چکیده

The present study was conducted to investigate the effect of xylo-oligosaccharide and xylanase supplementation on growth performance, carcass characteristics, nutrient digestibility, intestinal histology broilers. Six hundred day-old chicks (ROSS-308) were divided into four experimental groups (i.e. T1, T2, T3, T4). Each unit had six replicates 25 chicks/replicate. Following treatments offered: T1= positive control (PC, commercial diet); T2=negative (NC, basal T3= NC+Signis®; T4= NC+XOS+Xylanase. experiment from 1 35 days broiler age during this trial data regarding performance (feed intake, weight gain) recorded feed conversion ratio calculated. At end experiment, 2 birds every replicate randomly selected slaughtered get characteristics giblet's weight. Intestinal tissues (duodenum, jejunum, ileum) also collected for histological analysis.

Results showed that duringthe starter phase, non-significant mortality whereas a significant observed body gain intake. Treatment C significantly higher intake D than negative groups.
