Abstract

The present experiment was conducted to ascertain the effects of restraint with a pigkeeper and venipuncture on blood constituents, using 6 piglets. Each animal was implanted with a jugular venous catheter for collecting blood 7 days before the onset of the experiment. Restraint with a pigkeeper was continued for 5 min and several times of needle pricks were carried out during that time, and blood samples were taken through the catheter before and after irritations. In the control experiment, in the same animals blood was similary collected through the catheter without irritation one day before the main experiment. RBC count and Ht and Hb values were marked and transient increases 5 to 10 min after the restraint and needle pricks were noted. WBC count showed an increase with 2 peaks, at 5 and 60 min after irritation. Plasma cortisol and glucose levels also increased remarkably in response to the irritation. It was suggested that blood collection with a pigkeeper might have been stressful to the swine.
