The Influence of Blood-Sampling Technique on Lactic Dehydrogenase (LDH) in Pig Plasma

Blood-sampling from animals can be done in several ways without interfering with the results from analysis of many substances in the blood. For such labile substances as plasma enzymes, it should be realised, however, that certain methods of sampling can give rise to false results. By collection from animals during slaughtering there is the risk that such conditions as excitement and anaesthesia interfere with the results of the blood-analysis.
