The structural features of the hen’s oviduct "hajseks white" and italian goose

Abstract

The purpose of our research was to study the features of the anatomical structure of the oviduct in the chicken "Hajhseks white" and Italian goose. As a result of our research, we found that in birds the oviduct is located on the left side and occupies the entire cau-dodorsal part of the thoracic cavity. A chicken and a goose developed only the left oviduct, the right rudimentary. The oviduct is a strongly curved tube that extends from the ovary to the cloaca, filling the caudodorsal part of the left side of the thoracic cavity, touching the left kidney, spleen and intestine. The oviduct is suspended in the thoracic cavity on the dorsal and ventral mesentery, which fix the oviduct in one position. The oviduct is divided into five anatomical and physiological parts of different functions: funnel, Magnum (protein Department), uterus, isthmus and vagina. The average length of the oviduct in a female goose is 322.11±0.85 mm, and in a chicken 319.53±0.85 mm. Morphometric analysis showed that the protein Department of the oviduct is the longest area of the oviduct. Perhaps this is due to the secretory function of albumin. The length of the protein Department is 47.9% in chicken, and in female goose 51.1% to the length of the entire oviduct. Further along the length there is a funnel, it takes 20.5% of the chicken, and the female goose 19.9% to the length of the entire oviduct. The uterus occupies 16.6% of the chicken, and the female goose 15.7% of the length of the entire oviduct. The vagina occupies 17.4% of the chicken, and the female goose 9.4% of the length of the entire oviduct. The shortest part of the oviduct turned isthmus, it takes the chicken 4.1%, and the female goose 1, 87 % of the length of the entire oviduct.
