Abstract Present study was planned to determine variations in external and internal quality egg parameters of different avian species including ostrich Struthio camelus, ducks Anas platyrhynchos, chicken Gallus gallus, turkeys Meleagris gallopavo grey francolin Francolinus pondicerinus. All the birds were kept under similar rearing conditions. A total 150 eggs collected for each record features...

The chicken (Gallus gallus) genome represents an important non-mammalian reference sequence that will greatly facilitate the identification of functional sequences within the human genome. Our recent manuscript describing the draft sequence of the chicken genome touched upon several interesting features with direct relevance to vertebrate genome evolution (Hillier et al, 2004). Even in its curr...

Chicks (Gallus gallus) learned to run from a starting box to a target located at the end of a runway. At test, colourful and bright distractors were placed just outside the starting box. Dark incubated chicks (maintained in darkness from fertilization to hatching) stopped significantly more often, assessing more the left-side distractor than chicks hatched after late (for 42 h during the last t...

A case of oviductal volvulus, a rare disorder with oviductal cyst as a possible aetiology, is described in an 11-month-old Nera black chicken (Gallus gallus domesticus). The condition was observed during routine postmortem examination of 550 carcasses from a flock of 16,100 birds between September 2005 and June 2006. The affected portion of the oviduct and the cyst twisted almost 360 degrees cl...

1. Glycogen was studied in retinas of the chick (Gallus gallus), fixed in Gendre's fluid and stained by the periodic acid/Schiff method. In agreement with some of the earlier data on the subject, obtained with less suitable methods, glycogen was found in the paraboloid of accessory cones and in the characteristically shaped paraboloid of the rods. 2. Basiphilia, observable by means of the gallo...
