The surgical castration of male piglets as a routine procedure in modern pig production is facing increasing societal criticism. Pork production with boars and immunocastrates are available alternatives, but both have low market shares as it is so far uncertain how the carcass characteristics and primal pork cuts of boars and immunocastrates will be estimated in comparison to barrows and gilts. This article therefore evaluates the impact of sex group (gilts, boars, immunocastrates and barrows) on carcass characteristics and primal pork cuts using AutoFOM III data from a commercial abattoir. In our study, weekly slaughter data from a total of n = 36,994 pigs between 2018 and 2019 were analyzed. The results show that gilts had the highest amount of pork per carcass of all sex groups, whereas non-significant differences between boars, immunocastrates and barrows could be observed. Boars had the highest lean meat content, followed by gilts, immunocastrates and finally barrows with the lowest lean meat content. These results suggest that both immunocastration and pork production with boars are sustainable techniques that can replace pork production with barrows without affecting carcass quality.

利用商业屠宰场的AutoFOM III数据，对Gil鱼，公猪，免疫接种动物和手推车的体特征和原始猪肉切片

在现代养猪生产中，雄性仔猪的手术cast割作为常规程序正面临越来越多的社会批评。可以使用公猪和免疫production割的猪肉生产替代产品，但是两者的市场份额都很低，因为到目前为止，与公猪和后备母猪相比，如何估计bo猪和免疫cast割的car体特征和原始猪肉切割量尚不确定。因此，本文使用来自商业屠宰场的AutoFOM III数据，评估了性别群体（后备母猪，公猪，免疫and割动物和公猪）对characteristics体特征和原始猪肉块的影响。在我们的研究，从总的每周屠宰数据ñ在2018年至2019年之间分析了36,994头猪。结果表明，在所有性别组中，小母猪的per体猪肉含量最高，而公猪，免疫cast割和公猪之间的差异不显着。公猪的瘦肉含量最高，其次是小母猪，免疫cast肥，最后是瘦肉含量最低的公猪。这些结果表明免疫cast割和用公猪生产猪肉都是可持续的技术，可以用公猪代替猪肉生产而又不影响car体质量。
