The aim of our experiment was to evaluate reproductive traits of dam and sire pig breeds. These breeds were used: Czech Large White (CLW) and Czech Landrace (CL) as dam breeds and Duroc (D) and Czech Large White - sire line (CLW-SL) as sire breeds. In dam breeds better results in production of all (16.70), live born (13.90) and weaned (12.00) piglets were reached in sows of Czech Large White in comparison with Czech Landrace sows with number of all born piglets (13.20), live born (12.20) and weaned (10.70) piglets. Sows of Czech Large White breed reached better results in number of live born piglets per sow and year (33.80) compared to Czech Landrace sows (29.40). In sire breeds better results in reproductive traits were reached in sows of Czech Large White - sire line in comparison with Duroc breed. In sows of Czech Large White - sire line 12.50 of all born, 10.90 live born and 9.80 weaned piglets were recorded. Production of live born piglets per year reached 26.30 piglets. In sows of Duroc breed an average of 11.90 of all born, 9.50 of live born and 8.50 of weaned piglets was reached. Production of live born piglets per year and sow was 21.70 piglets. Birth weights of sire breeds piglets were statistically conclusively higher in comparison with dam breeds. The highest average birth weight (1.77 kg) was recorded in Large White - sire line piglets then in Duroc piglets (1.48), contrarily the lowest average birth weight (1.24 kg) was recorded in Czech Landrace piglets.
