PECULIARITIES OF STRUCTURE OF COVER AND FLIGHT PIECES OF THE HOUSE CHICKEN(GALLUS GALLUS DOMESTICUS)
Abstract
The features of structure of integumentary feathers of different
pterylae are set are heads, necks, backs, covered, stomach and thigh, and
also comparative description of morphometric parameters of integumentary
feathers of these pterylae is produced. It is set that the chickens of both
breeds on the structure of large fan have integumentary feathers of all areas of
body combined contour. The amount of stroke feathers of the first, second and
third orders is set, and also smoked the amount of steering feathers of tail of
both breeds. The features of structure of flying feathers of the probed breeds
are set smoked. Large contour feathers which dorsal and ventral cover stroke
and steering feathers, on the basis of analysis of their absolute and relative
morphometric parameters, are attributed to the auxiliary flying feathers.
Keywords: home hen, pteriliya, integumentary feathers, flying
feathers, external large fan, internal large fan, bar, calamus, barrel,
