Study explores labor time-use on Irish pasture-based dairy farms

Globally, dairy producers face increasing challenges regarding sustainability, including declining numbers of workers in the agricultural sector, while continuing to meet increasing demand for nutritious and affordable food. Dairy systems must now focus on more sustainable production that reflects economic, environmental, and social goals. A new report in the Journal of Dairy Science®, published by Elsevier, explores labor time-use on Irish pasture-based dairy farms in the busy spring and summer seasons.

Employment in agriculture, as a share of total worldwide employment, has declined by 29.8% since the year 2000. Due to this reduced availability of workers, management of labor input is becoming a crucial challenge for dairy farms internationally, especially in expanding dairy markets. The seasonal workload associated with pasture-based dairy farming-;a system that promotes farm profitability along with favorable environmental impacts-;combined with increasing herd sizes, has led to a renewed focus on labor time-use and efficiency on these farms.

The study used up-to-date technology, including a mobile phone app, to track labor time-use across 82 spring-calving pasture-based Irish dairy farms from February 1 to June 30, 2019. This allowed the research team to begin examining the often-overlooked social dimension of sustainable farming, including working hours and quality of life.

First author Conor Hogan, of Teagasc Animal & Grassland Research & Innovation Centre (Moorepark, Fermoy, County Cork, Ireland) and the School of Agriculture and Food Science, University College Dublin (Dublin, Ireland), explains, "Each farmer recorded their labor input on one alternating day each week, using a smartphone app. Any labor input by farm workers not using the app was recorded through a weekly online survey."

The team found that milking was the most time-consuming task, representing 31% of farm labor input, making it an important focus for potential improvements in efficiency. The next most time-consuming tasks were calf care (14%), grassland management (13%), cow care (10%), repairs and maintenance (10%), and administration/business (8%). The researchers further report that participating farmers worked, on average, 60 hours a week across the study period, and that the busiest months on most of the farms were February and March.

The team emphasizes the importance of understanding labor use during the most labor-demanding time of year on pasture-based dairy farms, as this points to areas where labor efficiency improvements can be made. As Hogan points out, "Improved time-use in spring and summer, resulting in reduced work hours, can have associated positive effects on many aspects of dairy farming, including enhanced health and safety of farm operators and reduced stress and fatigue among farmers, creating more attractive workplaces and improving farm profitability."
