Effects of Different Fertility Rates on Chick Quality and Hatching Parameters in Hatching Eggs

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2014
This study was conducted to investigate the hatching parameters differences between the hatching eggs which were controlled or not for fertility at 18th day of embryo development in the hatchery unit.

Results of hatching and rearing broiler chickens in different incubation systems

open access: yesPoultry Science, 2021
Hatchery efficiency is based on hatchability and the number of salable chicks. The hatchery sector has been seeking new alternatives to optimize production rates, including the use of different systems (multistage [MS] or single-stage [SS] machines) to ...

Vital dye labelling demonstrates a sacral neural crest contribution to the enteric nervous system of chick and mouse embryos [PDF]

open access: yes, 1991
We have used the vital dye, DiI, to analyze the contribution of sacral neural crest cells to the enteric nervous system in chick and mouse embryos. In order to label premigratory sacral neural crest cells selectively, DiI was injected into the lumen of ...

Insulin Hypoglycemia in Chick Embryos.

open access: yesExperimental Biology and Medicine, 1948
Landauer1, 2 has found that certain morphological abnormalities may be produced by injecting insulin into the yolk of 0-5-day chick embryos. In the course of an investigation into the carbohydrate metabolism of insulin-treated embryos we have found that a persistent hypoglycemia is produced by insulin applied in this manner.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

A new oxidative stress model, 2,2-azobis(2-amidinopropane) dihydrochloride induces cardiovascular damages in chicken embryo. [PDF]

open access: yesPLoS ONE, 2013
It is now well established that the developing embryo is very sensitive to oxidative stress, which is a contributing factor to pregnancy-related disorders.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Neural tube-ectoderm interactions are required for trigeminal placode formation [PDF]

open access: yes, 1997
Cranial sensory ganglia in vertebrates develop from the ectodermal placodes, the neural crest, or both. Although much is known about the neural crest contribution to cranial ganglia, relatively little is known about how placode cells form, invaginate and

Expression of avian prickle genes during early development and organogenesis [PDF]

open access: yes, 2008
Chicken homologues of prickle-1 (pk-1) and prickle-2 (pk-2) were isolated to gain insight into the extent of planar cell polarity signaling during avian embryogenesis.

Histopathologic Analysis of the Morpho‐Functional Zones of the Human Acetabular Labrum

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The structural and functional adaptation of soft tissues to mechanical load controls their ability to withstand injury and influences their capacity for healing. Similar to the knee meniscus, the acetabular labrum exhibits zonal differences in mechanical load distribution, resulting in distinct regions with unique structural and functional ...
