Abstract:Raziskavo smo opravljali v obdobju od leta 2010 do leta 2012 na dveh kmetijah s kravami dojiljami lisaste pasme. Analizirali smo 45 porodov (37 pri kravah in 8 pri telicah). Preučevali smo različne parametre v obdobju pred in med telitvijo. Pred telitvijo smo spremljali različna predhodna znamenja. Ugotovili smo, da so se ta začela pojavljati v obdobju enega tedna pred telitvijo (mehčanje vezi 7 dni, nabrekanje vimena 7 dni in prisotnost mleziva v vimenu 2 dni pred telitvijo), topitev materničnega čepa pa se je začela že 8 dni pred porodom. Pri telicah se je vime začelo razvijati dva meseca in pol pred telitvijo, mlezivo pa je bilo prisotno 4 dni pred telitvijo. Pri telitvi smo ugotovili, da se je alantoisni mehur pojavil 36 minut pred nogicami teleta, tele pa je bilo porojeno v dobrih 14 minutah. Večina telet (95,6 %) se je otelila v normalni prednji legi. V fizioloških mejah (do 12 ur po porodu) je bila izločena tudi posteljica. Pri živalih, ki so bile vključene v raziskavo, je brejost v povprečju trajala 290 dni, doba med dvema telitvama pa 385 dni.

Title:Reproduction and birth parameters of Simmental suckler cows
Abstract:The research was carried out in the period from 2010 to 2012 on two farms with suckler cows of Simmental breed. The analyses comprised 45 births (37 in cows and heifers at 8). We studied different parameters in the period before and during calving. Before calving, various preliminary signs were monitored. We have found that they started to emerge in the period of one week before calving (softening ties 7 days, 7 days udder swelling and the presence of colostrum in the udder 2 days before calving). Dissolution of the cervical cap had already started 8 days before birth. In the heifers, the udder began to develop two and a half months before calving, while colostrum was seen 4 days before calving. At calving, we found that the allantoic bladder appeared 36 minutes before the feet of calves. The calf was conceived in about 14 minutes. Most calves (95.6%) were calved in the normal front position. Placenta was also eliminated within physiological limits (up to 12 hours after birth) bed. For studied animals, the average length of gestation and calving interval were 290 and 385 days, respectively.
