One of the AgriDataValue project pilots is located at a dairy barn in Vecauce, Latvia. Vecauce is a multidisciplinary farm that combines student training, research, crop farming, dairy farming, biogas production, fruit growing, forestry, and has developed one of the largest and most productive herds of dairy cattle in Latvia. The barn houses more than 1,000 cows. In this dairy barn, various research trials are conducted on topics such as feed components and efficiency, enteric emissions, colostrum quality, youngstock management, and more. The collected data includes individual cow identification, general cow information, milk production, milk quality, and other related metrics. Production data is supplemented by feed data, milk data (including production, fat, protein, lactose, and urea), animal weight, and other parameters.

Several systems that generate relevant data are installed in the dairy barn. Most of these systems were already in place before the start of the AgriDataValue project and are part of the general barn infrastructure; however, they still provide essential data needed for the project’s modelling tasks. One of the key systems is Afimilk (Figure 1), which is used to monitor milk parameters and identify milk content. This data is further utilized to assess and analyze cow health. Additionally, pedometers are used to monitor animal activity and behavior (Figure 2).
