Many countries conduct examinations aimed at monitoring the health of hares and investigating causes for the decrease in the number of this species. These in turn, have resulted in studies into techniques of arterial and venous blood collection in vivo which are not detrimental to the animal’s health. In addition to this, the present study investigated techniques of urine collection in hares. The research material included 42 clinical healthy hares. Before blood and urine collection the animals were pre-medicated with a mixture of ksylazyne 2 mg/kg and ketamine 10 mg/kg i.m. The article also described vessel access (arterial and venous), which permits effective and safe collection of material in adequate amounts.
