2001 journal article

Effects of Incubational Humidity and Hen Age on Embryo Composition in Broiler Hatching Eggs from Young Breeders ,

Poultry Science, 80(9), 1299–1304.

By: E. Peebles*, M. Burnham*, C. Gardner*, J. Brake n, J. Bruzual n & P. Gerard*

author keywords: broiler breeder; embryo; incubation; relative humidity
MeSH headings : Age Factors; Animals; Body Composition; Body Weight; Breeding / methods; Chick Embryo / chemistry; Chick Embryo / growth & development; Chickens / physiology; Female; Humidity; Incubators; Male; Time Factors
TL;DR: It was demonstrated that broiler breeder age affects embryogenesis and hatching chick BW and changes in incubational RH between 43 and 63% affected embryogenesis without having associated effects on EM or consistent effects on embryo crude fat and protein content. (via Semantic Scholar)

2001 journal article

Effects of Incubator Humidity and Hen Age on Yolk Composition in Broiler Hatching Eggs from Young Breeders

Poultry Science, 80(10), 1444–1450.

By: M. Burnham*, E. Peebles*, C. Gardner*, J. Brake n, J. Bruzual n & P. Gerard*

author keywords: broiler breeder; embryo; incubation; relative humidity
MeSH headings : Age Factors; Animals; Body Composition; Breeding; Chick Embryo / growth & development; Chick Embryo / physiology; Chickens; Egg Yolk / chemistry; Humidity; Incubators / veterinary; Lipids / analysis; Yolk Sac / physiology
TL;DR: Rate of yolk uptake from the yolk sac by embryos may be increased by incubating eggs at 53% RH, and the effects of changes in RH between 43 and 63% on yolk lipid content are influenced by breeder age. (via Semantic Scholar)

Albumen height and yolk and embryo compositions in broiler hatching eggs during incubation

Poultry Science, 79(10), 1373–1377.

By: E. Peebles*, C. Gardner*, J. Brake n, C. Benton n, J. Bruzual n & P. Gerard*

author keywords: albumen height; broiler breeders; embryo; incubation; yolk
MeSH headings : Animals; Chick Embryo / anatomy & histology; Chick Embryo / chemistry; Chickens; Egg White; Egg Yolk / chemistry; Fatty Acids / analysis; Female; Lipids / analysis; Male; Ovalbumin / physiology; Proteins / analysis; Time Factors; Water
TL;DR: Differences in yolk fatty acid profiles between AH groups during early incubation may impact subsequent embryo DM weight without associated effects on embryo moisture, protein, or lipid contents. (via Semantic Scholar)

2000 journal article

Effects of relative humidity during the last five days of incubation and brooding temperature on performance of broiler chicks from young broiler breeders

Poultry Science, 79(10), 1385–1391.

By: J. Bruzual n, S. Peak n, J. Brake n & E. Peebles*

author keywords: hatchability; embryo mortality; incubation; young broiler breeders; brooding
MeSH headings : Animals; Chick Embryo / physiology; Chickens / growth & development; Chickens / physiology; Female; Humidity; Male; Temperature; Time Factors; Weight Gain
TL;DR: Chick quality problems that may be due to high or low RH during incubation can be ameliorated by proper brooding conditions, and optimal chick performance was achieved at 53% RH. (via Semantic Scholar)
