Abstract: This study was conducted to evaluate the quality of raw milk produced by the 140 dairy cow farms at different locations of Lordegan region. Solid Non Fat (SNF), Crud Protein (CP), fat, density, Dry Matter (DM), water and freezing point of samples were measured. The result showed that milk compositions of dairy farms were containing 87.42±1.13% water, 8.67±0.69% SNF and 12.57±0.69% total solid matters. Solid matters were including: 3.90±0.97% fat, 3.2±0.22% protein and 5.03% lactose and other minerals and vitamins.
