The chicken hatching egg is a self-contained life-supporting system for the developing
embryo. However, the post-hatch performance of birds depends on several factors, including …

During incubation, the content of the egg is converted into a chick. This process is controlled
by incubation conditions, which must meet the requirements of the chick embryo to obtain …

The paper aimed to study the effects of light regime during the incubation on hatching
performance, body development and serum biochemical indexes in Beijing You Chicken …

Materials and Methods: Four treatments were used to study the impact of various light colors
on the growth of embryos and their neurophysiological traits: Dark without light (D), red light …

The hypothalamic-pituitary-adrenocortical axis can translate, through glucocorticoid
secretion, the prenatal environment to development to produce phenotypes that match …

Providing green light during incubation has been shown to accelerate the embryo
development and shorten the hatching time in broilers. Few studies have concentrated on …

The aim of this study was to evaluate the effect of 16L: 8D photoperiod with green (GREEN)
or white (WHITE) lights during incubation on hatching performance, blood melatonin …

Providing lighting schedule during incubation has been shown to improve chick quality and
reduce stress posthatch. This study was conducted to evaluate the effects of providing light …

Targeted green light photostimulation during the last stage of broiler incubation increases
expression of the somatotropic axis. The purpose of this study was to further shorten the in …

Rhythmic pineal melatonin biosynthesis develops in chick embryos incubated under a light
(L)-dark (D) cycle of polychromatic white light. The spectral sensitivity of the embryonic …
