2009 journal article

The effects of oviposition time on egg weight loss during storage and incubation, fertility, and hatchability of broiler hatching eggs

Poultry Science, 88(12), 2712–2717.

By: A. Zakaria*, P. Plumstead n, H. Romero-Sanchez*, N. Leksrisompong n & J. Brake n

author keywords: oviposition time; egg storage; broiler breeder; egg weight loss; hatchability
MeSH headings : Animals; Chickens / physiology; Female; Fertility; Male; Oviposition / physiology; Ovum / physiology; Time Factors
TL;DR: It was concluded that there was no effect of oviposition time on fertility or fertile hatchability even though there were significant differences in egg weight and egg weight loss during storage due to ovipposition time. (via Semantic Scholar)

2008 journal article

Feeding Broiler Breeder Males. 4. Deficient Feed Allocation Reduces Fertility and Broiler Progeny Body Weight

Poultry Science, 87(4), 805–811.

By: H. Romero-Sanchez*, P. Plumstead n, N. Leksrisompong n, K. Brannan n & J. Brake n

author keywords: broiler breeder male; rearing nutrition; fertility; broiler performance
MeSH headings : Animal Nutritional Physiological Phenomena; Animals; Body Weight / physiology; Chickens / physiology; Eating / physiology; Energy Metabolism; Female; Fertility / physiology; Male; Nutritional Status / physiology
TL;DR: Adequate breeder male feed allocation during the production period improved fertility and favorably affected broiler progeny performance in both experiments, which suggests that the males with the greatest genetic potential were not mating at these times. (via Semantic Scholar)

2007 journal article

Effects of Phosphorus Level and Phytase in Broiler Breeder Rearing and Laying Diets on Live Performance and Phosphorus Excretion

Poultry Science, 86(2), 225–231.

By: P. Plumstead n, H. Romero-Sanchez*, R. Maguire *, A. Gernat* & J. Brake n

author keywords: broiler breeder; phosphorus; phytase; environment; litter
MeSH headings : 6-Phytase / pharmacology; Animal Feed; Animal Nutritional Physiological Phenomena; Animals; Biological Availability; Chickens / growth & development; Diet / veterinary; Dietary Supplements; Feces / chemistry; Female; Male; Oviposition / drug effects; Phosphorus / analysis; Phosphorus / metabolism; Phosphorus / pharmacology; Weight Gain / drug effects
TL;DR: Results showed that phytase inclusion in a broiler breeder laying diet at the expense of all added P from dicalcium phosphate reduced the manure total P and WSP concentrations by 42%, with no effect on the number of chicks produced per hen housed. (via Semantic Scholar)

2007 journal article

Feeding Broiler Breeder Males. 3. Effect of Feed Allocation Program From Sixteen to Twenty-Six Weeks and Subsequent Feed Increments During the Production Period on Body Weight and Fertility

Poultry Science, 86(4), 775–781.

By: H. Romero-Sanchez*, P. Plumstead n & J. Brake n

author keywords: broiler breeder; feeding program; fertility; body weight
MeSH headings : Animal Feed; Animals; Body Weight / physiology; Chickens / growth & development; Diet; Energy Intake; Fertility; Male; Weight Gain / physiology
TL;DR: Two experiments were conducted to compare different feed allocation programs from 16 to 26 wk of age and during the subsequent production period on broiler breeder male BW and fertility and found increasing male feed allocation during the production period improved fertility.

2005 journal article

Oviposition pattern, egg weight, fertility, and hatchability of young and old broiler breeders

Poultry Science, 84(9), 1505–1509.

By: A. Zakaria*, P. Plumstead n, H. Romero-Sanchez n, N. Leksrisompong n, J. Osborne n & J. Brake n

author keywords: broiler breeder; egg sequence; oviposition time; fertility; hatchability
MeSH headings : Aging; Animals; Chick Embryo / physiology; Chickens / physiology; Egg White; Female; Fertility; Male; Oviposition; Ovum / physiology; Reproduction; Time Factors
TL;DR: Although there were differences in egg weight among eggs at different times of the day (different sequence positions), there were no differences in fertility, fertile hatchability, or embryonic mortality in naturally mated broiler breeders. (via Semantic Scholar)
