Have a three and a half year old cow, that is due to calf in six or eight weeks. Today when I checked on them, she had a prolapse uterus.. I ran her into the head shoot , washed it off and pushed it back in side her. In seemed to return to the proper place with a sucking noise.. Gave her 36ml of oxytetracycline... She did not seem to be in labor, this is my frist ever .. Causes? What to expect? She is penned up with a buddie ,. Doc what do you think....
