The method of preparation and use of vasectomized stallions to regulate the sexual function in mares during hippodrome testing

Abstract

The objective of this study was to develop a method of preparation and use of vasectomized stallions, and to test them as a factor preventing genital functional disorders in mares during training and hippodrome testing. Thoroughbred mares of English, Arabic and Akhal-Teke breeds owned by horse ranches of the Republic of Kazakhstan were used in the research. Vasectomy techniques were mastered on a slaughtering material, and then field tested on stallions. A series of experiments were set for comparative evaluation of various methods of preparation and use of a vasectomized stallion, resulting in a technique based on removing the front section of sperm ducts in the ventro-caudal portion of the scrotum. The developed method is convenient, safe, and easy to perform in field conditions. The surgery is not time consuming, and there are no postoperative complications. We found a positive effect of the vasectomized stallion on the course of the mares' oestrous cycles, on their performance during hippodrome testing, and their reproductive function. The method reduced the standing heat period, and the mares quickly recovered their performance. Thus, it decreased the time of the mares' elimination from the training schedule and had a positive effect on the performance during hippodrome testing. The use of a vasectomized stallion during training significantly predetermined the course of the mares' reproductive cycle after completion of the hippodrome testing. The results of this study are relevant to the practical needs of sport horse breeding. Horse, scrotum, heat period, prevention, sperm ductsReproduction and improving the quality of horses is one of the main objectives of the horse breeding farms. Nonpregnant mares have several sexual cycles within a specific

Epizootiological aspects of natural nidality of Ixodes tick-borne borreliosis in the Moscow region (Russian Federation)

“…It can take from 1 to 2 h between a tick bite and actual infestation of a person with Borrelia. Painful sensations occur only 6-8 h after the tick bite, while it usually takes several days for the female tick to saturate with blood [32][33][34].…”

Comparative study between the excision-ligation and autoligation of vas deferens technique for teaser rams preparation

“…This was due to in week 3 the ejaculation had sperm in both techniques while the spermatozoa disappeared at week 4 post-operation. In fact, numerous authors such as Julanova et al , [11] Barone et al , [15] Sokal et al , [16] Cook et al , [18] Ibrahiem [20] demonstrated different techniques to create vasectomized patients. In the present study, the reproductive efficient examination of both techniques did not establish the significant differences between the EL and AL techniques.…”

“…These methods depend on males have the ability to mate the female without ejaculation. Vasectomized males are modified surgically so retain natural sexual desire may occur, but this method is occlusion of the sperms’ passage [11]. The first and oldest method was excision-ligation (EL) of vas deferens [12].…”
