Plain-English summary
A 5-day-old Simmental heifer was brought in because she was bleeding excessively from her skin after being bitten by horse flies. Despite normal blood tests showing her platelet numbers were fine, further testing revealed that her platelets weren't functioning properly. This issue was identified as a problem with how her platelets worked, rather than their quantity. While the heifer's condition was serious, understanding the specific defect in her blood helped guide her treatment.

Abstract
A 5-day-old Simmental Heifer was evaluated for excessive bleeding from the skin following horse fly bites. A coagulation profile and platelet numbers were normal. In vitro platelet function, measured by whole blood aggregometry, was found to be abnormal when compared with age-matched controls. Therefore, this defect in hemostasis was attributed to a qualitative defect in platelet function.
