Abstract

Malignant hyperthermia of swine (MHS) is producing a major economic problem in pig breeding due to increased loss of piglets during the breeding and frequent occurrence of losses (mortality) in transport, especially at elevated temperatures. PSS causes pigs having lower meat quality and the processing of affected pig's meat brings larger losses in processes, which is all reflected in the quality of preserved food products. In Croatia, the systematic monitoring of PSS status and molecular genetic methods, in populations of commercial pig breeds is carried out since 2003 as part of implementing the national program of pig breeding. Testing the selected breeding pigs is carried out in the laboratory of Department of Central animal gene bank placed in Croatian Agricultural Agency, which is responsible for systematic monitoring of PSS on the national level. Status of PSS in systematically monitored by the methods of molecular genetics, Polymerase chain reaction (PCR). The aim of this paper is to show the results of monitoring the status of PSS in Croatian pig production from year 2003 to 2014, in which a total of 4363 boars of commercial pig breeds were tested. Results of laboratory tests of breeding boars and monitoring the PSS status in Croatian pigs for a period of more than a decade, indicate the success of protocol sets for monitoring and eliminting the breeding males of commercial pig breeds that are PSS positive. This conclusion is confirmed by the continuous rise in desirable genotype (HalNN and HalNn) proportion of tested boars and reduction of Halnn as undesirable genotype. As one of the findings of this research is the fact that tracking of PSS status in Croatia applies only on the commercial breeds, but not on two native breeds of pigs (Black Slavonian and Turopolje pig) of which a high - quality traditional meat products are made, and that is the reason why it should be important to monitor PSS status in these two populations on regular basis.
