Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

The Microbiota Contributes to the Control of Highly Pathogenic H5N9 Influenza Virus Replication in Ducks

Journal of Virology, 2020
Ducks are frequently infected with avian influenza viruses belonging to multiple subtypes. They represent an important reservoir species of avian influenza viruses, which can occasionally be transmitted to other bird species or mammals, including humans.

Genetic parameters of mule ducks meat and fatty liver performances simultaneously estimated in both parental liness : [Preprint] [PDF]

, 2009
Genetic parameters of traits related to hepatic lipid metabolism, carcass composition and products quality of overfed mule ducks were estimated on both parental lines of this hybrid: the "common duck" line (C), for the maternal side and the "Muscovy ...

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Camera traps offer reliable estimates compared to ground surveys for monitoring duck pairs and broods

Wildlife Society Bulletin
Monitoring breeding waterfowl populations with ground‐based pair and brood surveys informs management and conservation decisions. However, surveys are often limited temporally and may miss individuals that are not present or available for detection at ...

Species Abundance Modelling of Arctic-Boreal Zone Ducks Informed by Satellite Remote Sensing

Remote Sensing
The Arctic-Boreal zone (ABZ) covers over 26 million km2 and is home to numerous duck species; however, understanding the spatiotemporal distribution of their populations across this vast landscape is challenging, in part due to extent and data scarcity ...

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

Animal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

Phylogenetic Relationships of Mitochondrial DNA Cytochrome b Gene in East Asian Ducks

The Journal of Poultry Science, 2007
The ducks (Anas platyrhynchos domestica) were domesticated from Mallard (Anas platyrhynchos). While the ducks bred in Japan and European countries are supposed to originate from the ducks in China and Southeast Asian countries, respectively, the ...

Modeling highly pathogenic avian influenza transmission in wild birds and poultry in West Bengal, India. [PDF]

, 2013
Wild birds are suspected to have played a role in highly pathogenic avian influenza (HPAI) H5N1 outbreaks in West Bengal. Cluster analysis showed that H5N1 was introduced in West Bengal at least 3 times between 2008 and 2010.

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.
