As cow-calf  producers have strived to improve weaning weights, one of the disappointing side effects of the emphasis on growth in the cattle industry has been increased calving difficulty in first calf heifers. Survey in many  states indicate that from 25 to 50% of the beef heifers require assistance at calving. In some herds, this incidence may be as high as 75 to 870 %. Research has clearly shwn the  detrimental economic effect of calving difficulty in first calf heifers. Research¹ at  Miles City, Montana, reported that 57% of all calf deaths at birth were dystocia related. A study² at the Meat Animal Research Center,  Clay Center,
Nebraska, analyzed 5,064 parturitions over a 6 year period and found that calf losses at or near the time of birth were four times greater in calves experiencing dystocia than in those born unassisted.
