The Relationship of Eggshell Structure to Eggshell Penetration by 'Salmonella' Typhimurium in Table Eggs

open access: yes, 2018
This project sought to correlate external shell features with underlying shell structures and examine if these structures are indicative of increased incidence of eggshell penetration by Salmonella Typhimurium.

Eggshell uniformity and the relationship between shell structures and shell translucency, examined by Computated Tomography (CT) and Scanning Electron Microscopy (SEM)

open access: yes, 2016
While it has been determined that eggshell translucency is caused by the accumulation of moisture within the structures of the shell, it is still unclear precisely which shell structures are related to translucency.

Influence of egg shell translucency on egg shell penetration by bacteria

open access: yes, 2012
Egg shell translucency, which can be due to changes in the mammillary cores and mamillary layer during the early phases of eggshell formation, has the potential to increase the incidence of microcracks in egg shells, and hence, may facilitate bacterial ...

SEM (Scanning electron microscopy) assessment of eggshell quality after gas plasma decontamination treatments

open access: yes, 2009
Gas plasma treatment of whole egg represents an innovative decontamination technique for the eggshell surface. However, it is not clear if the treatment can damage the natural defence of the egg such as cuticle and shell membranes.

The Effect of Dietary Supplementation with Calcium Pidolate and 25-Hydroxycholecal Ciferol on Egg Quality in Commercial Laying Hens

open access: yes, 2017
Seven groups from a total of 147 Lohmann Brown laying hens were housed individually in cages from 21 to 80 weeks of age. Birds were divided into a control group and groups receiving layer mash formulated to commercial standards supplemented with either a

Effect of 25-hydroxycholecalciferol supplementation on egg quality, body weight and feed intake in commercial laying hens

open access: yes, 2016
HyLine Brown layer hens from 19 to 50 weeks of age were used to determine the effects of supplemental 25-hydroxycholecalciferol (25(OH)D₃) on egg internal quality, eggshell quality, amount of cuticle present on the eggshells, body weight, and feed intake.

Evaluating the use of translucency score as an effective parameter of eggshell quality

open access: yes
The objective of this thesis was to determine if an egg’s translucency score (TS) could be used as an effective predicting parameter to determine eggshell quality in both broiler breeders and commercial laying hens. In broiler breeders, it was determined
