- Abstract:
- The effect of two different training methods for assessing the parameters body condition and soiling of sows on the inter-observer reliability was analysed in this thesis. For this purpose, a website was created (sauwohl.weebly.com) where information on the parameters and guidance for the assessments were provided. Additionally an online-test, including 34 pictures each for different categories of body condition and soiling, was developed. After finishing the online-test, the agreement with a previously defined gold standard was calculated automatically using Cohen´s Kappa. The trainings were carried out with in total 139 persons, who were allocated to an Online and Presentation group respectively. While the Presentation group was instructed by a lecture based on a PowerPoint presentation, the Online group trained themselves autonomously using the created online-tool. Afterwards both groups performed the online-test in two runs. Prior to the training, the participants had to fill in a questionnaire about their previous experience in assessment of the parameters. While agreement with the gold standard differed between the parameters body condition and soiling, the method of training had no significant effect. The participants obtained better values in the second than in the first run of assessment. In the first run the Online group displayed better agreement with the gold standard than the other participants; in addition experienced assessors complied better in assessing soiling of sows than non-experienced participants. The online training revealed effects on the agreement comparable with training through a presentation. However, it was not tested how the participants would perform when assessing live animals. The online-tool is appropriate for giving users an introduction into the assessment of animal-based parameters, refreshing training contents as well as for regular repetitions and facilitates access to a broad audience due to its flexible utilization.
