Abstract


In this work the study of the structure and features of development in the ontogeny of the bone marrow of Guinea fowls of the Volga white breed. Bone marrow is located in the cells of the spongy substance, and with age, its absolute mass increases, and the relative mass is reduced. In the period from 1 to 60 days age was observed the highest content of bone marrow in the skeleton of a Guinea fowl. In males the number of bone marrow more than females, in average by 1.5-2%. The bulk of the marrow from the Guinea fowls at the age from 1 to 90 days are in the peripheral skeleton, more than 55% in the pelvic limbs. The axial skeleton of the Guinea fowl at this age contains about one third of all bone marrow and much of it is concentrated in the spinal column. With age, the saturation of the axial skeleton bone marrow sharply increases and reaches to 48.1% of the total content in the skeleton of a Guinea fowl. The peak saturation of the skeleton by bone marrow observed in the first two months of life Guinea fowls. Then this figure was relatively stable until the age of 90 days varies slightly. With 180 day age, there is a sharp drop of saturation of the skeleton of a Guinea fowl bone marrow. At one year of age, the figure is only 57-59% of the saturation of the skeleton by bone marrow at the age of 90 days. With age, red marrow is replaced by yellow bone marrow. Microscopy of smears of bone marrow of individual fat cells found in red bone marrow in the daily age. At the age of 60 days there is a replacement of red bone marrow yellow 20-28%, and in 90 days in 40%. At the age of 365 days, almost the entire bone marrow is represented by yellow.
