Measurement of Egg Yolk Color by Means of the Colorimeter

Poultry Science, 1949
Abstract THE color of the yolk of egg has received considerable attention for it is known to affect the desirability of the egg. A yolk that is either too highly colored or too pale is objectionable. Palmer (1915) (1919) reported that specific feeds affected the color of the egg yolk and that the color was due almost entirely to the pigment ...

Effects of different concentrations of canthaxanthin microencapsulated with gelatin or lignosulfonate on laying performance, yolk color of hens

Italian Journal of Animal Science
Gelatine (GL) is widely available as a microencapsulated material that prevents the decomposition of canthaxanthin (CX). However, there are still disadvantages such as instability, poor safety, and chromium overload.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
