“…Our results are consistent with observations made among other agricultural populations. For example, the average hours per week milking animals was associated with both neck/shoulder pain and elbow/wrist/hand pain in our study sample, a result which is consistent with the observations of several studies among dairy farm workers in the US and elsewhere [Stål et al, , ; Pinzke et al, ; Nonnenmann et al, ; Douphrate et al, , ]. We also observed an association between the average hours per week performing equipment repair and maintenance and low back pain.…”

“…Electromyography was selected as a reliable method that has been successfully used in many studies. For example, Stål et al 11 reported a significant load reduction for the biceps and flexor muscles when using a support arm. The implementation of a support arm could be compared with the Multilactor because holding of the cluster is not required in either system.…”

“…The work routine was very strict and limited to the process of attaching and removing the teat cups. However, the attaching task constitutes approximately 25% of the milking time spent in the parlor 11 and showed the highest load values of all tasks. 10 The study results were only displayed for attaching the teat cups, because the Multilactor has automatic cup removal, as do many other modern systems.…”

“…2 Thus, dairy production is steadily moving to large-herd operations because of associated economies of operative have been carried out on farms. [10][11][12] Their results are task specific but do not regard differences within the tasks such as the variation in working height or the body height of the worker or cow. This paper presents a consecutive experimental study regarding the effects of working height and manipulated weights while attaching a milking cluster.…”

Potential of a Quarter Individual Milking System to Reduce the Workload in Large-Herd Dairy Operations

Large-herd dairy operations utilize parlor milking systems that reduce the physical workload in comparison to tethering systems. Nevertheless, the number of musculoskeletal disorders among workers on dairy farms is not decreasing. In response, a study was carried out to measure the workload focusing on the impact of working height and weight of the milking unit. In this article a new quarter individual milking unit without claw and using single-tube guidance is compared with a light (1.4 kg) conventional unit. A significant reduction of muscular load as well as the reduction of process time was measured using the quarter individual system. Body posture was also recorded using video-based motion analysis. Based on these results, the new system is expected to significantly improve the work place in modern milking parlors by reducing extreme postures as well as the physical and static musculoskeletal load.

Abstract:A portable wireless device with a "vocal commands" feature for activating the mechanical milking phase in conventional milking parlors was developed and tested to increase the level of automation in the milking procedures. The device was tested in the laboratory and in a milking parlor. Four professional milkers participated in the experiment. Before the start of the tests, a set of acoustic models with speaker-dependent commands defined for the project was acquired for each milker using a dedicated "milker training procedure". Two experimental sessions were performed by each milker, with one session in the laboratory and a subsequent session in the milking parlor. The device performance was evaluated based on the accuracy demonstrated in the vocal command recognition task and rated using the word recognition rate (WRR). The data were expressed as %WRR and grouped based on the different cases evaluated. Mixed effects logistic regression modeling was used to evaluate the association between the %WRR and explanatory variables. The results indicated significant effects due to the location where the tests were performed. Higher values of the %WRR were found for tests performed in the laboratory, whereas lower values were found for tests performed in the milking parlor (due to the presence of background noise). Nevertheless, the general performance level achieved by the device was sufficient for increasing the automation level of conventional milking parlors.
