It was investigated the influence of normal (100 ml) and reduced (50 ml) dose volume, after classical intracervical or intrauterine insemination, on the sow fertility (farrowing rate and litter size). Classic intracervical insemination was performed in the total of 50 sows (25 inseminated with 100 ml doses and 25 with 50 ml doses). Intrauterine insemination was performed in the total of 50 sows (25 inseminated with 100 ml doses and 25 with 50 ml doses). Significant greater farrowing rate (88%) and live born piglet per litter (10.77 or 11.86) was found after intrauterine insemination, then after intracervical insemination (76 or 72% farrowing rate, and 10.42 or 9.89 live born piglets per litter). Obtained results suggest that intrauterine insemination can be performed by significant reduction of dose volume, without decreasing sows fertility. It can result in significant increasing of boar reproductive efficiency.
