Summary

ZCastrated heavy pigs of > 160 kg body weight are used for traditional pork specialties (e. g. air-dried sausages) due to the required fat quantity and quality. Today most organic production systems use modern hybrids (Hy) with often insufficient fat features. The use of endangered breeds with high body fat synthesis capacity, e. g. German Saddleback (Sa), could be an alternative with a positive effect on maintaining biodiversity. This study with a total of 132 castrates analysed the effects of 3 different genotypes (Sa, Piétrain*Sa, Hy) and 2 different roughage sources (grass-clover-silage, straw) on performance, carcass-, meat-, fat-, and product-quality. The present paper deals with performance (PF) and carcass quality (CQ). It was found that PF and CQ are both influenced (p<0.0001) by the genotype but not by the roughage source. Hy showed the best and Sa the poorest PF (e. g. 804 g vs. 624 g daily weight gain). Concerning SQ, Sa showed the highest and Hy the lowest fat yield (32.2 % vs. 54.2 % lean meat content). Piétrain*Sa always ranked in the middle. It is concluded that endangered breeds are suitable for traditional air-dried sausage production from the viewpoint of PF and CQ.
