the effect of feed restriction methods on performance and prevention of ascites in arian male broiler chickens

in this experiment, randomized complete block design with four replications was used for evaluating of the effect of three feeding methods including: without feed restriction (control group), 6 hours feed restriction from 7 to 21 days and 4 hours from 22 to 28 days, 6 hours feed restriction from 7 to 14 days and 4 hours from 15 to 21 days on performance and ascites prevention of arian male broiler chickens in six weeks. body weight, feed intake, feed conversion ratio, mortality rate and the index of production efficiency were determined during the experiment. hematocrit and blood parameters were measured at 35 days of age. carcass characteristics and the right ventricle weight per total ventricle weight (rv:tv) ratios were determined and compared. feed conversion ratio and production index was improved by feed restriction from 7-21 days (p
