note = {The main goal of this paper was to propose system innovations, always referring to the supply chain of pig meat, regarding the realization of the following three big challenges: renouncement of tail docking, renouncement of piglet castration and the reduction of antibiotic usage. The term of system innovation is defined within the introductory chapter 1 as interaction of humans/software, technologies/hardware and infrastructure/orgware and illustrated in the subsequent chapters with concrete examples. Three empirical studies (chapter 2-4) illustrate the different opinions of stakeholders in the meat sector on the three measures mentioned above. Chapter 2 shows the results of a study giving an evaluation on the MRSA-risk. The study is based on a combination of an online survey (249 participants) and a accompanying screening (157 participants)
Chapter 3 deals with the intercultural differences between Europe and China dealing with the renouncement of docking tails. Thereby a combination of expert interviews and structured operating audits in China (40 farms) were combined. Chapter 4 presents an evaluation from alternatives to the piglet castration based on a study with 12 expert interviews. The results of the three studies clarify that a system migration can only be realized if there is a common commitment of all the participants within the value chain of meat, which at the same time guarantees the realization of the three measures mentioned above. The results of two experimental studies for the concrete improvement of existing outside health management system form the content of the subsequent chapters 5 and 6. As a first step possible transmission paths of MRSA and ESBL-E in the raising and mast phase of pigs was examined. As a second step, the yardmen were examined. For this investigation different kinds of media such as 86 people, 550 pigs and 70 air samples for (molecularly) microbiological investigations formed the foundational elements. Analyzing these foundational parameters, there is a statistically securable correlation between the frequency of the occurrence of MRSA and ESBL-E. Chapter 6 exposes the results of a study to the definition of six key performances of indicators for the outside controlling of boar fattening.
In addition, data of 294 boar farms within in period of two and a half years (608,466 numbers of supplied boars) were collected. The results of five different standardized trend curves in relation to the smell deviation in the meat, the portfolios and the control charts for the risk estimate and process control as well as a responsibility matrix, were suggested as four elements of visualization.
A matrix with 69 concrete system innovations is presented and described in chapter 7 and builds the major result. The matrix simultaneously considers three different dimensions: humans, technologies and infrastructure. Furthermore, it contains the four elements for innovations: product, service, competencies and component. From this the four crucial action fields for the future were derived:
- Formation of the inter company organization of audits and monitoring activities
- Visualization of results from risk analyses to occurrence and probability of discovery
- Identification of errors and disturbances during biological, technical and organizational processes as well as the definition from key indicators to the control
- increase in intensive co-operation between science and practice using a common research and development database as well as the use of simulation programs.
To sum it up, the better the animal holders are informed about changes within the system or actively being integrated in research projects, the more their behavior towards proposals of change transforms into open-minded ideas.},
