In this context, the productivity and environmental pollution of beef cattle farms in Shiraz were investigated in this study. Nitrogen excretion per ton of meat production waschosen as the pollution index. The results indicated that firms with high production per her cattle create low environmental pollution. Quality of production and feed in clean and pollutant farms shows that good feeding and management practices can reduce manure production per unit of meat produced.     Abstract Pollutions emotion by economic activities is considered greatly byresearchers.
