We conclude that laying Pekin ducks prefer manipulatable nest substrates and accessing one is important enough to pay a cost. The results indicate that a manipulatable substrate should be provided to commercially farmed nesting ducks.Lorelle Barrett...
Pekin ducks are the domesticated form of the mallard duck (Anas platyrhynchos)25, the most abundant wild duck species in the Northern hemisphere, and a well-known natural host of gs/GD HPAIV. Mallards exhibit complex migratory patterns, and frequently switch between partly resident and partly ...
William Mason (Philadelphia) found the duck hepatitis B virus (DHBV) in Peking ducks outside China as well and characterized it as HBV-like. DHBV was also hepatotropic,

Twelve laying Pekin ducks previously trained in an operant push-door task were required to use a push-door to access their nest. The door was loaded with increasing weight (0-160% of individual BW, four nights per workload) and eventually blocked to prevent nest access. Before testing, ...
Analysis of thevp1gene revealed that 30.8% of the sequences obtained belonged to a variant of the virus known as novel GPV, so far attributed to short beak and dwarfism syndrome in Pekin ducks. The majority of the GoCV genomic sequences exhibited high homology to the Polish sequence, which...
BMP7 promotes morphogenesis and cell differentiation, including the development of adipose tissue [34]. The SPP1 protein is involved in osteoclast function and contributes to skeletal muscle development in cattle and ducks [35,36]. ITGB1 influences osteoblast function, including cell compaction and mi...
