This study was carried out to elucidate changes in milk production, milk components and milk product properties as influenced by organic and conventional farming system. Milk production in transient organic feeding was lower by 7.6% than that in conventional feeding and also milk fat, milk protein content, solids not fat and somatic cell count were lower than conventional farming system. But, milk lactose content in transient organic feeding was higher than that in conventional feeding. Ca and Fe content in milk in organic feeding tended to be higher compared to conventional feeding. Linoleic acid and unsaturated fatty acids in milk in organic feeding was higher than those in conventional feeding and properties of milk products were improved in organic milk compared to conventional milk.
