So what is a rig horse we are going to find out it in this article. Horses that have both testicles removed but still exhibit overt male behavior are sometimes called fake mounts. One of the reasons for the persistence of male behavior after castration is the production of extra gonadal androgen. And one of the proposed sources of extra gonadal androgens is the epididymis. The inability to remove all epididymal tissue during castration is sometimes associated with the persistence of male behavior. So horses that exhibit this behavior are generally considered circumcised. So it is unlikely to be accidentally abandoned during castration. The epididymis does not produce or release androgens therefore. Failure to remove all epididymal tissue should not be considered a cause of male behavior. 2 Therefore, there is no proud horse.
What is a rig horse – Behavior
Maintenance of male behavior is also associated with testosterone production by the adrenal cortex. Stimulated by increased plasma luteinizing hormone concentrations in response to decreased plasma testosterone concentrations after castration. There were no more false axons than geldings that did not exhibit male behavior; therefore, maintenance of male behavior after castration should not be attributed to testosterone production by the adrenal cortex.
Males’ mishandling behavior should be attributed to innate behaviors that occur during normal social interactions between horses, rather than extra gonadal production of androgens. Of other horses, about 5% are aggressive towards humans. 3 In horses castrated before puberty. The advantage of male behavior is comparable to that of horses castrated after puberty. Therefore, at the time of castration, owners should be aware that surgery may not completely eliminate or prevent the development of male behavior. So if the horse continues to exhibit any form of poor male behavior. They may misinterpret the competence of the surgeon. Castration can be avoided if performed correctly. .
Diagnosis of the horse
The first step in determining the reasons for persistent behavior in men after castration is to determine whether the behavior is caused by hormones. Examination of each vaginal ring and surrounding area by rectal palpation may help determine whether failure to remove the abdominal testicles is responsible for the continued production of testosterone and maintenance of male behavior. Rectal palpation of the abdominal testes is irrefutable evidence of incomplete castration of the horse.
However, palpation of the abdominal testis is difficult because the testis is small and flaccid, and the abdominal testis often has a wide range of motion allowed by the elongated testicular ligaments themselves. An experienced clinician can usually palpate the rectus abdominis testis. But failure to palpate the testis should not be considered conclusive evidence of the absence of the testis. Likewise, rectal palpation of the vaginal ring should not be considered evidence that the testis has descended through the vaginal ring, as the vaginal ring can also be palpated only if the epididymis descends through the vaginal ring.

Trans rectal or trans abdominal ultrasonography of the abdomen may help detect cryptorchidism. The area of the vaginal ring when the probe is moved forward on the skull. 5 For trans abdominal imaging of the abdominal testis, the probe should be applied longitudinally to the groyne and advanced toward the skull in a back-and-forth motion between the midline and the flanks. On ultrasound, the testicular parenchyma appears as a homogeneous spherical structure surrounded by a more echogenic testicular sac.
