dc.description.abstractThe aim of this work was to determine incidence of calving and postcalving reproduction disorders and their effect on the major parameters of cows reproductive efficiency at dairy farm in the R. Serbia. Total number of 1835 high-milking dairy cows (av. milk production >8500L/305d of lactation) records has been reviewed during one year period, at the large dairy farm in area of Vojvodina (R. Serbia). Normal calving and puerperal period without health problems was observed at 583 cows (27,6%), while different abnormalities during and after calving were recorded in 1252 cows (72,4%). The highest percentages of registered peripartal disorders were dystocia and endometritis (62% and 64%, respectively), affecting almost the same percentage of cows. Peripartal disorders had statistically significant influence (P lt 0.05) on the increase of number of services/conception (3,5 vs. 2,7, reproductive disorders vs. healthy cows, respectively), prolongation of the interval from first postpartal insemination till conception (110 vs. 57 days, reproductive disorders vs. healthy cows, respectively), and increase of days open period (214 vs. 146 days, reproductive disorders vs. healthy cows, respectively). This results have confirmed increased incidence of reproduction disorders during calving and postcalving period that significantly reduces reproductive efficiency in high milking dairy cows after parturition.en
dc.description.abstractIstraživanja u mnogim zemljama, tokom poslednjih decenija, pokazuju permanentan pad reproduktivne efikasnosti krava visoke mlečnosti. Cilj ovog rada je da se utvrdi da li i u kojoj meri, peripartalni poremećaji imaju uticaja na osnovne parametre reproduktivne efikasnosti krava u našim proizvodnim uslovima. Istraživanjem je obuhvaćeno ukupno 1835 krava, tokom jedne godine, na jednoj velikoj farmi sa visokom proizvodnjom mleka (prosečna proizvodnja >8500L/305 dana laktacije) u regionu Vojvodine (Republika Srbija). Od ukupnog broja ispitivanih krava, telenje je prošlo bez poremećaja kod 583 krave (27,6%), a različiti poremećaji tokom i posle telenja su ustanovljeni kod 1.252 krave (72,4%). Najčešće ustanovljeni peripartalni poremećaji kod visoko mlečnih krava su teško teljenje (62%) i endometritis (64%). Peripartalni poremećaji imaju statistički značajan uticaj (P lt 0,05) na povećanje indeksa osemenjavanja (3,5 prema 2,7), produženje intervala od prvog do fertilnog osemenjavanja (57 prema 110 dana), kao i na produženje trajanja servis perioda (146 prema 214 dana), u poređenju sa kravama bez poremećaja. Dobijeni rezultati pokazuju da na farmama visoko mlečnih krava povišena učestalost peripartalnih reproduktivnih poremećaja koji značajno utiču na smanjenje reproduktivne efikasnosti krava nakon partusa.sr
