Description of the Anser anser goose karyotype.
The karyotype of the Italian goose originating from Anser anser was characterised on the basis of R and C bands. Chromosomal preparations obtained from an in vitro culture of blood lymphocytes were stained with the RBG and CBG techniques. The RBG technique enabled the analysis of the structure of nine pairs of chromosomes whereas the CBG technique - fourteen pairs ofchromosomes from the total o...
متن کاملJuvenile Greylag Geese (Anser anser) Discriminate between Individual Siblings
Social species that maintain individualised relationships with certain others despite continuous changes in age, reproductive status and dominance rank between group members ought to be capable of individual recognition. Tests of "true" individual recognition, where an individual recognises unique features of another, are rare, however. Often kinship and/or familiarity suffice to explain dyadic...
متن کاملIsolation of various Arcobacter species from domestic geese (Anser anser).
In this study, the prevalence and distribution of various Arcobacter spp. were investigated in samples taken from the cloacae of healthy domestic geese raised in Turkey. A membrane filtration technique with a non-selective blood agar was employed after enrichment in Arcobacter enrichment broth (AEB) to isolate a wide range of Arcobacter spp. In addition, the isolates were characterized phenotyp...
متن کاملMaedi - visna PALL
Rise in temperature is not observed in visna or maedi. The animals seem to be remarkably alert and the appetite remains unaffected throughout. The period between inoculation of infective visna material and the development of clinical signs varies from animal to animal even with a standard dose. Usually this period is very long and several months to several years may elapse before clinical signs...
متن کاملStress assessment in captive greylag geese (Anser anser).
Chronic stress--or, more appropriately, "allostatic overload"--may be physiologically harmful and can cause death in the most severe cases. Animals in captivity are thought to be particularly vulnerable to allostatic overload due to artificial housing and group makeup. Here we attempted to determine if captive greylag geese (Anser anser), housed lifelong in captivity, showed elevated levels of ...
