Livestock farming has increased in complexity considerably due to the increased demand for animal products combined with a decreasing number of farmers and ranchers. To meet this challenge, Precision Livestock Farming (PLF) aims to develop fully automated tools that continuously monitor animals, such as cattle. Ineffective cattle management can have significant animal welfare implications, as well as financial consequences for both farmers and the economy because of the size of this substantial industry globally. To our knowledge, no scoping review with explicit published search protocol has broadly examined PLF technologies for both beef and dairy cattle to identify gaps in current research.
