Efficacy of three sealing methods on hatchability of micro-cracked eggs from broiler breeder hens

open access: yesRevista Colombiana de Ciencias Pecuarias, 2018
Background: Shell fragility of hatching eggs can have negative implications on the economic performance of hatcheries. Objective: To determine the efficacy of sealing eggshell micro cracks with either coloured or uncoloured nail varnish, and molten ...

A Novel Shell-less Culture System for Chick Embryos Using a Plastic Film as Culture Vessels

open access: yesThe Journal of Poultry Science, 2014
The development of shell-less culture methods for bird embryos with high hatchability would be useful for the efficient generation of transgenic chickens, embryo manipulations, tissue engineering, and basic studies in regenerative medicine.

Research Note: Effects of turning and short period of incubation during long-term egg storage on embryonic development and hatchability of eggs from young and old broiler grandparent flocks1

open access: yesPoultry Science, 2021
Longer egg storage times (>7 d) are common in broiler parent and grandparent hatcheries to obtain the requested flock size. However, prolonged storage is known to decrease hatchability.

Influence of Oxygen Concentration on Hatchability and on Selecting for Hatchability , ,

open access: yesPoultry Science, 1955
Abstract OBTAINING a respectable hatching percentage from the eggs of domestic poultry is one of the important problems of the poultry industry in areas of high elevation. This problem exists at Laramie, Wyoming, where the elevation is approximately 7,200 feet above sea level. The Wyoming Agricultural Experiment Station, highest in the United States,

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Effects of maternal nutrition on hatchability

open access: yesPoultry Science, 1997
The effects of dietary factors on the development and viability of avian embryos have been extensively documented. A good nutritional status of the parent birds is crucial to the transfer to the egg of an adequate, balanced supply of nutrients required for normal development of the embryo.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
