AI Article Synopsis

  • Coronaviruses are primarily found in birds, particularly in migratory ducks that can spread pathogens, leading to significant economic consequences.
  • A study conducted in Portugal collected stool samples from 72 migratory ducks, with 24 samples testing positive for coronaviruses, which were closely related to strains found in ducks from other countries.
  • This research is notable as it is the first to document the presence of coronaviruses in wild ducks in Portugal, highlighting the importance of birds in dispersing microorganisms in various ecosystems.

Article Abstract

Coronaviruses (CoVs) are part of the family, and the genera Gamma (γ) and Delta (δ) are found mostly in birds. Migratory birds have an enormous potential for dispersing pathogenic microorganisms. Ducks (order Anseriformes) can host CoVs from birds, with pathogenic expression and high economic impact. This study aimed to identify and characterize the diversity of CoVs in migratory ducks from Portugal. Duck stool samples were collected using cloacal swabs from 72 individuals (, and ). Among the 72 samples tested, 24 showed amplicons of the expected size. Twenty-three were characterized as and one as (accession numbers ON368935-ON368954; ON721380-ON721383). The sequences showed greater similarities to those obtained in ducks () from Finland and Poland, duck from the USA, and mute swans from Poland. Birds can occupy many habitats and therefore play diverse ecological roles in various ecosystems, especially given their ability to migrate exceptional distances, facilitating the dispersal of microorganisms with animal and/or human impact. There are a considerable number of studies that have detected CoVs in ducks, but none in Portugal. The present study assessed the circulation of CoVs in wild ducks from Portugal, being the first description of CoVs for these animals in Portugal.

The aim of this study was to compare two different strains of Pekin duck and to answer one scientific hypothesis: 1) Strain and sex influence live body weight, hot and cold carcass weights and carcass portions weights and yields, fatty acid content, fatty acid total cholesterol and α-tocopherol contents of meat. The study used 50 individuals of each strain in comparison (Cherry Valley and Grimaud) equally divided between both sexes), raised in equal rearing and feeding conditions. The results show that, when raised in equal rearing and feeding conditions and slaughtered at matching age, the strain had no significant influence on live body weight at slaughter, warm and cold carcass weights.

Article Synopsis
  • The study, conducted from July 2022 to March 2023, examined 148 domestic birds from traditional markets in Guilan province for gastrointestinal helminths, finding a 42.56% prevalence of parasitic infections.
  • Morphological and molecular analyses identified specific helminth species, with varying infection rates, and showed high genetic similarities of the isolates to known sequences in GenBank.
  • The study emphasizes the need for effective parasite management strategies, including monitoring and sanitation, while suggesting further research to evaluate the impact of these parasites on poultry health and productivity.

The mallard duck or wild duck (Anas platyrhynchos) is the world's most widespread and numerous dabbling duck, being traditionally hunted across many countries in Europe and North America. This study aims to provide a detailed characterization of mallard duck's meat lipid fraction obtained from farmed specimens, reared for hunting purposes, under semiextensive conditions. The mallard's duck meat total lipid content averaged 2.
