Alt oder Neu - Welche Rassen passen für die ökologische Schweinefleischerzeugung?

Autores: Weißmann, Friedrich; Baulain, Ulrich; Brade, Wilfried; Werner, Daniela; Brandt, Horst.
In der ökologischen Schweinemast wird immer wieder über die Eignung alter und moderner Schweinegenotypen sowie die Notwendigkeit eigener Zuchtprogramme diskutiert. Um beide Punkte beantworten zu können, sind Informationen über das Ausmaß möglicher Genotyp- Umwelt-Interaktionen bei relevanten Leistungsmerkmalen notwendig. Daher wurden 682 Schweine von 7 merkmalsdifferenzierten Genotypen auf zwei Leistungsprüfungsanstalten in jeweils ökologischer und konventioneller Haltung auf Merkmale der Mastleistung sowie Schlachtkörper- und Fleischqualität geprüft.  Es zeigte sich, dass in der Mastleistung und der Schlachtkörperqualität sowohl die modernen den alten Genotypen als auch die konventionellen den ökologischen Prüfbedingungen überlegen waren. Beim...

The suitability of indigenous or modern genotypes for organic conditions and the necessity of a specific organic breeding programme are intensively discussed in the organic pig fattening scene. To clarify both items information about Genotype-Environment-Interaction (GEI) is necessary. Therefore 682 pigs of 7 different genotypes with widely spread protein synthesis capacity were tested for growth performance and carcass quality under conventional and organic environments at two performance testing stations in order to verify GEI. The modern genotypes were superior to the old ones, all genotypes achieved significantly better results within the conventional environment and there were significant interactions between genotype and environment for all criteria...

Zur Genotyp-Umwelt-Interaktion von Fleischqualitätsmerkmalen bei unterschiedlichen Genotypen in ökologischer und konventioneller Schweinemast

Seven different pig breeds were kept under conventional and under organic feeding and housing conditions on two performance testing stations to analyse genotype-environment interactions for meat quality traits. Genetically controlled physical pork quality traits like pH- and EC-values are unaffected by both housing and feeding systems and no genotype-environment interaction could be found. In contrast, chemical meat characteristics like intramuscular fat content and fatty acid pattern are strongly influenced by genotype and feeding and a significant genotype-environment interaction. But no considerable reranking could be observed. The differences are caused by the differences in energy and amino acid supply between environments and variable lean meat...

Die Mastleistung und Schlachtkörperqualität unterschiedlicher genetischer Schweineherkünfte in konventioneller und ökologischer Haltung

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,...
