Analysis of selective sweeps to pinpoint causative genomic regions involved in chicken domestication has revealed a strong selective sweep on chromosome 4 in layer chickens. The autoregulatory α-adrenergic receptor 2C (ADRA2C) gene is the closest to the selective sweep and was proposed as an important gene in the domestication of layer chickens. The ADRA2C promoter region was also hypermethylat...

introduction: neonatal jaundice has a significant prevalence, and in severe cases, causes permanent neurological sequela. many studies have carried out on neonatal jaundice and its predisposing and exacerbating factors. on the other hand, delivery method (cesarean vs vaginal) has been suggested as a predisposing factor for many of neonatal complications in many studies. the aim of this study is...

Background: Feeding behavior is regulated by a complex network which interacts via diverse signals from central and peripheral tissues. It is known dopaminergic and glutamatergic systems have crucial role on food intake regulation but scarce reports exist on their interaction in appetite regulation in broilers. OBJECTIVES: The present study was designed to examine the role of glutamatergic syst...

Evidence has been reported that the proximal small intestine of the neonatal rat selectively transports antibodies into the circulation. This study describes the morphology of the absorptive epithelial cells in this region of the intestine and their transport of several immunoglobulin tracers: ferritin-conjugated immunoglobulins (IgG-Ft) and antiperoxidase antibodies. Cells exposed to rat IgG-F...

Dendrite morphology of neurons provides a structural basis for their physiological characteristics, and is precisely regulated in a cell type-dependent manner. Using a unique transposon-mediated gene transfer system that enables conditional and cell-type specific expression of exogenous genes, we investigated the role of cadherin on dendritic morphogenesis of horizontal cells in the developing ...

Reovirus was isolated from commercial rabbit colonies in farms at KafrElsheikh and El-Gharbia Governorate with a history of neonatal hydrocephalus and blindness. The affected neonates exhibited hydrocephalus at age from 3-20 days with seasonal incidence at a late summer and early autumn (August, Sept. and Oct.). The gross lesions observed at necropsy were bulging of the skull, collapse of the c...

We quantified chicken calpain 2 (CAPN2) expression in two Chinese chicken breeds (mountainous black-bone chicken breed [MB] and a commercial meat type chicken breed [S01]) to discern the tissue and ontogenic expression pattern and its effect on muscle metabolism. Real-time quantitative PCR assay was developed for accurate measurement of the CAPN2 mRNA expression in various tissues from chickens...

The purpose of this study was to investigate the effects different levels palm kernel meal (PKM) on diets layer KUB (Kampung Unggul Balibangtan) chicken. Local feed included in various PKM at 0% (T1), 10% (T2) and 20% (T3). This research conducted 2019 beginning period. One hundred forty-four 22-week-old birds were selected from a flock randomly allocated three treatments with 3 replicates diet...

MicroRNAs (miRNAs, miRs) encompass a class of small non-coding RNAs that often negatively regulate gene expression. miRNAs play an essential role in skeletal muscle, determining the proper development and maintenance of this tissue. In comparison to other organs and tissues, the full set of muscle miRNAs and its expression patterns are still poorly understood. In this report, a chicken skeletal...
