Effect of tulsi (Ocium sanctum) leaves extract as a growth promoter in broiler productio

This study was conducted to determine the efficacy of tulsi ( Ocimum sanctum ) leaves extract as a growth promoter in broilers from January to June 2013 under Dept. of Pharmacology, Bangladesh agricultural University, Mymensingh-2022, Bangladesh. 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 th and 35 th 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 th 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 Escherichia coli and produced zone of inhibition 0.5 cm and other was negative. Asian J. Med. Biol. Res. June 2017, 3(2): 226-232

Effects of aloe vera extract in drinking water on broiler performance

This experiment was conducted to evaluate the effects of dietary supplementation of aloe vera extract (w/v) on growth performance of broiler. The present study explored the potentials of medicinal plants Aloe barbedensis mixture in broiler performance. For this purpose, 120 day old chicks were randomly assigned into five treatment groups, namely T0, T1, T2, T3 and T4. Each treatment group contained 24 chicks. The chicks were purchased from a local chick hatchery named Nourish Poultry & Hatchery Ltd. Birds were brooded up to 10 days and then reared in separate flock for 35 days in an open sided house. Each treatment group was further replicated into three sub-groups and each contained eight birds. Experimental birds in T1, T2, T3 and T4 were provided with aloe vera extract (w/v) @ 05, 10, 15 and 20 ml per liter of drinking water while T0 was maintained as control group. Relevant data were recorded throughout the experimental period and subjected to statistical analysis. The data on growth parameters (body weight gain, feed consumption, feed efficiency, water intake) and feed cost and gross return per broiler were evaluated. The results of the study revealed that the aloe vera supplemented groups showed higher live weight gain than untreated group. Aloe vera supplemented groups showed more live weight gain in the terminal stages of the experiment. Aloe vera (w/v) extract supplemented groups performed the best feed efficiency. The live weight gain and feed efficiency were significantly (P
