Abstract
In this study, a group of 11 Holstein-Friesian bulls used for semen production has been monitored. Due to inadequate living space, some of bulls (experimental group, n = 5) with higher body measures developed ulcera and blisters on claws and distal extremities. At the beginning of the trial these animals were treated by surgical removal of ulcera, claw correction and supportive therapy. The other bulls (control group, n = 6) only had claw correction. All 11 bulls were monitored daily for next 90 days following surgery. Blood samples were collected weekly for haemogram and clinical biochemistry. After short interval of recovery, bulls were returned in semen collection and spermiograms were performed regularly. According to laboratory data, bulls after surgery and during supportive therapy (n = 5) had shown changes specific for reversible renal damage and endotoxaemia (altered total proteins, creatinin, urea, lymphopenia) for more than 30 days, although they appeared clinically healthy. All bulls that were cured for ulcera and blisters, were returned back to semen collection and gave ejaculat of acceptable quality. There was no noticeable difference in spermiograms of two investigated groups of bulls.
