The development and current status of pig insemination in Poland was analyzed. A particularly dynamic trend in the last few years was determined. During 1993 about 430 thousand of inseminations of sows were carried out, that is about 17% of their total number. On the basis of current data it is possible to prognose an increase of cases of insemination to 23% of the total sow population. A positive influence of insemination on mean production in Poland was found. Insemination can be an effective means of reproduction and an important factor in breeding and production programs. Different progress, possibilities and scale of application of insemination were determined in different regions of Poland. The largest number of sows is inseminated by this method in leszczyńskie (49%) and skierniewickie (38%) voivodships; in nowosądeckie, ostrołęckie and wałbrzyskie voivodships insemination of sows is not carried out.
