Developmental Characteristics of the Embryonic Liver Tissue and Long‐Term Culture of Primary Hepatocytes in Duck

Animal Research and One Health, EarlyView.
Liver development was investigated at different embryonic ages (EAs). Furthermore, numerous hepatocyte media were formulated and evaluated. These results could elaborate the developmental characteristics of duck liver tissue and determine the most suitable medium for the proliferation and characteristic maintenance of hepatocytes in vitro, which would ...

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

An Evaluation of the AOAC Method of Yolk Color Analysis

Poultry Science, 1980
Abstract Experiments were conducted to evaluate and compare several methods of egg yolk color analysis. Egg yolks of various colors and intensities were produced either by feeding known concentrations of synthetic xanthophylls to color depleted hens or by mixing the xanthophylls directly into depleted egg yolks.

Effect of Vitamin E, Lutein, Selenium and Oil Mixture Added to Feed and Cooking Length on Yolk Color and Egg Quality [PDF]

, 2015
The aim of this research was to determine the quality of eggs laid by Tetra SL hens fed standard diet (B) or diet supplemented with 100 mg vitamin E/kg+200 mg/kg lutein+0.5 mg/kg selenium+5% oil mixture (BK).

Silky Fowl (Gallus gallus domesticus) Dietary Supplementation with Dried Red Pepper (Capsicum annuum): Effects on Egg Quality, Blood Biochemical Parameters, and Egg Storage Stability

Poultry
Egg yolk coloration influences consumer perceptions of table eggs. Red pepper (Capsicum annuum) is a known dietary source of carotenoids, which enhances yolk pigmentation, but its effects in silky fowl (SF) remain unexplored.

The Effect of Seaweed Carotenoids on Egg Yolk Coloration

Poultry Science, 1963
Abstract CONTRADICTORY records are found in the literature on the effect upon egg yolk coloration of feeding seaweed meal to the laying hen. While Olsson (1941) and Black (1953) observed little or no effect, Hoie and Sannan (1960) found a significant darkening of the egg yolk on addition of 5 percent of seaweed meal to the rations.

The Effect on Yolk Color of Various Ingredients in Poultry Feeds

Poultry Science, 1937
Abstract VARIATIONS in egg yolk color are of economic importance to the commercial poultryman. Because of rigid egg grading and candling practices, there is a demand for eggs with uniform-colored yolks for discriminating markets. This, together with the occasional necessity for the poultryman to vary his laying ration, makes it desirable that he know

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...
