Internal and external bacterial counts from shells of eggs washed in a commercial-type processor at various wash-water temperatures
JOURNAL OF FOOD PROTECTION, 60(11), 1324–1328.
author keywords: eggs; bacteria on eggshell; wash water temperature; egg washing
TL;DR:
On the basis of the data, spray washing eggs in l5.5°C water does not appear to increase internal shell bacterial counts, and a reexamination of cold-water processing procedures may be in order.

Cryogenic Gas for Rapid Cooling of Commercially Processed Shell Eggs Before Packaging
Journal of Food Protection, 58(4), 389–394.
author keywords: SHELL EGGS; RAPID COOLING
TL;DR:
The results of this trial suggest that rapid cooling with cryogenic gases could be used in conjunction with current commercial egg processing to cool eggs prior to packaging to reduce egg temperatures as well as the likelihood of Salmonella enteritidis growth in or on eggs.

Duodenal Calcium Uptake, Femur Ash, and Eggshell Quality Decline with Age and Increase Following Molt
Poultry Science, 73(10), 1590–1596.
author keywords: LAYING HEN; INTESTINAL CALCIUM UPTAKE; FEMUR ASH; SHELL QUALITY; MOLT
MeSH headings : Age Factors; Animals; Bone Density; Calcium / metabolism; Chickens / physiology; Egg Shell / anatomy & histology; Feathers / physiology; Female; Femur / physiology; Intestinal Absorption
TL;DR:
An experiment was conducted to test the hypothesis that the decline in eggshell quality over time during egg production, and its improvement after molting, paralleled the rate of calcium uptake by the duodenum of the laying hen.

Effects of Cage Versus Floor Rearing Environments and Cage Floor Mesh Size on Bone Strength, Fearfulness, and Production of Single Comb White Leghorn Hens ,
Poultry Science, 73(8), 1233–1240.

MeSH headings : Animal Husbandry; Animals; Behavior, Animal; Body Weight; Bone and Bones / anatomy & histology; Bone and Bones / physiology; Chickens / physiology; Fear; Female; Oviposition / physiology; Population Density
TL;DR:
Hens reared in cages produced heavier eggs with a higher percentage of Grade A eggs and had fewer body checks than floor-reared birds and Alteration of the mesh size of layer cage floor had no effect on the production levels of the hens.

Mycotoxins and Feed Refusal by Pekin Ducks
Journal of Applied Poultry Research, 3(2), 190–192.
TL;DR:
Pathological analysis indicated that the ducklings were dehydrated with no feed in the gastrointestinal tract, and a necropsy diagnosis indicated a condition similar to starve-outs and feed refusal.

Effects of Rearing Density and Feeder and Waterer Spaces on the Productivity and Fearful Behavior of Layers
Poultry Science, 71(1), 53–58.

TL;DR:
Two groups of White Leghorn pullets reared in cages were used to study the effects of rearing density and feeder and waterer spaces on their performance and fearful behavior, and the results confirmed that rearing at a density of 193 versus 221 cm2 had lower outcomes.
