A meta-analysis on the relationship between goose age and egg weight

Journal of Applied Poultry Research, 2021
SUMMARY: Although many studies have attempted to determine the effect of goose age on egg weight, the relationship remains unclear. We conducted a meta-analysis of the relevant literature in an attempt to provide clarity on this question.

G protein-coupled receptor kinase-2 (GRK-2) regulates serotonin metabolism through the monoamine oxidase AMX-2 in Caenorhabditis elegans. [PDF]

, 2017
G protein-coupled receptors (GPCRs) regulate many animal behaviors. GPCR signaling is mediated by agonist-promoted interactions of GPCRs with heterotrimeric G proteins, GPCR kinases (GRKs), and arrestins.

Effect of inoculation route on the production of antibodies and histological characteristics of the spleen in laying hens

Brazilian Journal of Poultry Science, 2012
Recent studies have reported the use of IgY antibody in the prevention or treatment of diseases in animals. IgY can be obtained in large amounts from the yolk of chicken eggs through a low-cost process. This study evaluated the effect of different routes

Egg-laying [PDF]

WormBook, 2005
C. elegans hermaphrodites are self-fertile, and their rate and temporal pattern of egg-laying are modulated by diverse environmental cues. Egg-laying behavior has served as an important phenotypic assay for the genetic dissection of neuronal signal transduction mechanisms. This chapter reviews our current understanding of the neuronal and neurochemical

Melatonin Improves Laying Performance by Enhancing Intestinal Amino Acids Transport in Hens

Frontiers in Endocrinology, 2018
The high concentration of melatonin (MEL) in the intestinal mucosa suggests that it has a special physiological function in intestine. In hens, previous studies have shown that MEL treatment promoted egg-laying performance.

Estimation of calcitonin and calcitonin gene-related peptide-α in bone calcification in quail during laying period [PDF]

Iraqi Journal of Veterinary Sciences
Maintaining the balance of calcium, phosphorus, and their regulating hormones is essential in laying hens to preserve the quality of the eggs and the framework. However, the physiological regulation of these systems is quite specific.

Ancient origin and maternal inheritance of blue cuckoo eggs [PDF]

, 2016
Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or 'gentes') in avian brood parasites.
