The effect of variable feed restriction and dietary protein in terms of egg production was estimated as four weekly period basis for five periods from 25-44 weeks age on 192 dwarf broiler breeder dams. The periods were denoted as period I, II, III, IV, V. Four feed restriction considered were 0 (A 0), 10 (A 1), 20 (A 2) and 30% (A 3) and four dietary protein levels were 16 (B 0), 17 (B 1), 18 (B 2) and 19 (B 3). The birds of all groups were fed with isocaloric energy i.e. 2700 kcal ME/ kg diet throughout the experimental period. Highly significant feed restriction and dietary protein effects were obtained for number of eggs produced and percent egg production of dwarf broiler dams in all five periods and on overall basis. The overall number of eggs recorded were 88.7, 91.4, 83.9 and 79.6 and percent egg production was 60.3, 62.3, 57.1 and 54.1, respectively for A 0, A 1, A 2 and A 3 feed restriction groups. As the age advanced number of eggs also increased and this was true for all restriction levels. Birds fed 10% less feed laid more number and percent of eggs in comparison to other groups. When feed was restricted more than 10% the egg production get reduced. On overall basis means observed for egg number was 82.8, 84.9, 87.0 and 88.9 and percent egg production was 56.3, 57.8, 59.2 and 60.5, respectively for B 0, B 1, B 2 and B 3 group. From the study it can be concluded that 10% feed restriction and 19% protein level are best for egg number and percent egg production of dwarf broiler hens.
