Understanding the spacing of placodes in the eye: A comparative study across age and species

open access: yesThe Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Specific mutations in the genes of MC1R and TYR have an important influence on the determination of pheomelanin pigmentation in Korean native chickens

open access: yesJournal of Advanced Veterinary and Animal Research, 2021
Objective: The TYR (Tyrosinase) and MC1R (Melanocortin 1 receptor) genes are recognized as important genes involved in plumage pigmentation in Korean native chickens. Specifically, most color patterns in chicken result from differential expression of the

A Question on the Locations of the Tardy Feathering and Henny Feathering Loci in the Chicken

open access: yesPoultry Science, 1994
The locus for tardy feathering (t), previously mapped to the long (q) arm of chromosome 1 of the chicken, was tested for genetic linkage with both the NM 7659 t(Z;1) rearrangement break point (RB) and the henny feathering (Hf) locus. The RB is proximal to the centromere on 1q, and Hf has been reported to be on the proximal one-third of the same arm ...

Cardiac morphological and morphometric analysis of Ardea alba

open access: yesThe Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

open access: yesThe Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Adsorption isotherm and kinetics for the removal of nitrate from wastewater using chicken feather fiber

open access: yesCogent Engineering, 2022
Nitrate has been identified as a major source of water pollution and eutrophication. The use of modified chicken feathers (MCFs) as an adsorbent has not been fully explored.

DNA Isolation of Chicken Feathers from the Base of the Young Feathers, the Base of the Old Feathers, and the Tip of the Feathers

open access: yesBIOEDUSCIENCE, 2021
Background:  The goal was to provide information on the use of DNA templates in chicken samples so that the molecular research sampling process may employ feathers instead of hurting the test animals. Method: The sample used consisted of 10 Bangkok chickens which were sampled for young feathers and old feathers and the tips of the feathers ...

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.
