1 gm grinded Neem leaves plus 1 gm grinded Nishyinda leaves per liter of water respectively. Observations were recorded for live body weight, weight gain, feed consumption, feed efficiency, hemato-biochemical parameters and GUT biosis specially the parasite of birds in six weeks. Body weights were increased significantly (p<0.05) in all treated groups in respect to the control and highest was recorded in combine Neem plus Nishyinda supplemented groups (Group D). No significant (p>0.05) differences were observed among the groups for PCV and TEC values. Hb content increased and ESR decreased significantly (p<0.05) with combine Neem plus Nishyinda supplemented group (Group D). The serum SGOT and SGPT levels were also decreased with the same kind of supplementation. In treatment group there was significantly decreased of parasitic eggs, but in case of control group no decrease of parasitic eggs. There was no significant pathological change in any internal organs of the broiler of treated groups. Best result was found in the group D. The present study reveals that combine supplementation of Neem plus Nishyinda gives better result over other groups in respect to body weight gain, feed conversion ratio, hemato-biochemical parameter and profitability without making any health hazard of the broilers.

Highlights
This experiment was conducted to study the efficacy of grinded Neem (Azadirachta indica) and grinded Nishyinda (Vitex nigundo) leaves as a growth promoter in broiler and was held under the Department of Physiology and Pharmacology. 40 day old chicks were randomly divided into 4 groups (A, B, C and D) for assessing the efficacy of grinded plants leaves as growth promoter on broilers
Forty healthy commercial broilers were divided into four groups (n=10) to carry out this research work. In this experiment, grinded Neem and Nishyinda leaves were studied in terms of growth promoter on broilers because we showed that these herbal plants are available, cost effective and produced broilers are free from any drug residual effect and suitable for human consumption
From this experiment we found that, between the control group and the treatment group of birds, the Neem plus Nishyinda (D) groups are more profitable than any other groups
Summary
Poultry production especially chickens and ducks has attained an important place in agricultural economy of Bangladesh both through contribution to GDP and employment especially in urban areas. From poultry people get egg, meat which fulfills the protein demand of huge amount of people of Bangladesh. There are so many sources of protein but it is not possible to fulfill the demand without broiler. Because the duration of broiler rearing is very short and within 36 - 42 days it is ready for marketing and suitable for human consumption. It brings very short time return to farmer. There are various Bacterial, Viral, Mycoplasmal, Fungal and Parasitic disease
