The effect of feed restriction during the rearing Period on the reproductive Performance was studied using 400 birds of dual purpose breeder pullet (Rhode Island Reds). During the rearing period (7∼21 week of age) feed was affered 80%, 70%, 60% of feed consumption of full feed group, All groups were full feed during laying period after 21 week of age. The results abtained are summarized as follows ; 1. Viability was not significantly affected by the feed restriction in either the rearing period or laying period of the experiment. 2. Body weight of 60% restricted group at 22 weeks of age was 75% of control group. At 72 weeks of age it was 95% of that of full feed group and not yet recovered completely. 3. Feed consumption of restricted groups from 22 to 72 weeks of age was some what more than that of control group, but total feed consumption per hen of all age was significantly different according to the feed restriction. 4. The degree of sexual maturity as measured by age at 50% egg Production was delayed from 9 to 27 days compared to control group according to the restricted intensity during rearing period. 5. Hen-day egg production (22-72 weeks of age) was range from 67.23 to 68.79% among treatment. There was not significant difference among treatment. 6. Average hen-housed egg production over 53g per bird to the end of the experiment was 154.2 eggs for control and 159.7 eggs for 80%, 157.4 eggs for 70%, 166.9 eggs for 60% restricted group. There was significant difference at 5 % level among treatment. 7. Average egg weight was significantly increased in restricted groups relative to control. The difference between restricted groups and control was highly significant average egg weight. 8. In the economic analysis, feed cost for 1 hatchable egg (over 53g) was in the highest with the control group and was decreased as the degree of feed restricted intensity. On the basis of the results of this study, it was suggested that in dual purpose breeder the feed restriction should be fed 60% of control group during the rearing period (7-21 weeks of age) and the body weight at 22 weeks of age should be kept at the level of 75 of the control in other to get better performance during the laying period.
