In the human and equine species, different kinds of free floating intra-articular particles are related to certain disorders. Osteochondral fragments formed during osteochondrosis dissecans are the most common finding in the equine species, whereas in humans rice bodies due to rheumatoid arthritis are more frequent. Herein we report a third type of floating body inside the stifle of an adult dr...

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 ages 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 d...

Two mature breeding stallions were evaluated because of specific ejaculatory dysfunction, and each was found to have aortic-iliac thrombosis occluding 60 to 70% of the aortic lumen. In each case, the stallion had strong libido, normal mounting, and vigorous initial thrusting. With continued exertion, thrusting became weak and dismount was awkward. Treatment aimed at maximizing sexual arousal be...

Administering altrenogesta to mature stallions at the labeled dosage (0.044 mg/kg) for 30 days had no effect on spermatozoal quantity or quality, with only minimal effects on stallion behavior at 30 days following treatment. However, this regimen of altrenogest significantly suppressed blood plasma concentrations of luteinizing hormone, testosterone, estrogen conjugates, and inhibin at the end ...

This case describes the clinical and radiographic appearance, medical treatment and long-term followup of a 6-year-old French trotter stallion that was referred with an acute onset of pain and swelling at the tail-head without a history of traumatic insult. Radiographic examination revealed multiple semicircular and millet-sized radiolucencies at the endplates of several adjacent caudal vertebr...

The technique (sperm chromatin structure assay) used in this study identifies one reason (a decrease in chromatin quality) for stallions whose semen shows reduced fertility when chilled. This assay is a diagnostic test, in addition to the use of sperm motility and morphologic evaluation, to evaluate the quality of chilled stallion semen and further aid the practitioner and the breeding industry...

rupture of the peroneous tertius was diagnosed in a 7-year-old stallion, based on clinical examinations.the stifle joint flexed as the limb was advanced forward without flexing the hock. when the limb was pulledbackward, the hock joint extended but the stifle was in the normal position. the recommended treatmentincluded complete stall rest for 6 weeks followed by limited exercise for 2 months. ...
