Malignant Melanoma in a Female Mallard Duck (Anas platyrhynchos)
Melanomas are malignant neoplasms originating from melanocytes. They reported in birds. In this case, macroscopic and microscopic (the histopathologic and IHC) findings supported a final diagnosis of cutaneous malignant melanoma in a mallard duck (Anas platyrhynchos). A female mallard duck (Anas platyrhynchos) was observed with a mass on the ventral portion of the neck. Th...
متن کاملConditioning to magnetic direction in the Pekin duck (Anas platyrhynchos domestica).
The ability of ducks to derive magnetic direction information was tested in a conditioned procedure and the functional properties of the mechanism of magnetoreception investigated using common manipulations. Twelve ducks were trained to find a hidden imprinting stimulus behind one of three screens in a round arena. Once a criterion was reached, the directional choices of ducks were recorded in ...
متن کاملA genetic and cytogenetic map for the duck (Anas platyrhynchos).
A genetic linkage map for the duck (Anas platyrhynchos) was developed within a cross between two extreme Peking duck lines by linkage analysis of 155 polymorphic microsatellite markers, including 84 novel markers reported in this study. A total of 115 microsatellite markers were placed into 19 linkage groups. The sex-averaged map spans 1353.3 cM, with an average interval distance of 15.04 cM. T...
متن کاملCaecal Development in Kuttanad Duck (Anas Platyrhynchos Domesticus)
Caecum, the largest part of duck’s intestine has an important role in liquid absorption, cellulose digestion and defensive mechanism. Age related changes in the histomorphology of the caeca in Kuttanad ducks were studied in 72 birds from day-old to adult at fortnight intervals. After recording the biometry and gross features, the material was fixed in neutral buffered formalin and standard proc...
متن کاملConditioned response to a magnetic anomaly in the Pekin duck (Anas platyrhynchos domestica) involves the trigeminal nerve.
There have been recent calls to develop protocols that collect unambiguous measures of behaviour using automatic techniques in conditioning experiments on magnetic orientation. Here, we describe an automated technique for recording the behaviour of Pekin ducks in a conditioning test that allows them to express unrestricted searching behaviour. Pekin ducks were trained to find hidden food in one...
