Abstract
To investigate the effect of graded level of acetic acid on the production performance and carcass characteristics of broiler, present study was conducted for a period of 35 days in a controlled shed. A total of 240 Cobb 500 day old broiler chicks were divided into four dietary treatment groups (T0, T1, T2 and T3), each group with three replications and each replication having 20 birds. Control group (T0) birds were fed with the basal diet without any acetic acid. Birds of T1, T2 and T3 group were treated with 0.1%, 0.2% and 0.3% acetic acid in drinking water, respectively along with basal diets. Recorded data were analysed in SPSS software by using ANOVA and significance level was considered as 5%. Results showed that, acetic acid has significantly (P<0.05) improved live weight, live weight gain, feed conversion ratio (FCR) and some meat characteristics (carcass weight, thigh weight and breast weight) of experimental broilers. However, there were no significant (P>0.05) differences were observed between control group and acetic acid treated groups of birds in terms of feed intake, dressing percentage, liver weight, heart weight and abdominal fat. Net profit was higher in birds treated with acetic acid than the control group and the best performances were observed in the birds treated with 0.3% acetic acid.

Statistical analysis Collected data were spread at MS excel sheet (Microsoft office excel–2007, USA) and subjected to analysis of variance (ANOVA) in a completely randomized design (CRD) employing Statistical Package for Social Science (SPSS) version 20 and results were expressed as Mean ± SEM, data were considered significant at 5% level of significance
Birds treated with 03% acetic acid (T3) with drinking water had highest final live weight at 35 days of age (1897.25 g) and birds treated with no acetic acid in drinking water had the lowest final live weight (1740.87g), while birds treated with 0.1% (T1) and 0.2% (T2) acetic acid had significantly higher live weight (1789.33 g and 1855.50 g, respectively) than the control group (1740.87g)
Summary
Poultry sector is one of the most vibrant segments of agriculture sector in Bangladesh. Farmers often extensively uses antibiotics in poultry production to promote growth (Barceló, 2007) and protect the health of birds by modifying the immune status of broiler chickens (Lee et al, 2012). This is mainly due to the control of gastrointestinal infections and microbiota modification in the intestine (Dibner and Richards, 2005). No notable work has been done on the potential use of acetic acid on growth performances and carcass characteristics of broilers in Bangladesh except the work of Islam et al (2008) and this type of study may encourage Bangladeshi broiler farmers to use organic acids instead of antibiotics. The present study was conducted to investigate the effect of dietary supplementation of acetic acid on production performance, carcass characteristics and economic efficiency of broiler production
