Przypadek urospermii u ogiera

A case of urospermia in a stallion aged 10 years, coming from the Wielkopolska breed, has been described. The condition resulted in a low efficiency of the semen. Its first fractions were of yellow colour and, in the plasma, an increased level of urea (16.4 mml per 1 1) and creatinine (584 ummol per 1 1) were stated. The libido of the animal was normal; however, the quality of the semen was poor compared with the prior seasons.
