Leptin receptor in the chicken ovary: potential involvement in ovarian dysfunction of ad libitum-fed broiler breeder hens [PDF]
, 2004 In hens, the ovarian follicles committed to ovulation are arranged in an ordered follicular hierarchy. In standard broiler breeders hens genetically selected for high growth rate the reproductive function is clearly dysfunctional.

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 ...
