Smart livestock farming (SLF) is a convergence service where Information and Communication Technologies (ICT) are applied into the livestock value chains. It has the potential to deliver a more productive and sustainable production by integrating processes of the smart farming, Management Information Systems (MIS), stockbreeding automation and robotics to provide a better decision making or more effective exploitation operations and management of livestock value chains. The use of Internet of Things (IoT) technologies in the SLF aims at providing a full coverage of the processes by collecting and transmitting data from the entire agroecosystem. That means SLF can establish contact with each participant of a livestock chain, bringing and collecting information about their processes, increasing the possibilities for control and improvement on the efficiency of their tasks. This Recommendation provides an overview of SLF based on IoT, high-level requirements for SLF, as well as a reference model which represents a generic sequence for the livestock value chains and is applicable to these chains as a whole, regardless of species or rearing techniques.
