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 = 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.
在现代养猪生产中，将雄性仔猪去势作为常规操作正面临越来越多的社会批评。使用公猪和免疫去势猪进行猪肉生产是可行的替代方案，但目前这两种方案的市场份额都很低，因为与阉公猪和小母猪相比，公猪和免疫去势猪的胴体特征和主要猪肉切块如何评估尚不确定。因此，本文利用一家商业屠宰场的AutoFOM III数据，评估了性别组（小母猪、公猪、免疫去势猪和阉公猪）对胴体特征和主要猪肉切块的影响。在我们的研究中，分析了2018年至2019年间总共36994头猪的每周屠宰数据。结果表明，在所有性别组中，小母猪每头胴体的猪肉量最高，而公猪、免疫去势猪和阉公猪之间未观察到显著差异。公猪的瘦肉含量最高，其次是小母猪、免疫去势猪，最后是瘦肉含量最低的阉公猪。这些结果表明，免疫去势和使用公猪进行猪肉生产都是可持续的技术，可以在不影响胴体质量的情况下取代使用阉公猪的猪肉生产。
