Topic:Semen Analysis

Semen analysis involves the evaluation of semen quality to assess reproductive potential and health in horses. This process typically includes the examination of several parameters such as sperm concentration, motility, morphology, and volume. Semen analysis is used in breeding programs to determine the fertility of stallions and to identify any reproductive issues. The collected data can assist in making informed decisions about breeding management and interventions. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, findings, and implications of semen analysis in equine reproduction.

[An immunologic study of hyaluronidase of different animal origin].

Veterinarno-meditsinski nauki January 1, 1975 Volume 12, Issue 2 31-38

Kozhukharova L.Studied was the antigenic relatedness of hyaluronidase contained in the semen of breeder animals of homologic and heterologic species. The experiments were carried out by means of the immunodiffusion and the immunoelectrophoretic methods. The results obtained showed that the seminal hyaluronidase of bulls, rams and bucks is antigenically related, and that of stallions, boars and rabbits does not exhibit antigenic relatedness. Stallion semen is closely related antigenically with the above-mentioned three animal species' semen as manifested by two precipitation bands, but these are not identical...

Analysis of the pattern of ejaculation in stallions.

Journal of reproduction and fertility December 1, 1974 Volume 41, Issue 2 329-335 doi: 10.1530/jrf.0.0410329

Tischner M, Kosiniak K, Bielański W.The emission of stallion semen was studied with the aid of an `open' Krak\l=o'\w-72Model artificial vagina. The pattern of mating behaviour was constant in all copulations observed : a mean number of seven intravaginal thrusts was required to elicit ejaculation. The pressure within the vestibule of the artificial vagina averaged 66 mmHg at the beginning of copulation, 142 mmHg just before ejaculation, and 70 mmHg during the emission of semen. Emission appeared to be a more variable process. Five to ten jets were observed; the mean number was eight. The early jets occurred under high pr...
