Ontogenetic development of tetra Astyanax lacustris (Characiformes: Characidae)

open access: yesNeotropical Ichthyology, 2018
Ontogenetic development of the tetra Astyanax lacustris was studied under laboratory conditions. Larvae obtained by induced reproduction were maintained individually in tissue-culture plates, at 25°C. Daily observations and morphometric measurements were

A comprehensive embryonic staging series of the turtle Trachemys scripta. [PDF]

open access: yesDev Dyn
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Effect of 3-Nitro-10 on Egg Yolk Pigmentation

open access: yesPoultry Science, 1982
White Leghorn hens, housed in cages were fed commercial-type corn-soy diets containing one of three levels of 3-Nitro-10 (0, .0025, and .005%) and either of two levels of xanthophyll (high and low) supplied by yellow corn. Egg yolks were collected and the yolks analyzed for color using reflectance colorimetry. The addition of 3-Nitro-10 at either level

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

open access: yesPoultry
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.

Evaluation of Carotenoid Pigments for Coloring Egg Yolks

open access: yesPoultry Science, 1960
Abstract MUCH has been written about the role of ingested xanthophylls for pigmenting broilers and also for coloring egg yolks. The great majority of this past research, however, involved the feeding of natural ingredients as yellow corn, corn gluten meal, and alfalfa meal, etc., rich in xanthophylls or crude concentrates made from these natural ...
