Influence of Slaughter Weight, Sex and Intramuscular Fat Content of the MLLT on the Carcass Value of Hybrid Pigs

The aim of this study was to establish the impact of slaughter weight, sex and the intramuscular fat (IMF) content of the musculus longissimus lumborum et thoracis (MLLT) on the carcass value of (Czech Large White x Czech Landrace) x Duroc hybrid pigs. The average lean meat content was higher in gilts (56.51%) than in barrows ( 55.89%). Average IMF content was recorded as 3.76% in barrows and 3.42% in gilts. The slaughter weight of the pigs did have an impact on the IMF content of the MLLT. The higher average slaughter weight (121.61 kg or 120.68 kg) of pigs intended for slaughter was established in pigs with a higher average IMF content (3.52% or 5.20%). Neither sex nor slaughter weight affected the monitored indicators of meat colour. The IMF content of the MLLT had no significant impact on carcass value indicators.
