This study focused on how haematology parameters differ with different types of anaesthesia that is given to piglets. In this study 18 piglets were used divided into three groups. In each of these experimental groups a different combination of anaesthetics was used. The first group received the combination of azaperone, diazepam, and ketamine. In the second group, we used the combination of azaperone, xylazine, and ketamine. In the third group, the anaesthesia was induced by azaperone, diazepam, butorphanol and ketamine. Blood samples were taken from the piglets three times throughout the procedure and the relevant haematological parameters were determined. With respect to haematological values, the combination used in group 1 appeared as the best for the anaesthesia of pig-lets. The haematological values, such as MCV (mean corpuscular volume), were similar in all groups with the exception of the third group where the MCV and the MCH (mean corpuscular haemoglobin) were significantly lower 24-hour post anaesthesia compared to the other two groups. Lymphocytes in the first two groups showed a steady decrease, while in the third group their levels increased. The opposite trend was observed for the segmented neutrophils that showed a steady increase over the 24-hour period in the 1st and 2nd group while in group 3 their levels decreased. Abolishment of pedal and nasal reflexes to external stimuli applied every 15 min post ketamine administration was observed. The piglets in the 1st group showed no reflexes to external stimuli, while the worst responses were observed in the 2nd group where many of the piglets started to show reflexes very early within the experimental time.
