Abstract
The article reports the new research data on testing the original Russian lubricant gel registered under the Doctor VIC trade name (import substitution) during the semen sampling. The semen was collected with the artificial vagina rubber tube and the disposable polyethylene gloves being labricated with the gel to use the recto-cervical artificial insemination technique and to operate the rectal procedure for clinical examination of cows and heifers with gynecological diseases. The sterile veterinary Likom” Vaseline (Russia) was used as the control remedy for lubricating the artificial vagina. In case of the clinical examination of cows and heifers with gynecological diseases, the 1.0% sodium chloride solution was used. During the tests, 114 semen samples taken from 19 bull sires were analyzed. The behavioral response patterns of 179 cows and heifers with the gynecological diseases were studied during the clinical examination (90 experimental animals and 89 control animals). It has been ascertained that this Doctor VIC lubricant gel can contribute to the favorable environmental conditions during the sperm sample collection in the bull sires, which can be compared with the environments during the natural mating. It was contributed to both increasing the total sperm count in the doublet ejaculates by 13-21% and the number of the frozen semen doses by 12-36% and decreasing the frozen-thawed abnormal sperm by 28-36%, when compare to the control. In case of the rectal examination for gynecological problems, lubricating the disposable polyethylene gloves with the Doctor VIC gel contributed to a significant reduction in aggression and removal of various micro-deformations occurred during the rectal examination (for instance, blood occurrance after the examination), when compared to the control. Therefore, the new original Russian gel registered under the Doctor VIC trade name may be used for current application in the extensive zoo-veterinary practice.
