The observation of reproduction trans on the chosen farm

The aim of this bachelor's thesis was the creation of a literature research about the given issue and further demonstration of its practical evaluation of reproductive indicators on the selected farm. The survey was carried out in company ZEAS Březná a.s., farming in the Olomouc region, Šumperk district. In 2015, this company bred 670 Czech Fleckvieh cows and 355 heifers of the same breed. The methodology was based on the monitoring of reproductive indicators relating to cows at livestock production centre in the village Březná and heifers stabled in the village Písařov, within the years of 2013, 2014 and 2015. I was monitoring quantity of inseminations, pregnancy after 1st insemination, pregnancy after all inseminations, service period, intervening time, insemination index and non-return test. The data were gained from the reports about inseminations and pregnancy rates, deadlines for performance control and farm evidence. In the process of the comparison of the results achieved with a population of Czech Fleckvieh cattle bred in the CZECH Republic breeding reaches the above-average values for the entire reporting period in the percentage of pregnant heifers and cows. In 2015 there even was a certain reduction of the insemination interval and service period in relation to the population. Only the interim for the entire reporting period was longer. The observed (group of) cows reached the average pregnancy after the 1st insemination by 48.4% with cows and 66,3% with heifers. Indicator of pregnancy rate after all inseminations got to 49.6% with cows and 61,1% with heifers. Value of the insemination interval ranged within 79.3 days, service period was reaching the length of 121 days and the interim 301,6 days. To conceive one breeding female cow required 1,9 inseminations. For heifers an average of 1.56 inseminations was needed. Milk performance was 7058l of milk per lactation. While making the research milking parlor was going through a modernization, due to which the farm accepted new technologies for the identification of dairy cows, and monitoring of the rut (the so-called vitalimetr). This system should help to improve the reproductive indicators. Then the question remains, how will these new technologies help in the breeding and how they will affect the reproductive indicators
