The Precision Livestock Farming (PLF) concept and tools have started to globally permeate the livestock farming industry due to its immense impact and multifaceted benefits. However, many farmers are still hesitant to adopt PLF, owing to lack of information on its implementations and outcomes. It is meaningless if technology remains confined to paper and within the walls of institutions. The idea for the book Precision Livestock Farming was conceived during an interface between the extension specialists and the scientific and academic community on Precision Livestock Farming organized by the ICAR-ATARI, zone-I, Ludhiana with technical support from the Guru Angad Dev Veterinary and Animal Sciences University Ludhiana. The book intends to give a spark of inspiration to the young generation of farmers, extension experts, academicians, and scientists to venture towards innovation and adaptation of the PLF tools. The experts technical inputs from the interface are compiled into a book format for scientists, extension specialists, and farmers to use as a ready reference. Surely, this book will give the reader a new insight into the different livestock aspects.
