Resumo: | A study was conducted to examine growth and carcass composition of genetically different pigs under conventional and organic conditions. The pig genotypes were Bundeshybridzuchtprogramm (BHZP), Schwäbisch Hällisches Schwein (SH), Angler Sattelschwein (AS), Piétrain x SH (PIxSH), Piétrain x AS (PIxAS), Piétrain x Deutsches Edelschwein (PIxDE) and Duroc x Deutsche Landrasse (DUxDL). A total number of 650 pigs were kept at two test stations. This paper presents results of the test station Neu-Ulrichstein where the genotypes BHZP, SH and PIxSH were tested. Growth and carcass chracteristics of 80 pigs per environment (conventional housing and feeding vs. organic housing and feeding) were analysed using a linear model including the fixed effects of sex, genotype, environment and the interaction of geno-type and environment. Genotype was found to have a significant influence on growth and carcass quality, whereas the BHZP-pigs had a higher daily gain, meat percentage and meat to fat ratio. The influence of the environment was significant for daily gain only, with pigs under conventional conditions gaining 110 g more than pigs under organic conditions. No statistically significant interactions between genotype and environment could be found for this part of the study. With exception of the feed con-version ratio under conventional conditions, the BHZP-pigs showed the best perform-ance and carcass quality in both environments when compared to the PIxSH- and SH- genotypes.
