The aim of the study was to evaluate parameters of the pork meat quality of 10 pigs by the large white breed in relation to the different load before slaughter. All pigs were dominant homozygotes tested by DNA test for gene marker RYR. On the basis of the effect of the transport load to the observated indexes of the technological meat quality we can state that pigs slaughtered 45 minutes after transport gained from the point of more indexes evidently different parameters in comparison to the group without transport load affection. Values detected in group with load were folowing: pH1 - log molc.(H)+ in musculus semimembranosus 5.81, pH1 - log molc.(H)+ in MLT 5.93, losses by dripping 4.80%, colour of the meat in musculus semimembranosus L* 58.66, a* 4.66, b* 13.07, colour of the meat in MLT L* 62.58, a* 2,91, b* 11.88 and in the group without transport load were find following values : pH1 - log molc. (H)+ in musculus semimembranosus 6.20, pH1 - log molc.(H)+ in MLT 6.22, losses by dripping 2.64%, colour of the meat in musculus semimembranosus L* 51.86, a* 2.17, b* 14.07, colour of the meat in MLT L* 54.99, a* -0.06, b* 10.55. It shows that it is very important to synchronize genetic potential of the animals with the possibility to create suitable breeding environment, but also with influences affected animals during transport and manipulation at the slaughter house and during slaughtering.
