What is Body Composition, Gastrointestinal, and Reproductive Differences Between Broiler Breeders Fed Using Everyday or Skip-a-day Rearing Programs about?
Broiler breeder feed restriction practices have intensified as broiler feed efficiency has been improved. Skip-a-day (**SAD**) rearing regimen has controlled breeder growth, although this practice has become questionable for the modern breeder. We compared everyday (**ED**) and SAD programs and evaluated their impact on pullet growth performance, body composition, gastrointestinal tract development, and reproduction. At d 0, Ross 708 (Aviagen) pullet chicks (__n__ = 1,778) were randomly assigned to 7 floor pens. Three pens were fed using the ED and 4 pens with SAD program through wk 21 using a chain-feeder system. ED and SAD grower diets were formulated to be isonutritious, with the only difference that ED diets had more crude fiber. Pullets (__n__ = 44 per pen) were moved to 16 hen pens by treatment at wk 21 with 3 YP males (Aviagen) in each pen. All birds were fed common laying diets. In addition to BW data, sampled pullets and hens were scanned using dual energy X-ray absorptiometry (**DEXA**) to obtain body bone density and composition. Hen performance and hatchery metrics were recorded through wk 60. ED birds were heavier with similar nutrient intake from wk 10 to 45 (__P__ ≤
