Brain alterations in crested versus non-crested breeds of domestic ducks (Anas platyrhynchos f.d.).
A comparison of brain size and brain composition was made between two uncrested duck breeds and Crested Ducks (CR) and between CR individuals that do possess crests and those that do not have the crest. Domestic ducks of the breed CR have allometrically larger brains than uncrested duck breeds. The crest inserts on a cushion of fat and connective tissue that is partly nourished by brain vessels...
متن کاملEndothelin Receptor B2 (EDNRB2) Gene Is Associated with Spot Plumage Pattern in Domestic Ducks (Anas platyrhynchos)
Endothelin receptor B subtype 2 (EDNRB2) is a seven-transmembrane G-protein coupled receptor. In this study, we investigated EDNRB2 gene as a candidate gene for duck spot plumage pattern according to studies of chicken and Japanese quail. The entire coding region was cloned by the reverse transcription polymerase chain reaction (RT-PCR). Sequence analysis showed that duck EDNRB2 cDNA contained ...
متن کاملEmbryotoxicity of Corexit 9500 in mallard ducks (Anas platyrhynchos).
Embryotoxicity of the oil dispersant Corexit 9500 was examined using fertilized mallard duck eggs. Corexit 9500 was topically applied below the air cell to eggs in volumes ranging from 0 to 100 μL on day 3 of incubation. The highest incidence of mortality occurred at developmental stage 4, one day post-Corexit 9500 application. Hatching success was significantly decreased among eggs treated wit...
متن کاملCampylobacter populations in wild and domesticated Mallard ducks (Anas platyrhynchos)
Identifying the Campylobacter genotypes that colonize farmed and wild ducks will help to assess the proportion of human disease that is potentially attributable to the consumption of duck meat and environmental exposure to duck faeces. Comparison of temporally and geographically matched farmed and wild ducks showed that they had different Campylobacter populations in terms of: (i) prevalence, (...
متن کاملSurvey of Migratory Birds (Anatidae: Anas platyrhynchos) for Schistosome Parasites from Mazandaran Province, Northern Iran
BACKGROUND The aim of the present study was to survey birds' schistosomes in migratory birds (Anatidae: Anas platyrhynchos) which are the source of the disease in Mazandaran Province, Northern Iran. METHODS A number of mallards were bought from the markets of hunted birds. The respiratory tracts (nasal mucosa) and intestinal blood vessels were studied for adult worms. The nasal mucosa was sep...
