The variability of production characteristics of swine in farms in the Republic of Serbia (Yugoslavia) was examined during a period of 10 years (1991-2000). Reproductive, fattening and trunk quality characteristicsvaried among farms, genotypes and year of investigation. The average revealed analyzed characteristics in swine are not satisfactory. There is a wide range in the variation of all characteristics among the farms. There are differences between the characteristics of the same swine genotype with regard to the tendency they exhibit per year or farm. Some of them have not shown a clear tendency to increase or reduce, but varied from year to year. The effects of selection and cross-breeding differed considerably.
