Skin carotenoid levels in lactating dairy cows as measured using multiple spatially resolved reflection spectroscopy.

This research communication describes a pilot study measuring skin carotenoid levels of lactating dairy cows. Carotenoids are natural antioxidants, involved in cell communication and immune function, protecting against oxidative stress. They are precursors of vitamin A, important for reproduction efficiency, growth and male fertility. Therefore, easy-to-use, inexpensive methods to measure carotenoids in cattle would provide interesting data for farmers to monitor the health and nutritional status of their herds. In this study, we used a commercially available sensor based on multiple spatially resolved reflection spectroscopy (MSRRS), intended for human use, to measure the carotenoid content in bovine skin in three research herds in France, Ireland and Scotland. Carotenoid levels were measured by applying the sensor to the teat barrel, avoiding pigmented areas of skin. Mean sensor values differed significantly between herds and between diets, with pasture-based animals showing significantly higher carotenoid levels. Our results suggest that MSRRS can be used to accurately to measure skin carotenoids in cows. However, further calibration in bovines is needed to improve of the accuracy of the MSRRS sensor in cattle.

Comparison of 2 recommendations for adjusting the working height in milking parlors.

Milking cows is one of the major labor inputs on dairy farms. Modern parlors allow upright working positions, but pain and disorders among parlor workers are still very prevalent. The platform height in the parlors is important for the body posture of the workers. Based on a large set of data containing parlor-specific measures, anthropometrics, and bovimetrics, a simulation of 2 recommendations published in the literature was carried out. This article presents and discusses the results of 2 formulas for determining the appropriate pit depth. The shoulder and body height of the worker and the distance between the udder and the floor influence the adjustment of the pit depth. If work at shoulder level is favored, autotandem parlors offer the most suitable pit depths, whereas side-by-side parlors are too deep in all cases. Due to the variation in anthropometrics and bovimetrics, a good parlor design can reduce the extent of unfavorable body postures, but more technical measures are necessary to completely eliminate them. Actions that reduce the workload and the prevalence of musculoskeletal pain and disorders should be considered.

Smart Dairy Farming-The Potential of the Automatic Monitoring of Dairy Cows' Behaviour Using a 360-Degree Camera.

The aim of this study is to show the potential of a vision-based system using a single 360° camera to describe the dairy cows' behaviour in a free-stall barn with an automatic milking system. A total of 2299 snapshots were manually evaluated, counting the number of animals that were lying, standing and eating. The average capture rate of animals in the picture is 93.1% (counted animals/actual numbers of animals). In addition to determining the daily lying, standing and eating times, it is also possible to allocate animals to the individual functional areas so that anomalies such as prolonged standing in the cubicle or lying in the walkway can be detected at an early stage. When establishing a camera monitoring system in the future, attention should be paid to sufficient resolution of the camera during the night as well as the reduction of the concealment problem by animals and barn equipment. The automatic monitoring of animal behaviour with the help of 360° cameras can be a promising innovation in the dairy barn.

Addressing Exoskeleton Implementation Challenges: Case Studies of Non-Acceptance in Agriculture.

OBJECTIVES: The objective of this study was to detect success and failure factors for the implementation of passive exoskeletons in agriculture. Exoskeletons have been shown to reduce musculoskeletal loads during lab-based manual tasks, but long-term implementation experiences in agriculture are lacking. METHODS: We analyzed four intervention studies in agriculture focusing on methodological and contextual reasons why the trials were successful or unsuccessful. The study context, attempted intervention, and data collection of each field trial is compared. In the absence of long-term studies investigating the implementation and effectiveness of exoskeletons in agriculture, a set of multi-week pilot trials were initiated among German market vegetable farms and French vineyards from 2019 to 2022. Participant ratings, farm characteristics (e.g. employment duration and payment scheme) and intervention implementation characteristics (e.g. participation in implementation or language barriers) were analyzed using a mixed-methods approach to identify success and failure factors. RESULTS: The comparison of the studies showed that despite the organizational issues, there were several practical issues that limit the success of exoskeleton use in agriculture. We observed that participant rejection of the intervention is a major barrier to successfully conducting long-term field trials in agriculture. Factors like pain, discomfort, heat stress, or a lack of perceived benefits have been identified as failure factors but also the implementation process itself. CONCLUSION: In addition to careful targeting of trial sites and inclusion of participatory elements in the implementation plan, successful implementation of exoskeletons in agriculture requires fundamental human factors development of the exoskeletons themselves. This will require better matching the physical needs of the workers, the production needs of the tasks, and compatibility with the environment.

Youth's (Un)willingness to work in agriculture sector.

Work in agriculture is a significant area of research that highlights the problem of the integration of young people in the former, in particular, in the recent period. Work in agriculture is hard and not prestigious, and young people tend to leave rural areas in the search for alternative activities in urban areas. The study addresses the problem of how the youth should be integrated into agricultural workforce by focusing on identification of the reasons behind the (un)willingness to work in agriculture. The aim of the study is to assess the reasons behind the youth's (un)willingness of work in agriculture, using Lithuania as the case study. The data were collected by means of a questionnaire designed to investigate the perception and opinions toward work in agriculture. The Binary Logistic Regression was used to identify the factors affecting the youth's opinion about (un)willingness to work in agriculture. The study analyzed 430 young people 's responses to the questionnaires survey. The BLR has revealed that youth's unwillingness to work in agriculture is mostly affected by gender, area of residence and youths' beliefs that work in agriculture does not provide any opportunities for self-realization. In summary, this paper argues that the major motivation to work in agriculture is associated with having parents who are engaged in agricultural activities, love of animals and natural environment, and the availability of specialized training. The findings have confirmed the need to attract young people to work in agriculture. Its results are necessary for the scientific community, policy makers, farmers, and practitioners exploring the possibilities for integration of the youth into the agricultural workforce.

Occupational health and safety in agriculture - a brief report on organization, legislation and support in selected European countries.

INTRODUCTION AND OBJECTIVE: Agriculture and forestry are among the most dangerous professions in Europe, with a high level of accidents affecting the sustainability and viability of the sector. International conventions, EU directives and national legislation build the fundamental basis for prevention. The aim of the study is to describe and categorize national mechanisms of occupational safety and health (OSH) for agricultural workers in Europe, to assess the extent of implementing safety regulation, the body in charge, and to give examples of health and safety initiatives. MATERIAL AND METHODS: Results of a questionnaire-survey on basic safety regulations on farms sent by e-mail to the representatives of 30 participating European countries in the context of the Sacurima COST action network (CA 16123) are presented. Due to the complexity, only selected countries are described in this study highlighting the regulative bodies, occupational health services or specific training offers, as well as the complexity of the mechanisms. RESULTS: One of the most serious issues and deficits of EU OSH regulation is the exclusion of self-employed farmers who compose nearly 90% of the farming population. This leads to serious under-reporting of accidents, and because one of the most common measures for the performance of health and safety initiatives are the injury and ill health statistics, better registration systems are urgently needed in almost all countries as a basis for preventive efforts. CONCLUSIONS: The results of the study provide a basis for raising awareness about the current OSH systems in Europe, and the importance of developing sector specific OSH strategies. The proposed activities should assist in tackling high accident rates and poor occupational health for self-employed farmers.

Evaluation of a Physical Ergonomic Intervention for Milking Parlor Operatives - A Case Study.

Musculoskeletal pain and disorders frequently occur among milking parlor operatives on dairy farms, irrespective of the farm size and despite that the work is carried out in an upright position. The objective of this case study was to assess the effect of a new milking system, a physical ergonomic intervention, to reduce the prevalence of musculoskeletal pain and disorders among milking parlor operatives. The new milking system has a reduced cluster weight and single tube guidance and, consequently, abandons the positioning of the cluster underneath the udder, thus reducing the postural load. In a pre/post treatment study the parlor operatives of five farms were questioned, and parlor specifics were measured. The gap between visits was at least one year. There was no significant reduction in pain, but three-quarters of the workers experienced a workload reduction and would recommend the new system. The isolation of the effect of the ergonomic intervention was not possible, because all but one farm completely rebuilt their milking parlors, and several things were changed including work organizational aspects. The expected reduction in pain in the musculoskeletal system was noticed, but not statistically significant. Worker satisfaction and participation in decision making could be improved on the farms and might increase the effect of the intervention, especially because work satisfaction is correlated with the occurrence of pain in the musculoskeletal system.

Epidemiology of Musculoskeletal Symptoms Among Milkers and Dairy Farm Characteristics in Sweden and Germany.

International studies have shown that musculoskeletal symptoms (MSS) and disorders (MSD) are common among dairy farm milkers. Although dairy production is diverse, it has so far not been possible to explain the high risk by production parameters. Two national studies carried out under similar conditions were the incentive to merge the data and increase the sample size. The Standardized Nordic Questionnaire was used to assess MSS prevalence among 92 Swedish and 116 German male and female milkers. Eighty-four percent and 85% of the Swedish and German milkers reported MSS in at least one body part. Highest prevalence was reported in the lower back, shoulder, and neck. Females showed a significantly higher risk of MSS. Apart from that, small significant influence of MSS was found for other risk factors. These findings indicate that technical and organizational modifications of the work place design in milking parlors are needed.

Ergonomic workplace evaluation and epidemiology of musculoskeletal discomfort on German dairy farms.

Previous European studies have shown a high prevalence of musculoskeletal discomfort (MSD) among milking parlor operatives, affecting at least 70% of the staff. The aim of the project was to find correlations between workplace design and prevalence of MSD. For this a data collection was carried out questioning the parlor operatives using a modified Nordic Questionnaire. On farm parlor specifics and bovimetrics of milked cows of a randomly-selected shift were measured. After that data was combined to compare the workplace design and the occurrence of MSD. The results showed that 94% of the female and 71% of the male workers suffered from MSD. The work place analysis revealed that women regularly worked above shoulder level and had to tort and bend more often than men because of the gender specific anthropometrics and the workplace design. The survey took into consideration that not only milking is considered strenuous but other farm tasks as well. The results also demonstrated that there is a need to take action to improve modern milking parlors. The existing helping devices are not sufficient to reduce the workload; reorganizing the work tasks, work schedule and the work place design is suggested.

Ergonomics in modern dairy practice: a review of current issues and research needs.

Dairy farming is an ancient occupation. Traditionally, cows have been manually milked while tethered in stalls or stanchions. In the latter half of the 20th century as machine milking emerged, the parlor milking system has become more popular, especially among larger dairy farms. The transition from manual milking to automatic milking systems as well as the transition from stanchion to parlor milking systems involved a dramatic change in milking tasks. These transitions have resulted in changing patterns of occupational exposure to risk factors for work-related musculoskeletal disorders among dairy workers. However, aspects of the milking task such as sanitization of teats, stripping milk from teats, and attachment and detachment of milking equipment have remained relatively the same. Work-related musculoskeletal symptoms have been reported in the low back, shoulders, hands/wrists, and knees. Research that has measured exposures to risk factors for work-related musculoskeletal disorders among dairy farm workers has been limited, especially when using ergonomic tools to directly measure exposure, such as electrogoniometry or electromyography. Self-reported exposure measures have been most commonly used. The interventions that have been tested to reduce exposure to risk factors for work-related musculoskeletal disorders include assisted lift-hold devices, use of lighter-weight equipment, adjustable flooring, and use of rubber mats. However, research evaluating potential solutions to reduce dairy farm worker exposure to risk factors for musculoskeletal disorders is scarce. Future research efforts should further characterize hazards while simultaneously testing viable solutions that fit within the business model of the dairy farm industry.

The dairy industry: a brief description of production practices, trends, and farm characteristics around the world.

The global dairy industry is composed of a multitude of countries with unique production practices and consumer markets. The global average number of cows per farm is about 1-2 cows; however, as a farm business model transitions from sustenance to market production, the average herd size, and subsequent labor force increases. Dairy production is unique as an agricultural commodity because milk is produced daily, for 365 days per year. With the introduction of new technology such as the milking parlor, the global industry trend is one of increasing farm sizes. The farm sizes are the largest in the United States; however, the European Union produces the most milk compared with other global producers. Dairy production is essential for economic development and sustainable communities in rural areas. However, the required capital investment and availability of local markets and labor are continued challenges. Due to farm expansion, international producers are faced with new challenges related to assuring food safety and a safe working environment for their workforce. These challenges exist in addition to the cultural and language barriers related to an increasing dependence on immigrant labor in many regions of the world. Continued success of the global dairy industry is vital. Therefore, research should continue to address the identification of occupational risk factors associated with injuries and illnesses, as well as develop cost-effective interventions and practices that lead to the minimization or elimination of these injuries and illnesses on a global scale, among our valuable population of dairy producers and workers.

Work-related injuries and fatalities on dairy farm operations-a global perspective.

Agriculture is among the most hazardous sectors for workers globally, and dairy farming has been associated with a high risk of injury among workers in several countries. The purpose of this paper is to provide an update on what is known about modern dairy farms and related injuries and fatalities in different regions of the world. As in other sectors of agriculture, fatalities appear to be associated with heavy equipment usage, whereas injuries occur at higher rates with animal production, specifically cattle and milk production. Dairy farming is associated with higher rates of injury as compared with other industrial sectors, but a lack of work-related injury reporting continues to be an issue in several countries. Worker fatality associated with heavy equipment use is not a new observation (e.g., tractors); however, manure-handling systems, livestock handling, and quad bike operation continue to be associated with worker injuries and fatalities on modern farms. Opportunities exist for improvement of safety-related equipment to reduce injury and fatality risk during worker interactions with large animals and farm equipment.

The effects of working height and manipulated weights on subjective strain, body posture and muscular activity of milking parlor operatives--laboratory study.

The incidence of work-related musculoskeletal disorders among milking parlor operatives has increased while milking parlors were getting bigger. At the same time parlor design was improved regarding the physical load as well as body postures. In contrast to former studies on workload in parlor milking this project was designed and performed as an experimental study in a laboratory setting including 6 female subjects. Motion analysis and psycho-physiological analysis (EMG, heart rate, subjective perceived strain index) were carried out. Intra-individual comparisons were made for the different settings using general linear models for repeated measurements. The effects of working height and weight of milking unit during parlor milking were investigated regarding the impact on muscular load and body posture. The results showed that the optimal working height for attaching the cluster is having the teats at shoulder level of the parlor operative. Another important workload reduction was achieved by reducing the weight of the milking cluster. The named discomfort, localized fatigue and the body posture analysis provide evidence that the changes in modern milking parlors due to mechanization still bear the risk of overburden for the worker.

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.
