Effects of supplementing natural astaxanthin from Haematococcus pluvialis to laying hens on egg quality during storage at 4°C and 25°C

Poultry Science, 2020
The objective of this study was to evaluate the effects of different levels of dietary natural astaxanthin (ASTA) (from the microalga Haematococcus pluvialis) and storage at 4°C and 25°C on the quality of eggs from laying hens. Nongda No.

Yolk Color Characteristics, Xanthophyll Availability, and a Model System for Predicting Egg Yolk Color Using Beta-Apo-8′-Carotenal and Canthaxanthin

Poultry Science, 1978
Abstract The egg yolk pigmenting ability of beta-apo-8′-carotenaI and canthaxanthin was evaluated using reflectance colorimetry to both describe the color and determine relative biological availability. Laying hens, previously depleted of xanthophylls, were fed diets containing 0, 2.2, 4.4, 8.8, and 17.6 mg/kg, of each of the two xanthophylls, in a 5

Effects on egg yolk colour of paprika or paprika combined with marigold flower extract

Italian Journal of Animal Science, 2010
COLOR-UP® and COLOR-UP YELLOW-S® were fed to a total of 144 twenty-five-week-old Charoen Pokphand brown laying hens to investigate whether yellow xanthophylls present in marigold flowers in combination with red xanthophylls from paprika fruit can

Development and Use of Color Standards for Egg Yolks

Poultry Science, 1962
Abstract FOR SOME YEARS poultry scientists have been engaged in nutrition studies on the effects of various grains fed to laying birds. Some of these studies have been concerned with the effect of grain or combinations of grains in determining yolk color.

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

Advanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

The Quality of Chicken Eggs Fed Black Pepper (Piper nigrum L.) Flour [PDF]

BIO Web of Conferences
The objectives of this study were to analyze the quality of laying hen eggs fed with feed containing black pepper (Piper nigrum L) flour. A total of 200 brown laying hens strain MB 402 (50 weeks-old) were used in this experiment. The research design used

Organ‐Specific and Conserved Regulatory Logic Orchestrates Gene Expression in the Embryonic Mesothelium

Advanced Science, EarlyView.
Integrated multi‐omic profiling maps the gene‐regulatory landscape of the coelomic mesothelium across heart, lung, and pancreas. A cardiac‐restricted regulatory program is uncovered in which TBX20 activates heart mesothelial (epicardial) cis‐regulatory elements, while MAF emerges as a conserved regulator of mesothelial identity.

The Influence of Yolk Color Intensity Upon Yolk Shadow Values, Albumen Quality and Yolk Color Index — Deposition and Color Intensity of Abdominal Fat of Pullet Carcasses

Poultry Science, 1961
Abstract INTRODUCTION IN ALL sections of the country shell eggs are being produced under different, effective feeding and management programs. These programs contribute to the development of egg yolks that vary considerably in color intensity.

Dietary marine algae maintains egg consumer acceptability while enhancing yolk color

Poultry Science, 1998
A drum-dried docosahexaenoic acid (DHA; C22:6n-3) enriched marine microalgal product (MA) was investigated as a n-3 fatty acid (n-3 FA) source in laying hen diets. Hen diets were supplemented with 2.4 or 4.8% MA. Eggs were analyzed for yolk color following 4 wk of feeding as well as weekly for 4 wk.

Extracellular Vesicle‐Transferred ATP‐Citrate Lyase Induces Monocyte Differentiation Toward Tumor‐Associated Macrophages and Fuels Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Hepatocellular carcinoma (HCC)‐derived extracellular vesicles (EVs) enrich the metabolic enzyme ATP‐citrate lyase (ACLY). EV‐transferred ACLY enhances palmitate biosynthesis, increases the S‐palmitoylation and stability of multiple immune checkpoint proteins, augments the cellular immunosuppressive activity, and ultimately accelerates the malignant ...
