Abstract

The changes of arborization of secretions of mucous membranes during stimulated sexual cycle in cows have been investigated. It is established that the dynamics of arborization from the oral mucous membranes, the vestibule of the vagina for hormonal stimulation of the sexual cycle has a direct effect on the level of estrogens in cows. Starting from the third day of research, the number of animals in which we observed a clear arborization increased to four (40%), which indicates an increase in estrogen levels. Instead, six animals (60%) lacked arborization. On the fourth day in the estrus stage (insemination day), the number of cows in the smears we noticed a clear arborization increased to 7 (70%). This was the highest rate during the studies and suggests that only 7 cows had the highest estrogen levels at their peak. From the fifth to the 10th day of the study, a gradual decrease in the number of animals in smears was marked by clear arborization. This, in its turn, is associated with the formation on the site of an ovulatory follicle of the yellow body that begins to produce a progesterone, indicating the stage of the meteor shower. At the 12th of observation in smears of one animal was marked a clear crystallization while in the other nine it was absent. Beginning from the 13th to the 21st day, arboretization in the smears from the mucous membrane of prickly vagina was absent. Only on 14, 15, 17, and 20th day it was noticed singular or not clear arborization. At the 22–24th day of observation in one cow, signs of the next sexual cycle were recorded. Namely, in smears, we noticed a clear arborization, which confirms the renewal of sexual cycle and lack of fertilization. Mucus mucous membranes of spit vagina and saliva of cows for spontaneous want have a longer-term character and a clear figure in the form of a leaf of fern than in the induced sexual cycle, where the drawing was less intense and short-lived in the stage of the estrus. According to our data, one can sometimes observe single crystallization in the stage of metetrusus and diestrus. This is what we associate with the selection of smears from the oral cavity after feeding the animals with concentrated foods, acidic silage, and in smears from mucus, vinegar vinegar – functional disorders in the sexual system.
