Sustainability in Ruminant Livestock : Springer : 9789813343429 : 9813343427 : 21 Jan 2021 : This book presents a concept for implementing a mass balance approach toward developing an effective eco-friendly, livestock farming system independent of external energy input. In this context it describes a modern, integrated farming system, and includes comprehensive technical information explaining the design and evaluation of manure management systems, and modeling and operational tools. It first discusses the mass balance operating process, highlighting the difference between imported and exported mass across the farm boundary. Estimating mass balance can provide critical information for (comprehensive) nutrient management planning and for managing the movement of nutrients and manure. It then explains the estimation of whole-farm P mass balance using a suitable model system. The subsequent chapters provide updated information on management aspects of livestock-farming and generation of
