Water Usage of Broiler Breeders
Poultry Science, 1989 Water usage of daily fed and skip-a-day-fed broiler pullets housed in cages was measured in two trials. Daily fed birds in both trials had free access to water. In Trial 1, skip-a-day-fed birds were restricted to 4 h water every day or only on feed days. In Trial 2, the skip-a-day-fed birds were water restricted 4 h either every day, only on feed days,

Sodium Chloride for Broiler Breeders
Poultry Science, 1983 Two experiments, each of 224 days duration, were conducted with Cobb broiler breeders, 32 weeks of age, to determine their response to supplemental dietary sodium chloride levels ranging from .12 to .48% in a corn-soybean meal diet. Average hen-day egg production, daily feed intake, feed required per dozen eggs, and egg specific gravity were not ...

Targeted differential monochromatic lighting improves broiler breeder reproductive performance
Poultry Science, 2020 Light perception in birds is composed of the retina and extraretinal sites, located in the brain. Previous studies indicate that selective photostimulation of the eye decreased reproductive performance, whereas extraretinal photostimulation increases it.

Restricted Feeding of Broiler Breeders
Poultry Science, 1983 Two experiments were conducted to compare the effects of various feed restriction programs during the growing and laying periods on body weight, egg production, fertility, and hatchability. In the first experiment, Cobb color-sexed broiler breeders were fed one of three grower programs (full feed, skip-a-day, or low protein) from 8 to 24 weeks of age ...

Broiler breeder paradox: a project report [PDF]
World's Poultry Science Journal, 2006 A first product of this European project was a tool for scoring chick quality. A link was established between chick quality and embryonic physiological parameters such as heat production. Eggs from broiler breeders that give rise to rapidly growing broilers have a different embryonic development that may need modified incubation conditions.
