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

Cardiac morphological and morphometric analysis of Ardea alba
The 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 ...

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

The 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).

Animal 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.

Determination of Keratinase Activity using Chicken Feather DMSO extract and its optimization with Response Surface Methodology [PDF]
E3S Web of ConferencesKeratinase is an enzyme capable of degrading keratin, exhibiting two activities: protease activity, which cleaves peptide bonds, and disulfide reductase activity, which reduces disulfide bonds (-S-S-). However, keratinase activity is often measured using
