Mass Balance Concept in Livestock Farming

Mass balance is also known as material balance. It is a practice of accounting for matter entering and leaving into a system which may be helpful in understanding the conservation or steady state of the system under analysis [1]. The exact conservation law used in the analysis of the system depends on the context of the problem but limited to mass conservation, i.e. that matter cannot be destroyed or be created spontaneously. The basic principles of mass balance are applicable to understand about a system stability or steady state, mostly in the field of engineering and environmental analysis. Generally, the principle of material balance can be applicable to design chemical reactor or to understand the stability of an ecosystem under variable conditions. The principles of mass balance are also applicable to livestock production system management in order to bring sustainability in the system.
