Abstract
The purpose. To investigate anatomical constitution and histological structure of inner sexual organs of goats of Zaanenskaya breed. Methods. Probes of constitution of sexual organs of goats in the age of 7 years was carried out by their dissections after slaughter, measurement of linear dimensions, weighting, sample drawing, preparation of specimens for histological probes, their scanning and documentating. Results. It is fixed that sizes of sexual organs of the examined goats on the average were the following: direct length of left ovary – 2,0 cm, direct length of right ovary – 2,4 cm, average mass of the left ovary – 0,6 g, average mass of the right ovary – 1,1 g. Oviducts had the length: left – 14,2 cm, right – 14,4 cm. Length of horns of uterus, measured on the big curvature, has made: left – 13,7 cm, right – 12,2 cm. Diameter of horns in the middle of their length made for left and right – 2,3 and 2,8 cm accordingly. Body of uterus had the length of 1,8 cm, uteral cervix had the length of 5,9 cm at diameter of 1,8 cm. Its mucosa organized on the average 4,7 cross folds which had a little bit spiral structure. Their tops were directed caudally. The length of vestibule of vagina was in average 4,7 cm. Conclusions. The gained results specify that sexual organs of adult Zaanenskaya goats have constitution and sizes inherent in small-sized cattle. Anatomical features of the port of uteral cervix need to be considered at artificial fertilization of goats which in the future becomes the basic method of reproduction of these animals.
