“…Goal of incorporating technologies on dairy farms is to maximize animal performance, and thus to detect diseased cows and production problems early, in order to monitor herd level health and to minimize the use of medication through preventive health measures. Examples of these technologies are sensors that measure body condition, pH of the rumen, urea, or activity meters for estrus detection (Rutten, 2017). However, the first application of the use of sensors on farms was for the detection of clinical mastitis with electrical conductivity sensors (Nielen et al, 1992;Hogeveen et al, 2010).…”
