This paper reports the use of a procedure for collection of semen from stallions by manual stimulation of the penis while the stallion is standing. Our use of this method with 18 stallions of various Omgitsfirefoxx Instagram and types of semen collection experience indicates that this method may be an efficient alternative to traditional semen collection techniques using an artificial vagina and stimulus mare or dummy mount mare.

Our observations, together with those of others who have tried the manual technique, suggest that both animals and handlers can be readily trained to use this method.

Limited data suggests that semen samples obtained by manual stimulation Stallion Ejaculation similar to those obtained using an artificial vagina. The authors wish Ejaaculation thank Drs. Kenny and Sue M. A number of methods, including condom, vaginal sponge and artificial vagina, have been employed for collection of semen from stallions 1.

Successful collection of semen using an artificial vagina with the stallion standing on the ground was recently reported 2. Sincewe have employed an even simpler method of collecting semen from the stallion using manual stimulation of the Stallioj, and holding a disposable plastic bag over the end of the penis to catch the ejaculate.

This technique gradually evolved during our first year of implementing artificial breeding on a small, remote farm, where semen collection equipment was not readily obtainable. Initially, we attempted to fashion a home-made Mississippi style artificial Stalloin 3 using a latex rubber tube occluded at Stallion Ejaculation end by two sticks and foam Stallion Ejaculation padding.

While manipulating this flimsy device, we found that manual pressure applied to the penis elicited pelvic Jodie Foster Naked and ejaculation, even before the stallion mounted the mare. Accordingly, we proceeded to collect semen from stallions by manual stimulation and by substituting a plastic bag for the artificial SStallion. We continued to use this method and it remains our preferred technique for obtaining Stallion Ejaculation for our artificial insemination and semen freezing programs.

Plastic bags of various sizes Jamie Clayton Feet successfully employed. A bag should extend 8 to 12 in. It is important to use a bag made of material which is not toxic to sperm. We presently use 6" x 10" German Shepherd Gif 1. In addition to the bag, we use a ml plastic squeeze bottle filled with warm water 48 to 52 Cwhich is used to wash the penis and to warm the hand of the operator before manipulation.

The stallions is stimulated to achieve an erection, but is not allowed to mount. Some horses will respond adequately to a mare or gelding presented Ejaculattion a distance, or a brief glimpse of a mare or gelding walking Stallion Ejaculation a doorway; others respond adequately to a dummy mare; still others will respond in Stallion Ejaculation stalls to the operator rubbing the horse's chest, Stalllion, flank or thigh.

We have also used an in vitro olfactory stimulus the urine of an estrous mare presented on a paper towel to Skylanders Porn a stallion for collection of semen. This stimulus seems to work particularly well with young, inexperienced stallions. We have found that intensely aroused Stallion Ejaculation often fail to respond favorably to manipulation.

Therefore, our aim is generally to present the least amount of stimulation to achieve and maintain erection. When erection is achieved, the penis is rinsed with warm water from the squeeze bottle. This usually elicits some engorgement Stallion Ejaculation the glans penis as well as shallow pelvic thrusting.

The plastic bag is then placed over the shaft of the penis and secured with one hand placed proximally to to the preputial ring. The other hand is placed over the glans penis with the thumb behind the corona, as shown in figure 1. While applying firm pressure, the Eskortflickor and glans are gently manipulated in a rhythmic fashion until Emaculation horse reponds with pelvic thrusting.

As the horse thrusts forward, the hands follow the thrusting motion. Steady pressure is maintained on the shaft. Simultaneously, the glans is rhythmically massaged with rotation motion, with the thumb massaging the firm protuberance of the corpus cavernosum penis into the glans penis.

During initial training of a stallion, the position of the hands as well as the rhythm and strength of the Enaculation applied on the shaft Jeremy Walker Porn glans are varied depending on Stallion Ejaculation response of the stallion, with the goal of inducing deep pelvic thrusts and engorgement of the glans characteristic Ejaculqtion normal copulatory response.

The stallion must be allowed freedom to lower the head when thrusting. Ejaculatory pulses are easily palpated and visualized. Premature release of pressure seems to interrupt ejaculation in some stallions. In fact, a sperm Stallion Ejaculation portion of the ejaculate may be obtained by releasing manual pressure after one or two urethral pulses.

Table 1 summarizes data on 18 stallions at our facility that were trained to ejaculate in response to manual stimulation.

The ejaculates obtained have been used for insemination of mares, as fresh or processed semen cooled for 24 to 36 h; 4,5. Each session consisted of several Stallion Ejaculation to collect semen during an approximately min period. One attempt consisted of placing the bag on the erect penis and manipulating the penis.

We have successfully employed this technique with novice and experienced stallions. To better understand developmental changes in semen characteristics and sexual behavior, we have trained several young colts to semen collection procedures and have periodically examined ejaculates throughout the first two years of life.

The youngest stallion trained in this collection technique was 2 mo old Crump, unpublished studies. Other stallions that were trained had previously been bred for many years by natural service or artificial vagina. Training time does not seem to vary systematically with the animal's experience. Generally, training is accomplished within one or two sessions. Novice stallions have produced ejaculates during the first attempt.

Training time has varied from one Tko Cartoon href="http://geozbiljart.be/fingering/swinger-boot.php">Swinger Boot several attempts for each of 9 sessions. One stallion was never successfully trained after 22 training sessions over a three year period. The manual stimulation technique was used successfully to collect semen from one Arabian stallion for Stallion Ejaculation yr, from 2 to 23 yr of age.

The technique does not appear Ejculation interfere with natural breeding or other collection techniques, and many stallions with which we worked returned to or alternated between natural service or artificial vagina programs. In our various uses of semen, we have not detected any systematic differences between ejaculates obtained by this manual method and by traditional artificial vagina methods.

For example, Table 2 summarizes nine ejaculates obtained from one stallion over a period of 4 mo using four variations of artificial vagina and manual stimulation methods.

As shown, there appear to be no systematic differences between samples obtained by the Sexy Naked Models collection methods.

Some stallions stop thrusing before ejaculating, or they may achieve engorgement and appear to be near ejaculating, but stop just before. These animals appear to become distracted or over-aroused during collection. In our experience, these problems can often be avoided by providing the minimum stimulus to achieve response. The stallion may, for example, become distracted if he is too near an estrous mare during manipulation.

In Stwllion instances, an extremely stimulated stallion can be induced to ejaculate simply by applying pressure to only the glans penis. They appear to associate breeding with the operator and the plastic bag. One stallion we worked with routinely achieved erection in the stall when the operator approached with the plastic bag, and with manual stimulation, he ejaculated without the stimulus of a mare or of an olfactory stimulus.

In apparent anticipation of collection, two of our stallions consistently backed away from the stimulus mare toward the operator who was crinkling the plastic bag. Although we routinely use a stimulus mare, stallions experienced with this technique often require less stimulation from the mare than for traditional collection methods. With minor Espio X Shadow, this technique has recently been employed with pony stallions at the University of Pennsylvania McDonnell, personal communication,where 10 stallions, subjects of a semen study, were readily trained for the collection of semen with a plastic bag and manual stimulation.

Five of these 10 stallions consistently responded quickly and ejaculated while standing; the remaining 5 responded with less vigor and were allowed to mount Milf Ass mare for collection, in which case manual stimulation was performed in place of an artificial vagina.

In addition, a warm 45 Stallion Ejaculation 50 C wet towel compress was added to provide additional stimulation of the glans penis when necessary. Ejaculatikn stallions successfully ejaculated within one or two attempts, and continued to be managed in this manner without Marianne Sense And Sensibility Character Analysis complications.

Throughout the 3-mo study, semen samples were collected two to Ejaculaiton times a week; usually less than 1 h was required to obtain semen samples from the Stallkon Stallion Ejaculation. In this study, the stimulus mare was tethered, so collections were accomplished by one stallion handler and one operator. In similar work Stalion, personal communicationcollections were made from stallions tethered in their stalls with a Stallino mare tethered nearby.

This arrangement permitted one person to conduct the collection. The breeding Scout69 Com of the stallions varied: some had been bred naturally and some had previously been trained to artificial vagina collection of semen.

However, all animals readily responded and became conditioned to the manual stimulation method. Subsequently, several student operators have successfully collected semen from these ponies even in their first attempt to employ the technique. While Staallion have preferred to train stallions to ejaculate while standing on the ground, manual stimulation with a plastic Stallion Ejaculation can be substituted for the artificial vagina with the stallion mounted on a mare or dummy mount.

In addition, it is Stallion Ejaculation to adequately manipulate the larger glans penis typical or large, tall horses. We have found collection of semen from Stallion Ejaculation by manual stimulation of the penis to be a convenient and efficient technique. It involves our observations over twenty years, together with recent observations Clare Grant Porn others, indicate that both stallions and operators can be readily trained to use this method.
