Analiza uspešnosti osemenjevanja govejih plemenic na območju veterinarske postaje Slovenske Konjice

Ugotavljali smo uspešnost osemenjevanja govejih plemenic na območju Veterinarske postaje Slovenske Konjice v obdobju enega desetletja (2001—2009). Raziskali smo različne dejavnike, ki vplivajo na uspešnost osemenitev govejih plemenic. V raziskavo je bilo vključenih pet veterinarjev, ki so v desetih letih opravili 43.687 osemenitev. Izmed teh osemenitev je bilo 7.086 prvih osemenitev telic in 36.601 prvih osemenitev krav. S semenom plemenskih bikov lisaste pasme je bilo osemenjenih 85,2 % govejih plemenic, s semenom plemenjakov mesnih pasem 7,8 %, s semenom črno-bele pasme 5,5 % in s semenom rjave pasme 1,6 % krav in telic. Povprečni NR vseh osemenjevalcev v obdobju enega desetletja znaša 65,6 % Ugotovili smo, da ima na uspešnost osemenitve precejšen vpliv izvajalec osemenitve, saj je razlika med najslabšim in najboljšim veterinarjem v uspešnosti osemenitve 8,29 %. Ugotovili smo, da uspešnost osemenitve po letih pada, saj je v obdobju 2001—2009 padla za 6,9 %. Dokazali smo, da je uspešnost osemenitev pri telicah večja kot pri kravah. During a ten-year period, we observed the performance of insemination of pure bred cattle female in area of the Slovenske Konjice Veterinary station. Different factors influencing the performance of insemination of pure bred cattle females were observed. In the survey, there were five veterinarians involved who, over the period of ten years, performed 43,687 individual inseminations. Among those, there were 7,086 first-time inseminated heifers and 36,601 of first-time inseminated cows. 85.2% pure bred cattle females were inseminated using the semen of Simmental breeding bulls, while 8.7% were inseminated using the semen of different stud meat breeds, 5.5% of the semen came from the black-white breed, and 1.5% of the cows and heifers were inseminated using the semen of the brown breed bulls. The average NR of all inseminators in the period of ten years is 65.6%. We came to the conclusion that the successful performance depends on the veterinarian, ranging up to 8.29%. Further, we found that the performance has declined in the last few years, as much as 6.9%, so it has been proven that successful performance of insemination in heifers tends to be higher than in cows.
