Aim Treatment of pigs before slaughter and the impact on the quality of meat is to report measures the welfare of pigs in lairage meat industry Pik Vrbovec by which it is possible to reduce the proportion of PSE meat in pork loin. Slaughter pigs prior stressful events that affect the quality of meat, and measures of well-being it can reduce stress and affect the quality of meat. The investigated practices before slaughter were related to the stay of pigs in lairage, treatment of workers with pigs in the depot, routing pigs to the gas chamber and the common control sensor that determines the level of CO2 in the gas chamber because of more efficient stunning. Length of stay in the animal depot was reduced to 12 hours and more on an average of 4-5 hours, to reduce the aggressiveness of the animal depot and reduce the incidence of the fight. Dealing with pigs and guidance during unloading and forcing the stun is done gently, quietly, and avoiding any rough treatment of pigs. Electrical Probe Set during the eviction pigs prohibited. Within the section of Corridor are made sections where the pigs can calm before entering the gas chamber. More frequent control sensor for stunning that measures the level of CO2 is a prerequisite for proper stunning. The share of PSE meat is continuously decreasing through the period that justifies the introduction of specific measures of well-being and this is in 2015, compared to the observed period in 2014, the share of PSE meat decreased by 1.77%. The higher amount of allocated PSE meat as well as greater total quantity of processed ham was determined before the introduction of measures of well-being. The difference of 3,045 kg between methods of well-being (before uvođenih measures and the introduction of measures) was statistically highly significant (P <0.001) for the parameter, the quantity of PSE meat, while the determined difference of 32,300 kg between methods of well-being for the total quantity of processed ham is not was statistically significant (P> 0.05). The introduction of new measures of well-being it was justified because it significantly reduced the proportion of unwanted (PSE) meat leg.
