Liver Histogenesis in Chukar Partridge (Alectoris Chukar) Embryo

Liver Histogenesis in Chukar Partridge (Alectoris Chukar) Embryo

Introduction: In chick embryo, endodermal component of the liver becomes split into 2 diverticula in a short time. The anterior diverticulum lies to the left of the ductus venosus and the posterior one to its right side. As the liver primordium grows, it is invaded by the embryonic veins. Based on the different incubation time periods and evolutionary origin of avian species...

Parasitosis of the chukar partridge, Alectoris chukar in North Iraq.

OBJECTIVE The aim of this study was to establish the identity of the parasitic communities of the chukar partridge from Iraq as well as reporting on the prevalence and intensity of various infections from several localities and comprising both sexes. METHODS Twenty-nine live adult chukar partridge (Alectoris chukar) were obtained from several localities across the northern provinces of Iraq. ...

Effect of halofuginone (Stenorol) on Chukar partridge (Alectoris chukar).

This study was conducted to assess the effect of the coccidiostat halofuginone (Stenorol) on growth, feed consumption, and survival of Chukar partridge. Halofuginone was fed to three replicates (14 chicks per replicate) of chukar chicks from 2 to 7 d of age at levels of 0, 1.5, 3.0, 6.0 and 12 ppm. Mortality from 2 to 7 d was 0, 0, 0, 11, and 21 birds, respectively, by treatment. Seven-day body...

Global warming, Bergmann's rule and body mass ± are they related? The chukar partridge (Alectoris chukar) case

Using museum specimens collected in Israel during the second half of the 20th century, no support was found for the hypothesis that body mass and tarsus length of chukar partridges Alectoris chukar has changed as a result of global warming. Body mass showed ̄uctuations during the year, reaching a maximum in late winter and spring and a minimum in summer. Bergmann's rule predicts that in warmblo...

Histomorphogenesis of the Chukar Partridge (Alectoris Chukar) Knee Joint

Introduction: There are differences in the pattern of the knee joint formation of the studied species. According to the small number of studies which focused chronologically on the avian knee histomorphogenetic events, its “morphogenetic pattern” is hard to be proposed. The present work was designed to identify the sequential events of the knee formation in the partridge embryo. Regarding to di...
