        abstract = {The kvorld's livestock production systems are divided into
3 broad categories, based on the degree of integration with
crops and land -- grazing systems, mixed crop-livestock
hrming systenls (MCLS) and industrial systems or landless
systems (Sere and Stienfield 1996). Historically, at low
population densities and land abundant scenario, crop and
animal production are extensive/specialized and hence, croplivestock
interaction is weak. However, as population density
