Young pigs fixation milk teats, which prevent against other siblings. Heavier piglets are more powerful and easier to get in front of the teats sucking, which are richer on milk. The relationship between fixation front and rear teats, sex and subsequent production of valuable meat parts is not sufficiently understood. The aim of the experiment was to investigate the pig meat production carcase with a focus on valuable and the meaty parts (neck of pork, pork shoulder, ham, chops) in relation to gender and fixation teats after birth. Experiment included 4 sows were Large White breed. After their farrowing litter was monitored. In the experiment were included barrows 15 and 16 gilts. Fixation teats piglets were observed from birth to 72 hours after birth at hourly intervals. After reaching slaughter weight of 105 kg pigs were killed. Carcass dissection was done after 24 hours post-mortem. Evaluated the average weight neck of pork, pork shoulder, ham and chops in male and female who occupied front or rear teats. Group males occupying teats front and group males occupying rear teats no significant difference in the monitored parameters slaughter although the average weight of the group males occupying teats back in the pork shoulder and ham was reduced. The group females occupying back teats all monitored parameters were reduced. In the neck of pork and pork shoulder, we noticed a significant difference at (P less or equal 0.01) compared to the group females occupying front teats.
