The aim of this study was to determine the efficiency of intracornual insemination versus uterine body insemination using a standard insemination dose. All cows have synchronised oestrus with Ovsynch protocol and only cows with strong oestrus signs were inseminated. An experiment was conducted in autumn. In group I 36 cows were inseminated into the uterine body and in group II 33 cows were inseminated into the uterine horn ipsilateral to the ovary with the largest follicle determined by ultrasonography. The conception rate was 69.44% in group I and 69.66% in group II (there were no significant differences). It was concluded that in routine insemination practice the site of semen deposition (into uterine body or into ipsilateral horn) does not play a significant role.
