摘要：

Aim of this study was to compare selected reproduction indicators of Holstein cattle at two farms. The data gained in 2014 a 2015 were compared. In the observed cow population values of the 1st inseminations, all inseminations, re-inseminations, cow pregnancies after the 1st insemination and all inseminations, interval, gestation period and conception rate were compared. The conception rate after all the inseminations at the both farms (32.16 to 39.57%) was almost in accord with the average rate in the Czech Republic. The gestation period values (103.83 to 144.26 days) and interval values (66.17 to 88.18) were of an average or even substandard level. These two herds shall be classified as of a low level of reproduction.
