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. Res. Agric., Livest.

分级乙酸处理肉鸡生产性能及胴体特性
为研究醋酸分级水平对肉鸡生产性能和胴体特性的影响,本试验在对照棚内进行了为期35 d的试验。选取240只科布500日龄肉仔鸡,分为4个饲粮处理组(T0、T1、T2和T3),每组3个重复,每个重复20只鸡。对照组(T0)饲喂不添加乙酸的基础饲粮。T1、T2和T3组分别在基础饲粮的基础上添加0.1%、0.2%和0.3%的乙酸。记录资料在SPSS软件中进行方差分析,显著性水平为5%。结果表明:对照组与乙酸处理组的采食量、屠宰率、肝脏重量、心脏重量和腹部脂肪均有显著差异(P0.05)。用醋酸处理的鸡的净利润高于对照组,用0.3%醋酸处理的鸡的生产性能最好。阿格利司》。,力所能及的。鱼类。8(3):311-319,December 2021
