Isolation and whole genome sequencing of North American lineage class I avian orthoavulavirus 1 isolated from wild Eurasian teal in South Korea
We report the first North American origin class I avian orthoavulavirus 1 (AOAV-1) isolated from a faecal dropping of wild Eurasian teal (Anas crecca) in South Korea. Whole genome sequencing and comparative phylogenetic analysis revealed that the AOAV-1/Eurasian teal/South Korea/KU1405-3/2017 virus belongs to the sub-genotype 1.2 of class I AOAV-1. Phylogenetic analysis suggested multiple introductions of the North American sub-genotype 1.2 viruses into Asia and its establishment in the wild bird population in East Asia since May 2011. These results provide information on the epidemiology of AOAV-1, particularly the role o...

Bioefficacy of Dietary Inclusion of < em > Nannochloropsis oculata < /em > on < em > Eimeria spp. < /em > Challenged Chicks: Clinical Approaches, Meat Quality, and Molecular Docking
Avian Pathol. 2024 Jan 29:1-30. doi: 10.1080/03079457.2024.2312133. Online ahead of print.ABSTRACTAbstractAnticoccidial drugs have been used to treat avian coccidiosis for almost a century, but drug resistance, bird harm, and food residues have produced human health issues. Therefore, Nannochloropsis oculata was studied as a potential chemotherapeutic alternative for broilers affected with coccidiosis. A total of 150 one-day-old male Cobb broiler chicks were treated as follows: G1-Ng: fed a basal diet; G2-Ps: challenged with Eimeria spp. oocysts and fed basal diet; G3-Clo: challenged and fed basal diet with clopidol; G4-NO...

Epidemiological investigation of fowl adenovirus (FAdV) infections in ducks and geese in Shandong Province, China

A walk through the broiler breeder life: how do footpad dermatitis and gait scores develop from rearing to slaughter?
This study is the first to investigate FPD and gait scoring in broiler breeders during their lifespan from rearing to end of life. In total, eight flocks were monitored (four Ross and four Hubbard) at five different timepoints, in rearing (5 and 15 weeks of age), during the production period (25 and 45 weeks of age) and at the end of the production period (approximately 60 weeks of age). At each visit, 50 hens and 25 roosters were gait scored (six-point scale) and footpads from another 50 hens and 25 roosters were evaluated (five-point scale) (total n = 3000 breeders, 2000 hens and 1000 roosters). Litter quality and air qu...
