The impact of eggshell colour and spot area in Japanese quails: I. eggshell temperature during incubation and hatching results [PDF]

open access: yesRevista Brasileira de Zootecnia, 2016
This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica).

TAPHONOMIC EFFECTS OF HIGH TEMPERATURE ON AVIAN EGGSHELL

open access: yesPalaios, 2011
Abstract The taphonomic effects of heat and or fire on bones, conodonts, and plant tissues have received much attention from paleontologists and geologists, but the effect of high temperatures on amniote eggshell has been unknown.

Taphonomic Effects of pH and Temperature on Extant Avian Dinosaur Eggshell

open access: yesPALAIOS, 2004
Abstract Avian and non-avian dinosaur eggshell contains clues that are helpful in the reconstruction of ancient habitats and behaviors. Fossilized eggshell often shows signs of corrosion attributed to acid dissolution of the calcium carbonate, but this process has never been quantified in controlled experiments.

Amino acid racemization dating: Method development using African ostrich (Struthio camelus) eggshell [PDF]

open access: yes, 2013
Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis.

Effect of Sintering Temperature on the Morphology and Adhesion Strength of Eggshell Coating on Mild Steel

open access: yesSolid State Phenomena, 2017
Eggshell waste is rich source of calcium carbonate and can be applied to protect steel pipe from corrosion. Calcium carbonate precipitation can be naturally formed as a coating to protect steel pipe from oxygen diffusion. However, with calcium carbonate formed due to natural process, it is difficult to achieve the adequate thickness and capable of ...

Effects of late incubation temperature and moment of first post-hatch feed access on neonatal broiler development, temperature preference, and stress response

open access: yesPoultry Science, 2022
: Early life experiences are known to be of great importance for later life. For instance, exposure to stress during early life can increase fearfulness at later age. In broilers, delayed feeding after hatch may cause metabolic stress.

Broiler resilience to colibacillosis is affected by incubation temperature and post-hatch feeding strategy

open access: yesPoultry Science, 2022
: Colibacillosis is a poultry disease that negatively affects welfare and causes economic losses. Treatment with antibiotics raises concerns on antimicrobial resistance.
