Динамика роста и развития яичников крольчих с момента рождения до полового созревания

The morphological study of the reproductive system, in particular the peculiarities of the structural and age dynamics of ovarian development in rabbits in postnatal ontogenesis, is of great theoretical and practical importance for solving the problems of livestock reproduction. Knowledge of biological features during various periods of ontogenesis allows you to determine the natural state of the ovaries, and diagnosing pathologies of various nature only in a timely manner. Rabbits were the object of research, and ovaries were the object. When performing histological studies of rabbit ovaries in the age aspect, the following indicators were determined: the diameter of Pfluger balls, the area of primordial follicles and the diameter of oocyte nuclei, the area of primary, secondary and tertiary follicles, the area of their oocytes with a diameter of nuclei, the thickness of the teka and shiny shell of secondary and tertiary follicles, the diameter of hemocapillars. Research was carried out in the conditions of the rabbitbreeding farm of the Vitebsk region of the Republic of Belarus, the prosector and laboratory of the Department of Pathological Anatomy and Histology of the Vitebsk Order of the Badge of Honor of the State Academy of Veterinary Medicine. A histological examination of the ovaries found that at birth rabbits have an unconformed ovary in terms of structural structure, they acquire their classical definitive structure only by monthly age. The regularity of growth is noted up to four months of age, where fully formed structural elements of the gland are already observed, but it is not advisable to let rabbit in the case at this age, due to the lack of a sufficiently strong body for carrying offspring. Thus, the research results deepen, expand and supplement the data on the age morphology of fur animals and can be a criterion for their assessment in practical veterinary medicine and in rabbit breeding as a whole.
