However, since spayed heifers are consuming less feed per day, this extra time on feed only requires an additional 113 lbs of feed per heifer.

Flank spaying has been associated with longer-term pain and higher morbidity and mortality when compared to the Willis dropped ovary technique. Spaying heifers rather than cows reduces the welfare impact, with pain in cows found to be more severe and sustained. If an animal must be spayed, then the Willis dropped ovary technique is preferred.
