Abstract
This study was conducted in poultry farm of the general authority of agriculture research in Alrashidia during 2012 on 280 day old white unsexed quail chicks reared under standard conditions for 14 days of age. At 3rd week start the checks distributed randomly to 4 treatments of 2 replicate each of 20 chicks. the control treatment fed standard ration and water ad libitum for 23 hours during the experiment period. while treatments 2,3,4 ware fed 6,9,12 hours daily respectively during the 3,4 week of age, While these feeding during the late period in 5,6 week of age in the treatments 5,6,7 . the result showed insignificant difference between early and late period for find body weight and total mortality also there was no significant difference within restriction level in final body weight, there was significant decrease in total mortality at 9,12 hour compared to free and 6 hour treatment, there was no significant difference in interaction effect between restriction level and period in final body weight. there was significant decrease in treatments 4,5,6,7 in total mortality compared to treatments 2,3 . There was no significant decrease in total body weight gain and feed conversion ratio in the effect of restriction period and level and interaction between them, but there was significant decrease within the period effect in feed consumption during the late period compared to early period, within restriction effect and interaction between period and restriction level there was significant decrease in feed consumption. For all restriction levels and treatments compared to control. There was significant decrease within period effect between early and late restriction in carcass weight its parts edible giblets, abdominal fat, dressing percentage, in the effect of time restriction level there was significant increase in percentage of breast meat in 9 hour level compared to other levels . There was significant difference in percentage abdominal fat for 6,9 hour treatments compared to other levels, There was no significant difference in dressing percentage between 9,12 hour and control , While there was significant difference in dressing percentage for 6 hour treatment compared to other treatments, There was on significant difference in interaction effect between period and level of restriction in carcass weight and its parts , edible giblets , abdominal fat between all treatments. There was no significant difference in dressing percentage between all treatments compared to control treatment except 6 hours treatment which decreased from control.
