I have used it on open females with foot before but not on one that could be pregnant. It is a heifer that has only been exposed a couple months. When I have used it I got better response that with LA 300 but the label worries me:
"The effects of DRAXXIN on bovine reproductive performance, pregnancy, and lactation have not been determined. Subcutaneous injection can cause a transient local tissue reaction that may result in trim loss of edible tissue at slaughter."
