In a normal broiler breeder flock, rate of lay peaks early and then gradually declines and egg quality drops through thinning of the shell and reduced albumen quality. In an investigation of the effects of 3 female broiler breeder target BW profiles on reproductive traits, the impact of increased or decreased target BW profile on subsequent egg composition and quality attributes was investigated. A total of 216 Ross 708 pullets were reared in floor pens. Birds were individually caged at 16 wk and assigned to a BW profile: STD (Standard BW control), HIGH or LOW (10% higher or lower BW than STD, respectively). Following peak feed at 30 wk, feed declined 3.3 (HIGH), 2.5 (STD) or 2 (LOW) g/wk, on average, until 43 wk of age. Feed then increased 1g/wk, on average, to 50 wk of age. Individual egg production records were kept, and egg composition and quality (% shell, shell thickness, albumen height, specific gravity) determined at 5 wk intervals from 30 wk of age.
