Abstract
This experiment was conducted to study the effect of early feed restriction by diet diluted with wheat bran during the first two weeks on the productive and physiological characteristics of broiler. A total of 600 unsexed broiler chicks , one day old , Arbor Acar broiler chicks , were randomly distributed into four treatment groups. Chicks in T1 used as control group and fed standard ration through out of the experimental period which is lasted at 7 week of age. Chicks in T2 were fed diet diluted with wheat bran at the level of 15% and used for feeding during the period from 4-14 day of age. After that the chick were fed the standard ration until the marketing age (7 weeks). The dilution percentages of the diet were increased to 30 and 45% for chick in T3 and T4 respectively. The data showed that a compensatory growth was observed among birds in all diet dilution groups (T2 , T3 and T4) and their final body weight at 7 weeks of age were statistically different from the control group. Diet dilution significantly (P > 0.05) lowered the mortality due to Ascitis and Sudden death syndrome (SDS). The early feed restriction had not significantly affected the feed consumption , feed conversion , blood characteristics and the titer of antibody against Newcastle disease virus. However , the production index (PI) and economic figure (EF) were significantly increased (P > 0.01) in diet dilution groups when compared with control.
