Sažetak
Better slaughtering and fattening results have induced more frequent fattening of young uncastrated boars. While fattening boars, the problem of unpleasant odour from the boar meet, which is caused by endosteron, scatol and other testicular hormones, often occurs. There are some differences between genetic bases of swine in extracting of these hormones. Therefore, the aim of this paper was to pay more attention on legitimacy of slaughtering Swedish Landrace uncastrated boars. The experiment was carried out on a group of uncastred boars and a group of uncastrated gilts. The groups were composed of 15 accidentally chosen pigs per group from 15 different litters (one male and one female pig from eash litter). The experimental fattening lasted for 95 days (from 30 to 90 kg of body weight) and the pigs were fed ad libitum. The boars had significantly higher daily growth rate (660 g vs. 640 g, P<0.05), thinner back fat, higner meatiness of pork sides (56.92% vs. 54.53%), lower share of back part (14.83 vs. 18.94%) and higher share of shoulders (15.02% vs. 13.29%) than the gilts. Furthermore, the differences in meat quality according to sex were also determined. The boar meat had mo re unpleasant odour, significantly lowe rate of water (72.91% vs. 73.72%) and ashes (1.05 vs. 1.08%) and higher rate of crude proteins (23.49% vs.22.55%) than the gilt meat. The rate of crude fat in the boar meat was lower than in the gilt meat, but without significant differences (1.85% vs. 2.14%). Concerning pH1 and pH2 values, water fixation ability andmeat colour, there were no significant differences determined according to sex (P>0.05). The pork sides were dissected according to the method by Weniger et al. (1963).
