The aim of the research was to investigate the influence of terminal sire line (TSL) and male category (MC) on carcass and meat quality of commercial fatteners. The study was performed on 180 pigs originating from three terminal sire lines: A (Pietrain × Large White), B (pure Pietrain), and C (Pietrain × Duroc × Large White), being assigned to three groups according to MC: immunocastrates (IC, = 60), surgical castrates (SC, = 60) and entire males (EM, = 60). TSL affected most of the carcass and meat quality traits, together with the androstenone concentration. At the same time, MC had a significant effect on fat thickness, ham circumference, drip loss, cooking loss and androstenone and skatole concentrations. A significant interaction effect was observed for carcass length and ham circumference, as well as for most of the measured meat quality traits (except cooking loss, CIE L*, CIE b*, and Warner Bratzler Shear Force (WBSF)). Among the three investigated sire lines, immunocastration was shown to be most beneficial for fatteners sired by the TSL C. However, if deciding to raise EM, fatteners from the TSL B are recommended in terms of carcass and meat quality, although strategies for avoiding boar taint in their carcasses must be taken into consideration.
该研究的目的是调查终端父系品系（TSL）和雄性类别（MC）对商品育肥猪胴体和肉质的影响。研究选用了180头猪，它们来自三个终端父系品系：A（皮特兰×大白猪）、B（纯种皮特兰）和C（皮特兰×杜洛克×大白猪），并根据雄性类别分为三组：免疫去势猪（IC，n = 60）、手术去势猪（SC，n = 60）和完整雄性猪（EM，n = 60）。TSL影响了大部分胴体和肉质性状，以及雄烯酮浓度。同时，MC对脂肪厚度、火腿周长、滴水损失、烹饪损失以及雄烯酮和粪臭素浓度有显著影响。在胴体长度和火腿周长以及大多数测量的肉质性状（除烹饪损失、CIE L*、CIE b*和沃纳·布拉茨勒剪切力（WBSF）外）方面观察到显著的交互作用。在三个研究的父系品系中，免疫去势对TSL C品系的育肥猪最为有益。然而，如果决定饲养EM，就胴体和肉质而言，推荐TSL B品系的育肥猪，不过必须考虑避免其胴体出现公猪膻味的策略。
