Effects of Dietary Supplementation With Saccharomyces cerevisiae Yeast Extract on Production Performance in Aged Commercial Laying Hens. [PDF]

Vet Med Sci
Saccharomyces cerevisiae yeast extract in the diet of laying hens did not have a significant effect on productive performance indicators. This extract increased the thickness and relative weight of eggshell. ABSTRACT Background Broken‐shell eggs in aged laying hens cause great losses to the egg industry. Saccharomyces cerevisiae yeast may improve shell

Dietary supplementation with sodium bicarbonate or sodium sulfate affects eggshell quality by altering ultrastructure and components in laying hens

Animal, 2021
Dietary sodium (Na) levels were related to the content of the eggshell matrix. We therefore speculated that dietary Na supplementation as sodium bicarbonate (NaHCO3) or sodium sulfate (Na2SO4) may improve eggshell quality. Additionally, dietary NaHCO3 or

The fracture toughness of eggshell [PDF]

Acta Biomaterialia, 2016
The shells of avian eggs are very brittle, but how brittle? Fracture toughness, Kc is a standard measure used widely to characterise engineering materials. We devised a novel way to measure Kc and applied it to commercial hens' eggs, obtaining a value of 0.3MPa√m. This value is much lower than previous published values, which we argue are incorrect and

The Effects of Intrauterine Injection with Prostaglandin F2α, Arachidonic Acid and Phosphate Solution on the Eggshell Formation of Japanese Quail Hen

The Journal of Poultry Science, 2002
Inhibitory effects of prostaglandin F2α, arachidonic acid and phosphate solution on the eggshell formation were investigated in Japanese quail. All injections were performed intrauterinely 8h before the predicted oviposition. Prematurely oviposited

The Evolution of Functional Amyloids and Their Impact on Host–Microbe Interactions

Advanced Science, EarlyView.
This review describes functional amyloids and highlights the importance of structural repetition and molecular mimicry that distinguish the amyloid fold. The authors describe how amyloid can be the last universal common ancestor of protein folds. The authors also discuss how microbes utilize functional amyloids and how the structural characteristics of

The Effects of Egg Shape Index on Egg Quality Traits of Guinea Fowl (Numida meleagris)

Turkish Journal of Agriculture: Food Science and Technology, 2016
The aim of this study was to investigated the effects of the egg shape index on egg quality characteristics in Guinea fowl. For this, the eggs were classified in terms of egg shape index, as ≤ 75, < 76 -77 > and ≥ 78. A total of 100 Guinea fowl eggs were

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

The Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.
