Abstract:V raziskavi smo proučevali dolžino poporodnega premora in dobe med telitvama na območju Koroške regije. Podatke smo pridobili s Kmetijskega inštituta Slovenije za šest koroških občin, kjer smo izbrali deset največjih proizvajalcev mleka z raznoliko pasemsko sestavo. Podatke smo obdelali za obdobje desetih let (1998–2008). V obdelavo je bilo vključenih 8.264 krav s povprečno 2,86 zaporednih telitev. Največ je črno-bele pasme (5.972), sledita ji lisasta (727) in rjava (859) pasma. V statistični model smo vključili vpliv občine, pasme ter interakcijo med občino in pasmo. Ugotovili smo, da sta poporodni premor (od 96 do 135 dni) in doba med dvema telitvama (od 380 do 416 dni) v nekaterih koroških občinah nekoliko daljša od priporočil v literaturi. Krave imajo v povprečju 6.373 kg mleka v standardni laktaciji glede na občino in 6.096 kg mleka glede na pasmo. Največ mleka v standardni laktaciji imajo krave črno-bele pasme (6.935 kg). Povprečni poporodni premor vseh pasem (120 dni) v obravnavanih koroških občinah (121 dni) je za deset dni krajši od slovenskega povprečja. Glede na občine (404 dni) in pasme (406 dni) je tudi doba med dvema telitvama na Koroškem krajša od slovenskega povprečja (415 dni). Da bi obdržali poporodni premor in dobo med telitvama na Koroškem vsaj v takšnem stanju, ali ju celo skrajšali, bodo rejci morali v večji meri skrbeti za prehrano, odkrivanje pojatev in pravočasno osemenjevanje krav.

Title:DAYS TO CALVING IN CARINTHIA REGION
Abstract:In the study we investigated the length of the postpartum period and days to calving in the region of Carinthia. Data were obtained from the Agricultural Institute of Slovenia for six Carinthian municipalities, where we selected the largest ten milk producers with a diverse breed composition. Data were analyzed for a period of ten years (1998–2008). There were 8264 cows included in the analysis with 2.86 parities on average. The majority is represented by Black and White breed (5972 cows), followed by Simmental (727 cows) and Brown breed (859 cows). The statistical model included the effect of the municipality, breed, and the interaction between the municipality and breed. We found out that the length of postpartum period (96 to 135 days) and days to calving (380 to 416 days) in some Carinthian municipalities are slightly longer in comparison to the recommended ones in the literature. On average, cows have 6373 kg of milk per standard lactation according to the municipality and 6096 kg of milk according to the breed. Black and White cows have the highest milk yield in standard lactation(6935 kg). The average length of the postpartum period of all breeds (120 days) in the studied Carinthian municipalities (121 days) is ten days shorter in comparison to the Slovenian average. With regard to the municipalities (404 days) and breeds (406 days), the period to calving in Carinthia region is also shorter than the Slovenian average (415 days). To keep the length of the postpartum period and days to calving in Carinthia region at least in this condition or even shorten them, farmers will need to put great emphasis on nutrition, oestrus detection, and timely insemination of cows.
