Artificial insemination in mares

Abstract

The aim of our study is to provide valuable insights and recommendations for optimizing the artificial insemination process, ultimately contributing to the improvement of breeding outcomes in mares in Tiaret. We have inseminated artificially 7mares during the mating season (from February to June 2023) at the veterinary institute of Ibn-Khaldun University Tiaret. Semen was collected from stallion using an artificial vagina. Mares were inseminated each 24 - 48h once the follicular diameter reaches 35mm. The results obtained in our study show that the main diameter of pre-ovulatory follicle at the last insemination was 41.43mm. Conception rate is85.71%. The index of insemination is very interesting. Its value is 1.43. The rate of the mares diagnosed pregnant is 66.66%after the first cycle and 16.66%after both the second and the third cycle. In conclusion, according to our results, artificial insemination can improve breeding outcomes in mares in Tiaret. Final year project focuses on the study of artificial insemination in mares. Artificial insemination is a widely used assisted reproductive technique in the equine industry to enhance breeding and genetic selection of horses. In this project, we examine the various procedures employed in artificial insemination in mares, by concentrating on the key factors that influence the success of this technique. We explore aspects such as stallion selection, semen preparation, different insemination methods and ovulation timing. By describing the standard operating procedure for artificial insemination in the mare using fresh and diluted semen, relying on insemination per vagina technique in order to obtain positive results (pregnant mares). Through artificial insemination a mare and stallion are allowed to be mated that under normal circumstances could not be covered naturally. In conclusion, this study provides a comprehensive overview of artificial insemination in mares, emphasizing essential aspects of this assisted reproductive process. The gathered information can be utilized to enhance artificial insemination practices among horse breeders, aiming to optimize conception and fertility rates in mares
