Work on pig enhancement will continue to deal with improving reproduction characteristics, growth characteristics, feed utilization, trunk and meat quality, and management confidence. On the one hand, adequate methods of quantitative and mollecular genetics will be used, and on the other there will be efforts to increase probability that genetic potential of the animal is exhibited in practical conditions. The objective of this work was to see how and to what extent genetic potential in swine is exhibited in practical conditions. The variability of production characteristics of swine in farms in the Republic of Serbia was examined during a period of 10 years (1991-2000). Reproductive, fattening and trunk quality characteristics varied 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
